Question

I have a problem in Android screen capture. The captured image is transparent while the original image is solid JPEG file which is not transparent!
I tested in on many devices with different OS version and problem persists on all phones.
Here is my code for screen capture and also the final output

Code:

final Bitmap rawBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(rawBitmap);
rendererView.layout(0, 0, width, height);
rendererView.draw(canvas);
rawBitmap.compress(CompressFormat.PNG, 100, new FileOutputStream("/sdcard/test" + System.currentTimeMillis() + ".png"));

Result:

Answer 1

The problem was solved. When loading image source to ImageView, I used wrong setting for BitmapFactory Options.

The Code ( Before And After ):

    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inDither = false;
    options.inPurgeable = true;
    options.inInputShareable = true;
    //options.inPreferredConfig = Config.ARGB_4444; //WRONG
    options.inPreferredConfig = Config.ARGB_8888; //CORRECT
    bitmap = BitmapFactory.decodeFile(result.filePath(), options);

Thanks you all.
