How to save an image in Android Q using MediaStore?

Question

Here is a link to the new Android Q Scoped Storage.

According to this Android Developers Best Practices Blog, storing shared media files (which is my case) should be done using the MediaStore API.

Digging into the docs and I cannot find a relevant function.

Here is my trial in Kotlin:

val bitmap = getImageBitmap() // I have a bitmap from a function or callback or whatever
val name = "example.png" // I have a name

val picturesDirectory = getExternalFilesDir(Environment.DIRECTORY_PICTURES)!!

// Make sure the directory "Android/data/com.mypackage.etc/files/Pictures" exists
if (!picturesDirectory.exists()) {
    picturesDirectory.mkdirs()
}

try {
    val out = FileOutputStream(File(picturesDirectory, name))
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, out)

    out.flush()
    out.close()

} catch(e: Exception) {
    // handle the error
}

The result is that my image is saved here Android/data/com.mypackage.etc/files/Pictures/example.png as described in the Best Practices Blog as Storing app-internal files

My question is:

How to save an image using the MediaStore API? Answers in Java are equally acceptable.

---

EDIT

But there are 3 more points.

Here is my code:

val name = "Myimage"
val relativeLocation = Environment.DIRECTORY_PICTURES + File.pathSeparator + "AppName"

val contentValues  = ContentValues().apply {
    put(MediaStore.Images.ImageColumns.DISPLAY_NAME, name)
    put(MediaStore.MediaColumns.MIME_TYPE, "image/png")

    // without this part causes "Failed to create new MediaStore record" exception to be invoked (uri is null below)
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        put(MediaStore.Images.ImageColumns.RELATIVE_PATH, relativeLocation)
    }
}

val contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI
var stream: OutputStream? = null
var uri: Uri? = null

try {
    uri = contentResolver.insert(contentUri, contentValues)
    if (uri == null)
    {
        throw IOException("Failed to create new MediaStore record.")
    }

    stream = contentResolver.openOutputStream(uri)

    if (stream == null)
    {
        throw IOException("Failed to get output stream.")
    }

    if (!bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream))
    {
        throw IOException("Failed to save bitmap.")
    }


    Snackbar.make(mCoordinator, R.string.image_saved_success, Snackbar.LENGTH_INDEFINITE).setAction("Open") {
        val intent = Intent()
        intent.type = "image/*"
        intent.action = Intent.ACTION_VIEW
        intent.data = contentUri
        startActivity(Intent.createChooser(intent, "Select Gallery App"))
    }.show()

} catch(e: IOException) {
    if (uri != null)
    {
        contentResolver.delete(uri, null, null)
    }

    throw IOException(e)

}
finally {
    stream?.close()
}

1- The image saved doesn't get its correct name "Myimage.png"

I tried using "Myimage" and "Myimage.PNG" but neither worked.

The image always gets a name made up of numbers like:

1563468625314.jpg

Which bring us to the second problem:

2- The image is saved as jpg even though I compress the bitmap in the format of png.

Not a big issue. Just curious why.

3- The relativeLocation bit causes an exception on Devices less than Android Q. After surrounding with the "Android Version Check" if statement, the images are saved directly in the root of the Pictures folder.

EDIT 2

Changed to:

uri = contentResolver.insert(contentUri, contentValues)
if (uri == null)
{
    throw IOException("Failed to create new MediaStore record.")
}

val cursor = contentResolver.query(uri, null, null, null, null)
DatabaseUtils.dumpCursor(cursor)
cursor!!.close()

stream = contentResolver.openOutputStream(uri)

Here are the logs

I noticed the title to be matching the name so I tried adding:

put(MediaStore.Images.ImageColumns.TITLE, name)

It still didn't work and here are the new logs:

And I can't change date_added to a name.

And MediaStore.MediaColumns.DATA is deprecated.

Answer 1

Try the next method. Android Q (and above) already takes care of creating the folders if they don’t exist. The example is hard-coded to output into the DCIM folder. If you need a sub-folder then append the sub-folder name as next:

final String relativeLocation = Environment.DIRECTORY_DCIM + File.separator + “YourSubforderName”;

Consider that the compress format should be related to the mime-type parameter. For example, with a JPEG compress format the mime-type would be "image/jpeg", and so on. Probably you may also want to pass the compress quality as a parameter, in this example is hardcoded to 95.

