Capture Image from Camera and Display in Activity

Question

I want to write a module where on a click of a button the camera opens and I can click and capture an image. If I don't like the image I can delete it and click one more image and then select the image and it should return back and display that image in the activity.

Ulceration

you should open a camera intent, capture an image, save it on SDcard if want to, take an id through content provider, display it in dialog box with ok/cancel button. – Puppy

Answer 1

Here's an example activity that will launch the camera app and then retrieve the image and display it.

package edu.gvsu.cis.masl.camerademo;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class MyCameraActivity extends Activity {
    private static final int CAMERA_REQUEST = 1888; 
    private ImageView imageView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        this.imageView = (ImageView)this.findViewById(R.id.imageView1);
        Button photoButton = (Button) this.findViewById(R.id.button1);
        photoButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                startActivityForResult(cameraIntent, CAMERA_REQUEST); 
            }
        });
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
        if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);
        }  
    } 
}

Note that the camera app itself gives you the ability to review/retake the image, and once an image is accepted, the activity displays it.

Here is the layout that the above activity uses. It is simply a LinearLayout containing a Button with id button1 and an ImageView with id imageview1:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/photo"></Button>
    <ImageView android:id="@+id/imageView1" android:layout_height="wrap_content" android:src="@drawable/icon" android:layout_width="wrap_content"></ImageView>

</LinearLayout>

And one final detail, be sure to add:

<uses-feature android:name="android.hardware.camera"></uses-feature> 

and if camera is optional to your app functionality. make sure to set require to false in the permission. like this

<uses-feature android:name="android.hardware.camera" android:required="false"></uses-feature>

to your manifest.xml.

Bitmap photo = (Bitmap) data.getExtras().get("data"); Its giving a Null pointer expection. When i open the app and click Capture.. it goes to the camera app and after 2-4 secs the whole thing crashes. – Ulceration

I suppose to be on the safe side we should be checking to see if resultCode == Activity.RESULT_OK in the onActivityResult() method. As to why the camera is crashing, we'd have to see a stack trace. – Rolfston

@Harsha M V This is a known bug on Samsung Galaxy. Please see this answer #7031874 – Dieter

This link developer.android.com/reference/android/hardware/Camera.html states it also needs <uses-permission android:name="android.permission.CAMERA" />. I can understand it needs that permission, however does it really need the <uses-feature>s? I imagine the Play Store would filter out devices with no camera when u use those, however what if using the camera in your app is optional? You would lose a lot of potential users if it does filters out devices with no camera. – Tiptop

@WillKru if the feature is not mandatory, you should add the <uses-feature/> with the android:required="false" attribute: <uses-feature android:name="android.hardware.camera" android:required="false"></uses-feature> – Pronoun

@Mannaz hey can u tell me how to open both camrea and galerry in onclick?i have done but dont view both of at one popup.have u any idea ? – Yap

@Rolfston onActivityResult is not getting called...? i am using your code first it was calling but next day i tried since then onActivityResult is not calling... – Macrophage

data gives only thumbnail image – Toothwort

FAIL - it takes image but it does not show the image correctly like it gets flipped or inverted or rotated. – Crescent

I was wondering whether anybody could expand on this answer. Thanks for what is posted originally as that is great. Although I want a way to be able to have a way to constantly save any image taken using the Camera Intent in my app. I want to display them in a GridView. Currently, when I close the app and re-open it, the images all disappear! Thanks in advance. Even a post to an answer or tutorial would be helpful! – Monocoque

@Rolfston i had used this code it capturing image and displaing propertly but it will cause other problem that it will remove old data from other control like i had selected in spinter then it will recreate activity and clear all data. can you check it? – Gena

Looks like data is also null on Nexus 4 devices, possibly other Google devices as well. – Two

Also note that Bitmap photo = (Bitmap) data.getExtras().get("data"); does not grab the image that was taken. It grabs a thumbnail of the image that was taken. – Ligni

Works perfect, how could you enable cropping so it has to be square before it returns to the app? – Unriddle

Works perfectly - also with fragments – Torsibility

@BillyCoover, do you know a way on displaying the actual image instead of just the thumbnail? Thanks – Barca

