image:

the error occurred because android studio expected resource file of type raw.

solution 1:

create new folder in "res" folder called "raw", , put icon there. raw folder should contain media files of app.

then replace

inputstream = getresources().openrawresource(r.drawable.icon); 

with

inputstream = getresources().openrawresource(r.raw.icon); 

---

solution 2:

another solution this. doesn't require create raw folder:

inputstream = getresources().openrawresource(+ r.drawable.icon);
