android camera : Failure delivering result ResultInfo{who=null, request=0, result=-1, data=null} to activity

Question

i've really frustased to solve my problem, i have an application that using camera, when camera capture a photo, it will display on activity, when i'm not using cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri); photo will display on activity, but the name and path file is not like what i wanted. i'm using galaxy tab for compiling it, i have follow tutorial to solve my problem from here , here and here but my application still force close and eror, this is my code :

{
    File sdCard = Environment.getExternalStorageDirectory();
    File path = new File (sdCard.getAbsolutePath() + "/android/data/spaj_foto");
    path.mkdir();
    File file = new File (path,"spaj_foto.png");
    String filePath ="/android/data/spaj_foto/spaj_foto.png";

    try {
        file.createNewFile();
    } catch (IOException e) {}       


    mPhotoUri = Uri.fromFile(file); 
    values.put(MediaStore.Images.ImageColumns.DATA, file.getPath());
    mPhotoUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri);
    startActivityForResult(cameraIntent,TAKE_PHOTO_CODE );  

}

activityresult method :

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
        image_spaj.setImageBitmap(photo);


        // CALL THIS METHOD TO GET THE URI FROM THE BITMAP
        Uri tempUri = getImageUri(getApplicationContext(), photo);

        // CALL THIS METHOD TO GET THE ACTUAL PATH
        File finalFile = new File(getRealPathFromURI(tempUri));

//              System.out.println(mImageCaptureUri);
    }  
}
public String getRealPathFromURI(Uri mPhotoUri) {
    Cursor cursor = getContentResolver().query(mPhotoUri, null, null, null, null); 
    cursor.moveToFirst(); 
    int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
    return cursor.getString(idx); 
}

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

this is my logcat says:

i really hope someone can help me to solve my problem, i already stack and can't thinking anyway again, please someone help me... thank you.

This is just a null pointer exception, what is the line FormSpaj.java:993? – Concessionaire

Bitmap photo = (Bitmap) data.getExtras().get("data"); – Araucania

getExtras() can return null if there is no extras Bundle. You should make sure the value returned from getExtras() isn't null. – Injury

my image is saved on my path that i wanted, i have no idea, why is this getting null – Araucania

Also, you're setting the Extras with the "key" MediaStore.EXTRA_OUTPUT, but attempting to get the key data -- are you sure they are equal? Edit: They're not. MediaStore.EXTRA_OUTPUT == "output". – Injury

i think like that, is that false? – Araucania

If you store the value with the "key" MediaStore.EXTRA_OUTPUT, you'll of course want to fetch it using the same key, but definitely not "data". – Injury

@AoyamaNanami android:configChanges="orientation|keyboardHidden|screenSize" add the configChanges for particular activity. Yesterday i had same problem. after add that configChanges its working fine. try it – Sideswipe

android:configChanges is affected to camera result image ? i did not understand, can yo please explain it ? – Quickel

Answer 1

Make sure you have both Camera Permission and READ/WRITE External Storage Permissions.

Try this is working like charm with me

private String selectedImagePath = "";
    final private int PICK_IMAGE = 1;
    final private int CAPTURE_IMAGE = 2;

public Uri setImageUri() {
        // Store image in dcim
        File file = new File(Environment.getExternalStorageDirectory() + "/DCIM/", "image" + new Date().getTime() + ".png");
        Uri imgUri = Uri.fromFile(file);
        this.imgPath = file.getAbsolutePath();
        return imgUri;
    }


    public String getImagePath() {
        return imgPath;

thank you for your help... but i have one question, why when i capture another image, this is not rewrite the image that have created before? – Araucania

because we generate unique uri in this method setImageUri() by appending current time milliseconds. If you want to overwrite the file give static hard coded file name in setImageUri() method. – Allanite

i have made like this : File file = new File(Environment.getExternalStorageDirectory() +"/android/data/spaj_foto/spaj_foto.png"); Uri imgUri = Uri.fromFile(file); this.imgPath = file.getAbsolutePath(); – Araucania

This will not work like a charm for the Android version running above Android N, only working for the Android Versions below N – Ares

Answer 2

Try this, Yesterday i had same problem. using below code i rectify problem. just try on it.

Note : And also add configChanges for particular activity. while calling the camera intent activity will be refreshed. you need to avoid that. android:configChanges="orientation|keyboardHidden|screenSize"

btnGallery.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
           intent = new Intent(Intent.ACTION_PICK);

                            startActivityForResult(intent, 1);
        }
    });

    btnCapture.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

Answer 3

I think following line causes the issue.

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

You pass the file uri already as following

cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri);

When you pass EXTRA_OUTPUT with a URI, the intent you receive in onActivityResult() will be null. If you want to get image in this method, fetch image with the path you pass with EXTRA_OUTPUT.

This really works. I started facing crash issue on Android 7.0 and removing this line did the trick. Also removing this line didn't affect pre-nougat devices as well. Tested from Android 4.4 and above. – Boneblack
