Pause music player on a phone call and again resume it after phone call in android

Question

I am using android.media.MediaPlayer object to play audio files in my app. Everything works fine but when a phone call comes while a song is playing the app doe

Answer 1

Introduce a PhoneStateListener in your Application like so:

private PhoneStateListener mPhoneListener = new PhoneStateListener() {
    public void onCallStateChanged(int state, String incomingNumber) {
        try {
            switch (state) {
                case TelephonyManager.CALL_STATE_RINGING:
                    pauseStream();
                    break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                    break;
                case TelephonyManager.CALL_STATE_IDLE:
                    resumeStream();
                    break;
                default:
            }
        } catch (Exception e) {
            Log.e(TAG, e.getMessage());
        }
    }
};

Then you need to set it up in your onCreate() or in your onStartCommand() method in case of a Service:

        radioStream.setAudioStreamType(AudioManager.STREAM_MUSIC);
        radioStream.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer stream) {
                telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
                telephonyManager.listen(mPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);
                isMusicPlaying = true;
                isServiceRunning = true;
                stream.start();
            }
        });
        try {
            radioStream.prepare();
        } catch (IllegalStateException e1) {
            e1.printStackTrace();
            streamErrorHandler();
        } catch (IOException e1) {
            e1.printStackTrace();
            streamErrorHandler();
        }

and you can implement your version of the following methods:

public static void pauseStream() {
    if (isServiceRunning) {
        if (radioStream.isPlaying()) {
            isMusicPlaying = false;
            radioStream.pause();
        }
    } else {
        Log.i(TAG, "service isn't running");
    }
}

public static void resumeStream() {
    if (isServiceRunning) {
        if (!radioStream.isPlaying()) {
            isMusicPlaying = true;
            radioStream.start();
        }
    } else {
        Log.i(TAG, "service isn't running");
    }
}

radioStream is your static MediaPlayer object. I am using this within a service so you can drop out the isServiceRunning but this should work for anyone's case.