Thanks for the answer. One more question, in your code example you use the package edu.gvsu.cis.masl.camerademo, I tried to do the same, but in my case IDE doesn't recognize it. Hence, how can I add this package to SDK/IDE? – Diffractometer

It working fine. But how to capture high resolution image? – Orelia

android.hardware.camera is now deprecated – Iterative

App crashes when you press X on Camera – Brainbrainard

This answer is incorrect. It captures low resolution thumbnail, not the actual photo. – Pall

You need this permission too <uses-permission android:name="android.permission.CAMERA" /> – Syconium

To check all permission needed I suggest you to check this page: link – Botsford

If you want to save the actual image from the camera use Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); Uri uriSavedImage=Uri.fromFile(new File("/sdcard/flashCropped.png")); camera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage); startActivityForResult(camera, 1); you need to save the file first in your app media storage then you can able to save actual image. – Weir

Answer 2

Update (2020)

Google has added a new ActivityResultRegistry API that "lets you handle the startActivityForResult() + onActivityResult() as well as requestPermissions() + onRequestPermissionsResult() flows without overriding methods in your Activity or Fragment, brings increased type safety via ActivityResultContract, and provides hooks for testing these flows" - source.

The API was added in androidx.activity 1.2.0-alpha02 and androidx.fragment 1.3.0-alpha02.

So you are now able to do something like:

val takePicture = registerForActivityResult(ActivityResultContracts.TakePicture()) { success: Boolean ->
    if (success) {
        // The image was saved into the given Uri -> do something with it
    }
}

val imageUri: Uri = ...
button.setOnClickListener {
    takePicture.launch(imageUri)
}

Take a look at the documentation to learn how to use the new Activity result API: https://developer.android.com/training/basics/intents/result#kotlin

There are many built-in ActivityResultContracts that allow you to do different things like pick contacts, request permissions, take pictures or take videos. You are probably interested in the ActivityResultContracts.TakePicture shown above.

Note that androidx.fragment 1.3.0-alpha04 deprecates the startActivityForResult() + onActivityResult() and requestPermissions() + onRequestPermissionsResult() APIs on Fragment. Hence it seems that ActivityResultContracts is the new way to do things from now on.

Original answer (2015)

It took me some hours to get this working. The code it's almost a copy-paste from developer.android.com, with a minor difference.

Request this permission on the AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

On your Activity, start by defining this:

static final int REQUEST_IMAGE_CAPTURE = 1;
private Bitmap mImageBitmap;
private String mCurrentPhotoPath;
private ImageView mImageView;

Then fire this Intent in an onClick:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getPackageManager()) != null) {
    // Create the File where the photo should go
    File photoFile = null;
    try {
        photoFile = createImageFile();
    } catch (IOException ex) {
        // Error occurred while creating the File
        Log.i(TAG, "IOException");
    }
    // Continue only if the File was successfully created
    if (photoFile != null) {
        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
        startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE);
    }
}

Add the following support method:

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  // prefix
            ".jpg",         // suffix
            storageDir      // directory
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = "file:" + image.getAbsolutePath();
    return image;
}

Then receive the result:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        try {
            mImageBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath));
            mImageView.setImageBitmap(mImageBitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

What made it work is the MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath)), which is different from the code from developer.android.com. The original code gave me a FileNotFoundException.

Jolson

"Uri.parse(mCurrentPhotoPath))" is the solution since MediaStore.EXTRA_OUTPUT leads to null intent result. – Pris

My picture is coming in landscape mode by default, am I missing anything? – Vantage

I am using this in a FragmentDialog and it crashes on this line: startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE); with this error:java.lang.SecurityException: Permission Denial: starting Intent { act=android.media.action.IMAGE_CAPTURE flg=0x3 cmp=com.lge.camera/.app.CameraActivity clip={text/uri-list U:file:///storage/emulated/0/Pictures/JPEG_20170721_040943_-644534083.jpg} (has extras) } from ProcessRecord{65edf85 19134:com.devhopes.ryde/u0a151} (pid=19134, uid=10151) with revoked permission android.permission.CAMERA - when I click on the image view – Counterirritant

