How to get an array of bytes from a resource that can be used?

Question

I would like to get an array of bytes from a jpeg image located in my res / drawable file?

Does anyone know how to do this?

Answer 1

Get a decodeResource(android.content.res.Resources, int) Then either compress it to ByteArrayOutputStream () or copyPixelsToBuffer and get your array from the buffer. http://developer.android.com/reference/android/graphics/Bitmap.html

Answer 2

  Drawable drawable; Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap(); ByteArrayOutputStream stream = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream); byte[] bitmapdata = stream.toByteArray(); 

Answer 3

 ByteArrayOutputStream stream = new ByteArrayOutputStream(); mPhoto.compress(Bitmap.CompressFormat.JPEG /* FileType */, 100 /* Ratio */, stream); 

Hth!
