audio - Android playing Music in Background -
i have activity code below:
public class player extends activity implements oncompletionlistener, onpreparedlistener, onerrorlistener, onbufferingupdatelistener, musicfocusable { private boolean playstate = false; private string station = "http://38.101.19.5:9157"; public static final float duck_volume = 0.1f; private string artistname = null; private string trackname = null; private textview artist; private textview track; private textview status; private button play; enum audiofocus { nofocusnoduck, // don't have audio focus, , can't duck nofocuscanduck, // don't have focus, can play @ low volume // ("ducking") focused // have full audio focus } private audiofocus maudiofocus = audiofocus.nofocusnoduck;

could 1 help?
if need play music in app, play in thread launched app/use asynctask class you.
use code. add class (enclosed in activity class).
public class backgroundsound extends asynctask<void, void, void> { @override protected void doinbackground(void... params) { mediaplayer player = mediaplayer.create(youractivity.this, r.raw.test_cbr); player.setlooping(true); // set looping player.setvolume(100,100); player.start(); return null; } } on other hand, if want use service can @ this page.