@Counterirritant you need to request permissions to use the camera on Android 6.0 and above. – Jolson

@AlbertVilaCalvo other than adding them to AndroidManifest, how can I do that? – Counterirritant

@Counterirritant you have to request permissions at run time. It's explained in the official documentation: developer.android.com/training/permissions/requesting.html – Jolson

Great to see that you followed Android recommendations. – Butterfish

This code didn't work for me. I receive android.os.FileUriExposedException: file:///storage/emulated/0/Pictures/JPEG_20180823_102340_722874009725833047.jpg exposed beyond app through ClipData.Item.getUri(). Any idea on how to fix this? @AlbertVilaCalvo – Premiere

@RobertGomez you can no longer use file: Uri values in many places. See this blog post from Mark Murphy: commonsware.com/blog/2016/03/14/… – Jolson

@AlbertVilaCalvo I didn't know that. So, do you have any idea about how to fix this? I don't know what can I change. I hope you can help me, thanks. – Premiere

I had to use storageDir = Context.getFilesDir(); in place of File storageDir = Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_PICTURES);. Otherwise I was getting a permission denied error. – Substantialism

Struggled a long time before i saw "file:" in the path. Thanks for the answer! :) – Haro

You need to add storage permission for API 23+ even if you have added permission in Manifest. https://mcmap.net/q/100378/-permission-denied-when-creating-new-file-on-external-storage – Handout

This updated answer is just valid to Kotlin? I can't find Java example – Rebutter

startActivityForResult is deprecated – Supination

This is a great solution if you do not need a Camera permission in any other part of the app. If you add CAMERA permission in manifest. This will not work. Atleast, I could not get it working as of today. I needed CAMERA permission for MLKit barcode analysis too for example. – Misestimate

@AlbertVilaCalvo #48118011 instead of Uri.fromFile(photoFile) use FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".provider", photoFile) – Popovich

@ Amit Garg mImageBitmap = rotateBitmap(mImageBitmap, 90); – Popovich

ResultCode == 1 inside ResultCode == RESULT_OK ? – Spoonful

It's requestCode==1, helps identify who initiated the request. – Teresita

Answer 4

I know it's a quite old thread, but all these solutions are not completed and don't work on some devices when user rotates camera because data in onActivityResult is null. So here is solution which I have tested on lots of devices and haven't faced any problem so far.

First declare your Uri variable in your activity:

private Uri uriFilePath;

Then create your temporary folder for storing captured image and make intent for capturing image by camera:

PackageManager packageManager = getActivity().getPackageManager();
if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
    File mainDirectory = new File(Environment.getExternalStorageDirectory(), "MyFolder/tmp");
         if (!mainDirectory.exists())
             mainDirectory.mkdirs();

          Calendar calendar = Calendar.getInstance();

          uriFilePath = Uri.fromFile(new File(mainDirectory, "IMG_" + calendar.getTimeInMillis()));
          intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
          intent.putExtra(MediaStore.EXTRA_OUTPUT, uriFilePath);
          startActivityForResult(intent, 1);
}

And now here comes one of the most important things, you have to save your uriFilePath in onSaveInstanceState, because if you didn't do that and user rotated his device while using camera, your uri would be null.

@Override
protected void onSaveInstanceState(Bundle outState) {
     if (uriFilePath != null)
         outState.putString("uri_file_path", uriFilePath.toString());
     super.onSaveInstanceState(outState);
}

After that you should always recover your uri in your onCreate method:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (savedInstanceState != null) {
         if (uriFilePath == null && savedInstanceState.getString("uri_file_path") != null) {
             uriFilePath = Uri.parse(savedInstanceState.getString("uri_file_path"));
         }
    } 
}

And here comes last part to get your Uri in onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {    
    if (resultCode == RESULT_OK) {
         if (requestCode == 1) {
            String filePath = uriFilePath.getPath(); // Here is path of your captured image, so you can create bitmap from it, etc.
         }
    }
 }

P.S. Don't forget to add permissions for Camera and Ext. storage writing to your Manifest.

