How to handle Audio continously with Landscape and portrait in Android? -

i have created audio in 1 activity media player. have run start, pause, resume when rotate screen landscape or portrait mode song playing twice.

here code:

public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.audio);         init();          prefs = preferencemanager.getdefaultsharedpreferences(this);         final sharedpreferences.editor prefsedit = prefs.edit();          mp = mediaplayer.create(audio_activity.this, r.raw.subhanallah);         log.e("song playing", "in  mediya player ");          mp.setlooping(false);         mp.start();          system.out.println("media plyer start !!!");         prefsedit.putboolean("mediaplaying", true);         prefsedit.commit();         btnchapter.setenabled(false);          system.out.println("b4 button click!!!!");       }      @override     public void onconfigurationchanged(configuration newconfig) {         super.onconfigurationchanged(newconfig);          setrequestedorientation(activityinfo.screen_orientation_landscape);      }      @override     public void onpause() {         super.onpause();          sharedpreferences.editor prefsedit = prefs.edit();         boolean isplaying = prefs.getboolean("mediaplaying", false);         if (isplaying)         {             mp.pause();             int position = mp.getcurrentposition();             log.e("current ", "position -> " + position);             prefsedit.putint("mediaposition", position);             prefsedit.commit();         }     }      @override     protected void onresume() {          super.onresume();          mp.start();          boolean isplaying = prefs.getboolean("mediaplaying", false);         if (isplaying) {             int position = prefs.getint("mediaposition", 0);             mp.seekto(position);             // mp.start();          }     }       @override     public boolean onkeydown(int keycode, keyevent event) {         if ((keycode == keyevent.keycode_back)) {              if (mp != null) {                 if (mp.isplaying()) {                      mp.stop();                 }             }             finish();             return true;         }         return super.onkeydown(keycode, event);     }       } 

do not rely on sharedpreferences value in onpause(). use start player in oncreate().
