rather using phonestatelistener, might instead use audiomanager.requestaudiofocus. allow tell android using particular audio stream, , you'll callbacks whenever application wants play audio (like when phone receives phone call). then, can choose either stop playing, or pause until other application finished. example:
audiomanager.requestaudiofocus(new audiomanager.onaudiofocuschangelistener() { @override public void onaudiofocuschange(int reason) { switch (reason) { case audiomanager.audiofocus_loss: // lost focus, pause playback break; case audiomanager.audiofocus_gain: // gained focus, start playback break } } });
