Playing BG Music Across Activities in Android

Hello! First time to ask a question here at stackoverflow. Exciting! Haha.

We're developing an Android game and we play some background music for our intro (we have an Intro Activity) but we want it to continue playing to the next Activity, and perhaps be able to stop or play the music again from anywhere within the application.

What we're doing at the moment is play the bgm using MediaPlayer at our Intro Activity. However, we stop the music as soon as the user leaves that Activity. Do we have to use something like Services for this? Or is MediaPlayer/SoundPool enough? If anyone knows the answer, we'd gladly appreciate your sharing it with us. Thanks!

Answer 1

You can also create a service which play music using mediaplayer as below.

Intent svc=new Intent(this, BackgroundSoundService.class);
startService(svc); //OR stopService(svc); 

public class BackgroundSoundService extends Service {
    private static final String TAG = null;
    MediaPlayer player;
    public IBinder onBind(Intent arg0) {

        return null;
    public void onCreate() {

        player = MediaPlayer.create(this, R.raw.idil);
        player.setLooping(true); // Set looping

    public int onStartCommand(Intent intent, int flags, int startId) {


        return 1;

    public void onStart(Intent intent, int startId) {
        // TODO

    public IBinder onUnBind(Intent arg0) {
        // TODO Auto-generated method stub

        return null;

    public void onStop() {

    public void onPause() {

    public void onDestroy() {


    public void onLowMemory() {

Answer 2

Create a static SoundManager using either SoundPools or MediaPlayers.

Create a static flag called keepMusicGoing.

Start the music when the first activty is created.

When switching actvities set keepMusicGoing to true.

On the onStop event of your activities check if keepMusicGoing is true,if so leave the music on, then set keepMusicGoing to false.

If they press the home button the keepMusicGoing flag will be false so the music will stop when the activity loses focus.

Email me and I can send you a couple SoundManagers that I wrote one uses MediaPlayers and the other SoundPools

Answer 3

If I understand your situation correctly, then I have confronted the same problem a few times. I am using a different thread to play music in my applications. This implementation passes a static reference to a Context that I know will be alive for the time that the music will be playing.

public class AudioPlayer extends Thread {
private Context c;
private Thread blinker;
private File file;

public AudioPlayer (Context c, File file) {
    this.c = c;
    this.file = file;

public void go () {
    blinker = this;
    if(!blinker.isAlive()) {

public void end () {
    Thread waiter = blinker;
    blinker = null;
    if (waiter != null)
        waiter.interrupt ();

public void run () {
    MediaPlayer ap = MediaPlayer.create(c, Uri.fromFile(file));
    int duration = ap.getDuration();
    long startTime = System.currentTimeMillis();
    try {
        Thread thisThread = Thread.currentThread();
        while (this.blinker == thisThread && System.currentTimeMillis() - startTime < duration) {           
            Thread.sleep (500);  // interval between checks (in ms)
        ap.stop ();
        ap.release ();
        ap = null;
    } catch (InterruptedException e) {
        ap.stop ();
        ap = null;

Answer 4

First i used the method where to keep a "keepMusicPlaying" flag provided by Chad. I think its more elegant to just use the onStart and onStop methods of your activitys.

Create an own class "SoundManager" and call some onStart and onStop classes in it from all your activitys onStart and onStop (or use a base activity class). Keep track of the onStart and onStop with a startCounter(startCounter++ in onstart and startCounter-- in onstop). Because the start of a new activity is called before the onStop of the old activity you always know if the onStart is called for the first Time (startCounter == 1) or started from another of your activitys (startCounter == 2). Same with the onStope(startCounter == 0 means the App was closed, startCounter == 1 means its just the stop from an old activity but there is a new).

This way you encapsulate everything into your SoundManager instead of having to call some keepMusicPlaying method/flag on every activity start inside your app.

    public void OnStart()
        if (startCounter == 1)
            //start music here

    public void OnStop()
        if (startCounter == 0)
            // stop music here

Answer 5

You can try using the AsyncPlayer but you should keep a reference to the class in order to stop the sound from playing.

You can create a Uri to a local resource using Uri uri = Uri.parse("android.resource:// beep.mp3");.

Hope this helps.

Answer 6

By combining Chad's and Kedu's answers and adding my own flavor, I created this working solution:

// Parent Activity which every Activity extends
public class ParentActivity extends AppCompatActivity {

    protected void onCreate(Bundle savedInstanceState) {

    protected void onStart() {

    protected void onStop() {
// Controller class for handling background music
public abstract class Music {

    private static MediaPlayer mediaPlayer;
    private static int startCounter = 0;

    public static void onStart() {
        if (startCounter == 1) {
            mediaPlayer = MediaPlayer.create(InitializeActivity.getContext(), R.raw.background_music);
            mediaPlayer.setVolume(1f, 1f);

    public static void onStop() {
        if (startCounter == 0) {

And that's it, super simple!