I am working with a FragmentDialog. I tried to do this as you have.. I declared the Uri, then in a method "storeCapturedImage"- I put in the PackageManager code, then I added on onSaveInstanceState() - all of these before the onCreate. Then in the onCreateDialog, I placed the 'recover your uri' code, and then the onActivityResult was placed just above the onCreate method... see next comment for what I put after the 'recover your uri' code – Counterirritant

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); LayoutInflater inflater = getActivity().getLayoutInflater(); View dialogView = inflater.inflate(R.layout.username_dialog, null); ImageView profilePic = dialogView.findViewById(R.id.profile_pic); profilePic.setImageResource(R.drawable.user_placeholder); profilePic.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { storeCapturedImage();} }); builder.setView(dialogView); – Counterirritant

I really wonder why the OS doesn't send you the uri in the intent inside of OnActivityResult. I hope there is a good reason, because carrying state around is always not a good thing to do IMO. – Bluebonnet

so what's the use of data in onActivityResult callback? – Billon

Answer 5

Here you can open camera or gallery and set the selected image into imageview

private static final String IMAGE_DIRECTORY = "/YourDirectName";
private Context mContext;
private CircleImageView circleImageView;  // imageview
private int GALLERY = 1, CAMERA = 2;

Add permissions in manifest

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="ANDROID.PERMISSION.READ_EXTERNAL_STORAGE" />

In onCreate()

    requestMultiplePermissions(); // check permission 

    circleImageView = findViewById(R.id.profile_image);
    circleImageView.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            showPictureDialog();
        }
    });

Show options dialog box (to select image from camera or gallery)

private void showPictureDialog() {
    AlertDialog.Builder pictureDialog = new AlertDialog.Builder(this);
    pictureDialog.setTitle("Select Action");
    String[] pictureDialogItems = {"Select photo from gallery", "Capture photo from camera"};
    pictureDialog.setItems(pictureDialogItems,
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    switch (which) {
                        case 0:
                            choosePhotoFromGallary();
                            break;
                        case 1:
                            takePhotoFromCamera();
                            break;
                    }
                }
            });
    pictureDialog.show();
}

Get photo from Gallery

public void choosePhotoFromGallary() {
    Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(galleryIntent, GALLERY);
}

Get photo from Camera

private void takePhotoFromCamera() {
    Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, CAMERA);
}

Once the image is get selected or captured then ,

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == this.RESULT_CANCELED) {
        return;
    }
    if (requestCode == GALLERY) {
        if (data != null) {
            Uri contentURI = data.getData();
            try {
                Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), contentURI);
                String path = saveImage(bitmap);
                Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show();
                circleImageView.setImageBitmap(bitmap);

            } catch (IOException e) {
                e.printStackTrace();
                Toast.makeText(getApplicationContext(), "Failed!", Toast.LENGTH_SHORT).show();
            }
        }

    } else if (requestCode == CAMERA) {
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
        circleImageView.setImageBitmap(thumbnail);
        saveImage(thumbnail);
        Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show();
    }
}

Now its time to store the picture

public String saveImage(Bitmap myBitmap) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    myBitmap.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
    File wallpaperDirectory = new File(Environment.getExternalStorageDirectory() + IMAGE_DIRECTORY);
    if (!wallpaperDirectory.exists()) {  // have the object build the directory structure, if needed.
        wallpaperDirectory.mkdirs();
    }

    try {
        File f = new File(wallpaperDirectory, Calendar.getInstance().getTimeInMillis() + ".jpg");
        f.createNewFile();
        FileOutputStream fo = new FileOutputStream(f);
        fo.write(bytes.toByteArray());
        MediaScannerConnection.scanFile(this,
                new String[]{f.getPath()},
                new String[]{"image/jpeg"}, null);
        fo.close();
        Log.d("TAG", "File Saved::--->" + f.getAbsolutePath());

        return f.getAbsolutePath();
    } catch (IOException e1) {
        e1.printStackTrace();
    }
    return "";
}

