}

i want play next song if playing. music player starts playing second song open application.

don't know intended archive here can try call playsong(); instead of calling both.

void initmediaplayer(){ mp.setaudiostreamtype(audiomanager.stream_music); mp.setoncompletionlistener(new mediaplayer.oncompletionlistener() {     @override     public void oncompletion(mediaplayer mediaplayer) {         try {              playsong();          } catch (exception e) {             e.printstacktrace();         }     } }); }
