java.lang.OutOfMemoryError in .whenDone()

Not always, but from time to time, I get:

 E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.example.debug, PID: 26609

comapred to other similar reports, it is often casused during the Bitmap creation process. I am cropping a part out of the original image and rotating this. SO the new image should be smaller than the original image,

fotoapparat.takePicture()
    .toBitmap()
    .whenDone(new WhenDoneListener<BitmapPhoto>() {
        @Override
        public void whenDone(@Nullable BitmapPhoto photo) {
            if (photo != null){
                int widthBitmap = photo.bitmap.getWidth();
                int heightBitmap = photo.bitmap.getHeight();
                int resizedWidth = heightBitmap / 4 * 3;
                int offsetX = (widthBitmap - resizedWidth) / 2;

                Matrix matrix = new Matrix();
                matrix.postRotate(90);

                Bitmap resizedBitmap = Bitmap.createBitmap(photo.bitmap, offsetX, 0, resizedWidth, heightBitmap, matrix, true);
                bitmapPhoto = new BitmapPhoto(resizedBitmap, 0);
            }
        }
    });

Calling createBitmap is a memory intensive operation. Consider rotating the image by using view transformation methods instead.
