I am not able to know that what directory is missing here the program is compiling properly and not giving any error but it is giving runtime error.What changes it need The error in setting the Inputstream command or

InputStream is =context.getResources().openRawResource(+ R.drawable.wale);
  bmp= BitmapFactory.decodeStream(is);

this is the main error.

Answer 1

remove context from InputStream is =context.getResources().openRawResource(+ R.drawable.wale); bmp= BitmapFactory.decodeStream(is);
