推荐答案

感谢您的答案。这就是我终于解决了它：

Thank you for your answers. This is how I finally resolved it:

 Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(), 
            R.drawable.ic_launcher);


     Bitmap bitmap = bitmapOrg;
     ByteArrayOutputStream stream = new ByteArrayOutputStream();   
     bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);   
     byte[] imageInByte = stream.toByteArray(); 
     long lengthbmp = imageInByte.length; 

鸭preciate您的时间和答案：）
