How to save an image in Android Q using MediaStore?

private void saveImage(Bitmap bitmap, @NonNull String name) throws IOException {
    OutputStream fos;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        ContentResolver resolver = getContentResolver();
        ContentValues contentValues = new ContentValues();
        contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, name + ".jpg");
        contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/jpg");
        contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES);
        Uri imageUri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
        fos = resolver.openOutputStream(Objects.requireNonNull(imageUri));
    } else {
        String imagesDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
        File image = new File(imagesDir, name + ".jpg");
        fos = new FileOutputStream(image);
    }
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
    Objects.requireNonNull(fos).close();
}

Image will store in Pictures Folder @ root level

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
    }
}