Request permission

    private void requestMultiplePermissions() {
    Dexter.withActivity(this)
            .withPermissions(
                    Manifest.permission.CAMERA,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE,
                    Manifest.permission.READ_EXTERNAL_STORAGE)
            .withListener(new MultiplePermissionsListener() {
                @Override
                public void onPermissionsChecked(MultiplePermissionsReport report) {
                    if (report.areAllPermissionsGranted()) {  // check if all permissions are granted
                        Toast.makeText(getApplicationContext(), "All permissions are granted by user!", Toast.LENGTH_SHORT).show();
                    }

                    if (report.isAnyPermissionPermanentlyDenied()) { // check for permanent denial of any permission
                        // show alert dialog navigating to Settings
                        //openSettingsDialog();
                    }
                }

                @Override
                public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
                    token.continuePermissionRequest();
                }
            }).
            withErrorListener(new PermissionRequestErrorListener() {
                @Override
                public void onError(DexterError error) {
                    Toast.makeText(getApplicationContext(), "Some Error! ", Toast.LENGTH_SHORT).show();
                }
            })
            .onSameThread()
            .check();
}

startActivityForResult is deprecated – Supination

Answer 6

You need to read up about the Camera. (I think to do what you want, you'd have to save the current image to your app, do the select/delete there, and then recall the camera to try again, rather than doing the retry directly inside the camera.)

Grudging

Answer 7

Here is code I have used for Capturing and Saving Camera Image then display it to imageview. You can use according to your need.

You have to save Camera image to specific location then fetch from that location then convert it to byte-array.

Here is method for opening capturing camera image activity.

private static final int CAMERA_PHOTO = 111;
private Uri imageToUploadUri;

private void captureCameraImage() {
        Intent chooserIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        File f = new File(Environment.getExternalStorageDirectory(), "POST_IMAGE.jpg");
        chooserIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
        imageToUploadUri = Uri.fromFile(f);
        startActivityForResult(chooserIntent, CAMERA_PHOTO);
    }

then your onActivityResult() method should be like this.

@Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);

            if (requestCode == CAMERA_PHOTO && resultCode == Activity.RESULT_OK) {
                if(imageToUploadUri != null){
                    Uri selectedImage = imageToUploadUri;
                    getContentResolver().notifyChange(selectedImage, null);
                    Bitmap reducedSizeBitmap = getBitmap(imageToUploadUri.getPath());
                    if(reducedSizeBitmap != null){
                        ImgPhoto.setImageBitmap(reducedSizeBitmap);
                        Button uploadImageButton = (Button) findViewById(R.id.uploadUserImageButton);
                          uploadImageButton.setVisibility(View.VISIBLE);                
                    }else{
                        Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
                    }
                }else{
                    Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
                }
            } 
        }

Here is getBitmap() method used in onActivityResult(). I have done all performance improvement that can be possible while getting camera capture image bitmap.

private Bitmap getBitmap(String path) {

        Uri uri = Uri.fromFile(new File(path));
        InputStream in = null;
        try {
            final int IMAGE_MAX_SIZE = 1200000; // 1.2MP
            in = getContentResolver().openInputStream(uri);

            // Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(in, null, o);
            in.close();


            int scale = 1;
            while ((o.outWidth * o.outHeight) * (1 / Math.pow(scale, 2)) >
                    IMAGE_MAX_SIZE) {
                scale++;
            }
            Log.d("", "scale = " + scale + ", orig-width: " + o.outWidth + ", orig-height: " + o.outHeight);

            Bitmap b = null;
            in = getContentResolver().openInputStream(uri);
            if (scale > 1) {
                scale--;
                // scale to max possible inSampleSize that still yields an image
                // larger than target
                o = new BitmapFactory.Options();
                o.inSampleSize = scale;
                b = BitmapFactory.decodeStream(in, null, o);

                // resize to desired dimensions
                int height = b.getHeight();
                int width = b.getWidth();
                Log.d("", "1th scale operation dimenions - width: " + width + ", height: " + height);

                double y = Math.sqrt(IMAGE_MAX_SIZE
                        / (((double) width) / height));
                double x = (y / height) * width;

                Bitmap scaledBitmap = Bitmap.createScaledBitmap(b, (int) x,
                        (int) y, true);
                b.recycle();
                b = scaledBitmap;

                System.gc();
            } else {
                b = BitmapFactory.decodeStream(in);
            }
            in.close();

            Log.d("", "bitmap size - width: " + b.getWidth() + ", height: " +
                    b.getHeight());
            return b;
        } catch (IOException e) {
            Log.e("", e.getMessage(), e);
            return null;
        }
    }

Hope it helps!

