@Override
public void onCallStateChanged(int state, String incomingNumber) {
    try {
        switch (state) {
        case TelephonyManager.CALL_STATE_RINGING: {
            //PAUSE
            if(BackgroundAudioService.mediaPlayer!=null){
                BackgroundAudioService.mediaPlayer.pause();}
            Log.i("pause","pause");
        break;
        }
        case TelephonyManager.CALL_STATE_OFFHOOK: {
        break;
        }
        case TelephonyManager.CALL_STATE_IDLE: {

            if(BackgroundAudioService.mediaPlayer!=null){
                BackgroundAudioService.mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);                   
                BackgroundAudioService.mediaPlayer.start();