Java:

@NonNull
public Uri saveBitmap(@NonNull final Context context, @NonNull final Bitmap bitmap,
                      @NonNull final Bitmap.CompressFormat format,
                      @NonNull final String mimeType,
                      @NonNull final String displayName) throws IOException {

    final ContentValues values = new ContentValues();
    values.put(MediaStore.MediaColumns.DISPLAY_NAME, displayName);
    values.put(MediaStore.MediaColumns.MIME_TYPE, mimeType);
    values.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_DCIM);

    final ContentResolver resolver = context.getContentResolver();
    Uri uri = null;

    try {
        final Uri contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
        uri = resolver.insert(contentUri, values);

        if (uri == null)
            throw new IOException("Failed to create new MediaStore record.");

        try (final OutputStream stream = resolver.openOutputStream(uri)) {
            if (stream == null)
                throw new IOException("Failed to open output stream.");
         
            if (!bitmap.compress(format, 95, stream))
                throw new IOException("Failed to save bitmap.");
        }

        return uri;
    }
    catch (IOException e) {

        if (uri != null) {
            // Don't leave an orphan entry in the MediaStore
            resolver.delete(uri, null, null);
        }

        throw e;
    }
}

Kotlin:

@Throws(IOException::class)
fun saveBitmap(
    context: Context, bitmap: Bitmap, format: Bitmap.CompressFormat,
    mimeType: String, displayName: String
): Uri {

    val values = ContentValues().apply {
        put(MediaStore.MediaColumns.DISPLAY_NAME, displayName)
        put(MediaStore.MediaColumns.MIME_TYPE, mimeType)
        put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_DCIM)
    }

    val resolver = context.contentResolver
    var uri: Uri? = null

    try {
        uri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values)
            ?: throw IOException("Failed to create new MediaStore record.")

        resolver.openOutputStream(uri)?.use {
            if (!bitmap.compress(format, 95, it))
                throw IOException("Failed to save bitmap.")
        } ?: throw IOException("Failed to open output stream.")

        return uri

    } catch (e: IOException) {

        uri?.let { orphanUri ->
            // Don't leave an orphan entry in the MediaStore
            resolver.delete(orphanUri, null, null)
        }

        throw e
    }
}

Kotlin variant, with a more functional style:

@Throws(IOException::class)
fun saveBitmap(
    context: Context, bitmap: Bitmap, format: Bitmap.CompressFormat,
    mimeType: String, displayName: String
): Uri {

    val values = ContentValues().apply {
        put(MediaStore.MediaColumns.DISPLAY_NAME, displayName)
        put(MediaStore.MediaColumns.MIME_TYPE, mimeType)
        put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_DCIM)
    }

    var uri: Uri? = null

    return runCatching {
        with(context.contentResolver) {
            insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values)?.also {
                uri = it // Keep uri reference so it can be removed on failure

                openOutputStream(it)?.use { stream ->
                    if (!bitmap.compress(format, 95, stream))
                        throw IOException("Failed to save bitmap.")
                } ?: throw IOException("Failed to open output stream.")

            } ?: throw IOException("Failed to create new MediaStore record.")
        }
    }.getOrElse {
        uri?.let { orphanUri ->
            // Don't leave an orphan entry in the MediaStore
            context.contentResolver.delete(orphanUri, null, null)
        }

        throw it
    }
}

Thank you very much, that really helped, but there are 3 more points. Please check my edited question – Entrammel

Is this problem happening only in Android Q, or all Android versions? Take into account that the code in my answer is meant for Android Q. For older versions of Android you will need to create the path + file as usual. – Possible

Oh, this was tested on Android Pie not Q. So what I should do instead is check for the android version, and if it is Q do the code above and if it is lower use the usual deprecated code? – Entrammel

Yes, for older than Q you need to use your original code. Your code is deprecated only Q, but valid in older versions. – Possible

You have to use File.separator, not pathSeparator. I submitted an edit but the OP strangely didn't understand and rejected it. See #5972464 – Sigvard

    }
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
    Objects.requireNonNull(fos).close();
}

But how to check image is already saved or not! Nobody talking about it! – Binoculars

You can check exist file using this code if(isFilePresent()){ // call save function here }else{ // Toast file exist // } private boolean isFilePresent() { File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), name + ".jpg");return file.exists(); } – Unhelm

@RachitVohera Your answer is correct, but your previous comment is not - getExternalStoragePublicDirectory is deprecated in Android 10. That is why you used if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) { in your answer. – Indoxyl

Hey and what about if I wanna open this image file with a gallery using an intent. I passed the content URI but still I got file not found – Delfinadelfine

run media scan for add new media – Unhelm

@RachitVohera can you provide for storing video , i tried but my app getting crashed. – Husk

@Indoxyl Do you have any suggestions on "How to check the image exists or not"? Android Q – Foreignism

@AmanVerma You can try and open a InputStream, if it throws a FileNotFoundException, then the image is not available. – Indoxyl

@RachitVohera i tried to use your suggestion(i wan't to specify file extension) DISPLAY_NAME, name + ".jpg", but because we use MIME_TYPE, "image/jpg" it was saving file with name - name.jpg.jpg, because MIME_TYPE, "image/jpg" will automatically takes file extension according to specified mime_type.. – Cromwell

