i creating media player. when press button (play) shows error.

08-20 11:35:21.473: d/mediaplayer(775): couldn't open file on client side, trying    server side  08-20 11:35:21.493: e/mediaplayer(775): error (1, -2147483648)  08-20 11:35:21.503: w/system.err(775): java.io.ioexception: prepare failed.: status=0x1

my code 

btnplay.setonclicklistener(new view.onclicklistener() {          @override         public void onclick(view v) {              uri audio = uri.parse("android.resourse://vishesh.mediaplayer/res/drawable/jannat");             try {                  mp.setdatasource(play.this,audio);                 mp.prepare();                 mp.start();             } catch (illegalargumentexception e) {                 e.printstacktrace();             } catch (securityexception e) {                 e.printstacktrace();             } catch (illegalstateexception e) {                 e.printstacktrace();             } catch (ioexception e) {                 e.printstacktrace();             }              btnplay.settext("pause");          }     });

better place or put such .mp3 or other files in assets folder.

these files once stored become part of android app , can read easily.

play sound asset.

assetfiledescriptor afd = getassets().openfd("audiofile.mp3");  player = new mediaplayer();  player.setdatasource(afd.getfiledescriptor(),afd.getstartoffset(),afd.getlength());  player.prepare();  player.start();
