Question

I want to take the image from drawable folder but it should be in the byte[] format.So that i can save that byte[] into the database.I have gone through links but that is taking image from drawable folder in String or Drawable format. Any suggestion for me plz..

Answer 1

Obtain the drawable using getResources() method.

Drawable drawable= getResources().getDrawable(R.drawable.image1);

Type cast to BitmapDrawable,

Bitmap bitmap = ((BitmapDrawable)drawable).getBitmap();

Write a compressed version of the bitmap to the specified outputstream via compress method.

ByteArrayOutputStream out = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
byte[] buffer= out.toByteArray();