@VivekThummar what name ur passing as parameter? – Unhelm

it can be anything like img_timeStamp..basically it was file name/title – Cromwell

I have successfully saved a file using mediastore. Now I want to show user a button which will open it in gallery or photos app. But right now I have the path as Pictures/FolderName/filename.jpg But i want the full path like storage/emulated/0/Pictures/FolderName. How to get that or should i hardcode is like "storage/emulated/0" then the path to my file? – Foreignism

Answer 3

This is what i always use. You can try it.

 private void saveImageToStorage() throws IOException {

    OutputStream imageOutStream;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {

        ContentValues values = new ContentValues();
        values.put(MediaStore.Images.Media.DISPLAY_NAME, "image_screenshot.jpg");
        values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
        values.put(MediaStore.Images.Media.RELATIVE_PATH, Environment.DIRECTORY_PICTURES);
        Uri uri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

        imageOutStream = getContentResolver().openOutputStream(uri);
    } else {
        String imagePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
        File image = new File(imagePath, "image_screenshotjpg");
        imageOutStream = new FileOutputStream(image);
    }

    try {
        bitmapObject.compress(Bitmap.CompressFormat.JPEG, 100, imageOutStream);
    } finally {
        imageOutStream.close();
    }

}

I tried to use this approach, however, I get IllegalArgumentException: Failed to find configured root that contains /Pictures/2020-12-17_170659_photo.jpg when I attempt FileProvider.getUriForFile() immediately after saving the file on Android Q. In the manifest, the FileProvider provider is correctly set up. When using the MediaStore is it not possible to get the Uri after saving it (insert into table) ? – Mote

Maybe it is necessary to save my image with getExternalFilesDir() and then call FileProvider.getUriForFile()? – Mote

Answer 4

If anyone is looking how to save a photo into the DCIM folder, in a way that will appear in Google Photos later: (based on: https://github.com/yasirkula/UnityNativeGallery/blob/670d9e2b8328f7796dd95d29dd80fadd8935b804/JAR%20Source/NativeGallery.java#L73-L96)

ContentValue values = new ContentValues();
values.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_DCIM);
values.put(MediaStore.MediaColumns.DATE_TAKEN, System.currentTimeMillis());
values.put(MediaStore.MediaColumns.IS_PENDING, true);

Uri uri = context.getContentResolver().insert(externalContentUri, values);

if (uri != null) {
    try {
        if (WriteFileToStream(originalFile, context.getContentResolver().openOutputStream(uri))) {
            values.put(MediaStore.MediaColumns.IS_PENDING, false);
            context.getContentResolver().update(uri, values, null, null);
        }
    } catch (Exception e) {
        context.getContentResolver().delete( uri, null, null );
    }
}

Where WriteFileToStream is a standard method copying from file to stream.

This is excellent. Even today I still struggled to save to the correct location. Very good function in that lib. – Asphyxiant

Answer 5

Here is my version for 2022, this version was tested in Emulator SDK 27 and 30 also on Samsung S22 Phone.

TL:DR

For SDK < 29 you need following the code here, and need little add code after successfully take picture. You can see at my savePictureQ(...) function below

Otherwise, if you are SDK >= 29 just pass the URI at MediaStore.EXTRA_OUTPUT extras from contentResolver.insert(...) function

Since startActivityForResult(Intent) already deprecated my version using registerForActivityResult(...)

private val cameraLauncher =
    registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {
        if (it.resultCode == Activity.RESULT_OK) {
            val name: String = viewModel.savePictureQ()
            if (name != "") requireActivity().applicationContext.deleteFile(name)
            val cr = requireContext().contentResolver
            val uri = viewModel.getTargetUri()
            if (uri != null) {
                val bitmap = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                    val source = ImageDecoder.createSource(cr, uri)
                    ImageDecoder.decodeBitmap(source)
                } else MediaStore.Images.Media.getBitmap(cr, uri)
                val resized = Bitmap.createScaledBitmap(bitmap, 512, 512, true)
            }
        }
    }

I call the Intent in another file named Repository.kt, I also using fake viewModel to call Repository code. Here is how I call my viewModel code

    inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?
): View {
    viewModel = MenuViewModel(Injection.provideRepository(requireContext()))
    ...

        Manifest.permission.CAMERA
    )
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.Q) {
        if (ActivityCompat.checkSelfPermission(
                requireContext(),
                permissions[0]

        ) else MainActivity.accepted = true

    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {

For SDK < 29 I follow this code from Google Developer

this is how my manifest look after following the code:

<application ...>
    <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="com.your.package.name"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/camera_paths" />
    </provider>
</application>

make new res folder called xml, then make new xml file make sure the name same like you place on <meta-data> in <provider> and inside that file:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-files-path
        name="camera_take"
        path="Pictures" />
</paths>