This is pretty old but I like the way you did this. When I choose from gallery, the image fails to display though. Any thoughts? – Prodigy

Answer 9

I created a dialog with the option to choose Image from gallery or camera. with a callback as

• Uri if the image is from the gallery
• String as a file path if the image is captured from the camera.
• Image as File the image chosen from camera needs to be uploaded on the internet as Multipart file data

At first we to define permission in AndroidManifest as we need to write external store while creating a file and reading images from gallery

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Create a file_paths xml in app/src/main/res/xml/file_paths.xml

with path

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

Then we need to define file provier to generate Content uri to access file stored in external storage

<provider
    android:name="androidx.core.content.FileProvider"
    android:authorities="${applicationId}.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Answer 10

As others have discussed, using data.getExtras().get("data") will just get the low-quality thumbnail.

The solution is to pass a location with your ACTION_IMAGE_CAPTURE intent telling the camera where to store the full quality image.

The code is Kotlin and does not need any permissions.

---

val f = File("${getExternalFilesDir(null)}/imgShot")
val photoURI = FileProvider.getUriForFile(this, "${packageName}.fileprovider", f)
val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
        .apply { putExtra(MediaStore.EXTRA_OUTPUT, photoURI) }
startActivityForResult(intent, 1234)

Then handle the result after the picture was taken:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    if (requestCode == 1234 && resultCode == Activity.RESULT_OK) {
        val bitmap = BitmapFactory.decodeFile(
                File("${getExternalFilesDir(null)}/imgShot").toString()
        )
        // use imageView.setImageBitmap(bitmap) or whatever
    }
}

---

You will also need to add an external FileProvider as described here. AndroidManifest.xml:

<manifest>
    <application>

        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provide_paths" />
        </provider>

    </application>
</manifest>

Add a new file app/src/main/res/xml/provide_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path name="external_files" path="." />
</paths>

Lastly you should replace 1234 with your own logic for keeping track of request code (usually an enum with a member such as RequestCode.CAPTURE_IMAGE)

Answer 14

2021 May, JAVA

after handling necessary Permissions described next to this post, in manifest add:

<uses-permission 
    android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission 
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:maxSdkVersion="18"  />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />
....

    <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>
....

where ${applicationId} is app's package name , e.g. my.app.com.

In res->xml->provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
 <paths>
  <external-files-path name="my_images" path="Pictures" />
  <external-path name="external_files" path="."/>
    <files-path
    name="files"   path="." />
    <external-cache-path
      name="images" path="." />
 </paths>

in Activity:

private void onClickCaptureButton(View view) {
    Intent takePictureIntent_ = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent_.resolveActivity(getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile_ = null;
        try {
            photoFile_ = createImageFile();
        } catch (IOException ex) {
        }
        if(photoFile_!=null){
            picturePath=photoFile_.getAbsolutePath();
        }
        // Continue only if the File was successfully created
        if (photoFile_ != null) {
            Uri photoURI_ = FileProvider.getUriForFile(this,
               "my.app.com.fileprovider", photoFile_);
            takePictureIntent_.putExtra(MediaStore.EXTRA_OUTPUT, photoURI_);
            startActivityForResult(takePictureIntent_, REQUEST_IMAGE_CAPTURE);
        }
    }
}

And three more moves:

...
private static String picturePath;
private static final int REQUEST_IMAGE_CAPTURE = 2;
...
private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp_ = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new 
      Date());
    String imageFileName_ = "JPEG_" + timeStamp_ + "_";
    File storageDir_ = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image_ = File.createTempFile(
            imageFileName_,  /* prefix */
            ".jpg",         /* suffix */
            storageDir_      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    picturePath= image_.getAbsolutePath();
    return image_;
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
   if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK 
   ){

        try {
            File file_ = new File(picturePath);
            Uri uri_ = FileProvider.getUriForFile(this,
                    "my.app.com.fileprovider", file_);
            rasm.setImageURI(uri_);
        } catch (/*IO*/Exception e) {
            e.printStackTrace();
        }
    }
}

and

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putString("safar", picturePath);
    // Always call the superclass so it can save the view hierarchy state
    super.onSaveInstanceState(savedInstanceState);
}

and:

