BitmapFactory: Unable to decode stream: java.io.FileNotFoundException:open failed: EACCES (Permission denied) on Android Q

Adding android:requestLegacyExternalStorage="true" to the manifest's application block could actually solve the issue!

On Android 10, they introduced the concept of "Scoped Storage" and this way, you no longer can OPEN a image using its path. You can get more info HERE.

So now you have to decode it using its ParcelFileDescriptor and its Uri.

You can:

final Cursor cursor = this.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                        projection, null, null, MediaStore.Images.ImageColumns.DATE_TAKEN + " DESC");
if (cursor.moveToFirst()) {
    final ImageView imageView = (ImageView) findViewById(R.id.pictureView);


    if (Build.VERSION.SDK_INT >= 29) {
        // You can replace '0' by 'cursor.getColumnIndex(MediaStore.Images.ImageColumns._ID)'
        // Note that now, you read the column '_ID' and not the column 'DATA'
        Uri imageUri= ContentUris.withAppendedId(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, cursor.getInt(0));

        // now that you have the media URI, you can decode it to a bitmap
        try (ParcelFileDescriptor pfd = this.getContentResolver().openFileDescriptor(mediaUri, "r")) {
            if (pfd != null) {
                bitmap = BitmapFactory.decodeFileDescriptor(pfd.getFileDescriptor());
            }
        } catch (IOException ex) {

        }
    } else {
        // Repeat the code you already are using
    }
}
