open image from drawable using android gallery app

Question

My app has 12 pictures saved in drawable, and i made on a list of 12 item, so if any item pressed it should open the corresponding image. I want to open these images by default gallery application. i tried this

Intent intent = new Intent();
                    intent.setAction(android.content.Intent.ACTION_VIEW);
                    intent.setDataAndType(Uri.parse("android.resource://com.app.mid/" + R.drawable.pic10), "image/png");
                    startActivity(intent); 

But it gives me error :ActivityNotFoundException, No activity found to handle intent.

What should i do ? Thanks in advance :)

startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("content://media/external/images/media")));
