Intent intent = new Intent(this, ActivityB.class);
ByteArrayOutputStream baos=new ByteArrayOutputStream();

byte [] bitmapByte =baos.toByteArray();
intent.putExtra("imgbitmap", bitmapByte);

startActivity(intent);

byte [] bis=in.getByteArrayExtra("imgbitmap");
 bitmap= BitmapFactory.decodeByteArray(bis, 0, bis.length);
