You can open it using openRawResource(). See more at the documentation.

See this post regarding how to construct a uri to raw resource, though as far as I know it is not recommended.

You can access it through its resource ID. See previous answers such as this one: Select Drawable file path

Here is the code segment showing how you can refer to an image through its resource ID.

Bitmap mBitmap = BitmapFactory.decodeResource(getResources(),
   R.drawable.pic1);
int pic_width  = mBitmap.width();
int pic_height = mBitmap.height();

See here for more detail