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (savedInstanceState != null) {
        picturePath = savedInstanceState.getString("safar");
    }
 ....
}

Please, follow this example with this implementation by using Kotlin and Andoirdx support:

button1.setOnClickListener{
        file = getPhotoFile()
        val uri: Uri = FileProvider.getUriForFile(applicationContext, "com.example.foto_2.filrprovider", file!!)
        captureImage.putExtra(MediaStore.EXTRA_OUTPUT, uri)

        val camaraActivities: List<ResolveInfo> = applicationContext.getPackageManager().queryIntentActivities(captureImage, PackageManager.MATCH_DEFAULT_ONLY)

        for (activity in camaraActivities) {
            applicationContext.grantUriPermission(activity.activityInfo.packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
        }

        startActivityForResult(captureImage, REQUEST_PHOTO)
    }

And the activity result:

if (requestCode == REQUEST_PHOTO) {
        val uri = FileProvider.getUriForFile(applicationContext, "com.example.foto_2.filrprovider", file!!)
        applicationContext.revokeUriPermission(uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
        imageView1.viewTreeObserver.addOnGlobalLayoutListener {
            width = imageView1.width
            height = imageView1.height
            imageView1.setImageBitmap(getScaleBitmap(file!!.path , width , height))
        }
        if(width!=0&&height!=0){
            imageView1.setImageBitmap(getScaleBitmap(file!!.path , width , height))
        }else{
            val size = Point()
            this.windowManager.defaultDisplay.getSize(size)
            imageView1.setImageBitmap(getScaleBitmap(file!!.path , size.x , size.y))
        }

    }

Bad quality

From my experience if we use

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, RESULT_ADD_PHOTO);

And handle in onActivityResult() with

Bitmap thumbnail= (Bitmap) data.getExtras().get("data");

It will give you thumbnail only and of course have a bad quality.

Nice quality

You can show camera and save your image file in public directory, example in Document directory

Use this in your onClick()

String imagePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS) +
                File.separator + "your_image_name.jpeg";
Intent i =new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageFile = new File(imagePath );
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(imageFile));
startActivityForResult(i, RESULT_ADD_PHOTO);

And in onActivityResult()

Bitmap imageBitmap1 = BitmapFactory.decodeFile(imageFile.getAbsolutePath());
Matrix matrix = new Matrix();
matrix.postRotate(90);
Bitmap imageBitmap = Bitmap.createBitmap(imageBitmap1, 0, 0, imageBitmap1.getWidth(), imageBitmap1.getHeight(), matrix, true);
binding.imageView.setImageBitmap(imageBitmap);

I use postRotate() because in my code, image result rotate to left so I need to rotate it 90

Bitmap coming as null in activity result, i have followed all steps given here. am i missing anything? – Rockyrococo

Capture Image For Kotlin

Step 1 : Add Camera Permission

Step 2 : Reusable Kotlin Extension Function Usage

fun Activity.dispatchTakePictureIntent(REQUEST_IMAGE_CAPTURE: Int = 313, photoFileCallback: (file: File) -> Unit = {}) {
        Intent(MediaStore.ACTION_IMAGE_CAPTURE).also { takePictureIntent ->
            // Ensure that there's a camera activity to handle the intent
            takePictureIntent.resolveActivity(packageManager)?.also {
                // Create the File where the photo should go
                val photoFile: File? = try {
                    createImageFile()
                } catch (ex: IOException) {
                    // Error occurred while creating the File
                    null
                }
    
                // Continue only if the File was successfully created
                photoFile?.also {
                    photoFileCallback(it)
                    val photoURI: Uri = FileProvider.getUriForFile(
                            this,
                            packageName,
                            it
                    )
                    takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI)
                    startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE)
                }
            }
        }
