I spend about 20 hours until now and my problem there still is .
I am creating an android application that has several Activities (mainMenu , aboutUs,setting).
I followed the best answered of below link and that was O.K .
Music played using asyncTask isn't stopping by using cancel
When i run my app,(my code is in mainActivity ), the music begin and it does not stop when navigate to other Activities . This is GOOD .
But i put a ToggleButton in my setting_activity Activity that i hope this Button starts and stops this music. NOW my question is how can i stop and/or start music again from setting_activity ?
in another solution :
I create a class MusicManager and i call it`s start and stop .
But this was several problems too :
Music started in mainMenu_activity but only play for about 15 seconds and then stopped.
I could not stop the music from another activities.At this time i play music in mainMenua_ctivity as this line codes :
MusicManager mm = new MusicManager(this, R.raw.background_sound);
mm.play();
How can i stop playing that ?
3. The music stopped when i navigate to other activities .
public class MusicManager implements OnPreparedListener {
static MediaPlayer mPlayer;
Context context;
private int mySoundId;
public MusicManager(Context ctx, int musicID) {
context = ctx;
mySoundId = musicID;
mPlayer = MediaPlayer.create(context, mySoundId);
mPlayer.setOnPreparedListener(this);
}
public void play() {
mPlayer = MediaPlayer.create(context, mySoundId);
}
public void stop() {
mPlayer.stop();
mPlayer.release();
}
#Override
public void onPrepared(MediaPlayer player) {
player.start();
mPlayer.setLooping(true);
mPlayer.setVolume(25, 25);
}
}
Finally i want to play a background music in all activities without stop/start music .
How can i do it ?
You could put the music player in a service. This would make it independent from the Activities and you would still be able to control the playback through intents.
Here are some code example about it: https://stackoverflow.com/a/8209975/2804473
The code below is written by Synxmax here at StackOverflow, and covered in the link above:
public class BackgroundSoundService extends Service {
private static final String TAG = null;
MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.idil);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return 1;
}
public void onStart(Intent intent, int startId) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
public void onStop() {
}
public void onPause() {
}
#Override
public void onDestroy() {
player.stop();
player.release();
}
#Override
public void onLowMemory() {
}
}
#Override
public void onCreate (){
super.onCreate();
Player = MediaPlayer.create(this, R.raw.jingle);
mPlayer.setOnErrorListener(this);
if(mPlayer!= null)
{
mPlayer.setLooping(true);
mPlayer.setVolume(100,100);
}
mPlayer.setOnErrorListener(new OnErrorListener() {
public boolean onError(MediaPlayer mp, int what, int
extra){
onError(mPlayer, what, extra);
return true;
}
});
}
public class serv extends Service{
MediaPlayer mp;
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
public void onCreate()
{
mp = MediaPlayer.create(this, R.raw.b);
mp.setLooping(false);
}
public void onDestroy()
{
mp.stop();
}
public void onStart(Intent intent,int startid){
Log.d(tag, "On start");
mp.start();
}
}
The top answer is correct, however you have to add the service to the manifest file.
<service android:enabled="true" android:name="BackgroundSoundService" />
Simon's answer above is correct. I had similar problem where I have fragments which had music player and I needed to go back to that UI on click of a button. Your case is similar but instead of going back to UI, you want to control playback. Here is what I did for my application. This takes care of playback of audio list including shuffle and repeat functionality. This takes care of showing media controls in notification bar too.
Create a service MusicPlayerService with following code:
public class MediaPlayerService extends Service implements MediaPlayer.OnCompletionListener,
MediaPlayer.OnPreparedListener, MediaPlayer.OnErrorListener, MediaPlayer.OnSeekCompleteListener,
MediaPlayer.OnInfoListener, MediaPlayer.OnBufferingUpdateListener,
AudioManager.OnAudioFocusChangeListener {
public static final String ACTION_PLAY = "pkg_name.ACTION_PLAY";
public static final String ACTION_PAUSE = "pkg_name.ACTION_PAUSE";
public static final String ACTION_PREVIOUS = "pkg_name.ACTION_PREVIOUS";
public static final String ACTION_NEXT = "pkg_name.ACTION_NEXT";
public static final String ACTION_STOP = "pkg_name.ACTION_STOP";

private MediaSessionManager mediaSessionManager;
private MediaSessionCompat mediaSession;
private MediaControllerCompat.TransportControls transportControls;
//AudioPlayer notification ID

//Used to pause/resume MediaPlayer
private int resumePosition;
// Binder given to clients
private final IBinder iBinder = new LocalBinder();
//List of available Audio files
private ArrayList<PlayableTrack> audioList;

Add the service to your manifest
<service android:name=".service.MediaPlayerService" />
Bind the service in MainActivity and declare methods to call the service
public class MainActivity {
private MediaPlayerService player;
boolean serviceBound = false;
public static final String Broadcast_PLAY_NEW_AUDIO = "pkg_name.PlayNewAudio";
//Binding this Client to the AudioPlayer Service
private ServiceConnection serviceConnection = new ServiceConnection() {
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
// We've bound to LocalService, cast the IBinder and get LocalService instance
MediaPlayerService.LocalBinder binder = (MediaPlayerService.LocalBinder) service;
player = binder.getService();
serviceBound = true;
}
#Override
public void onServiceDisconnected(ComponentName name) {
serviceBound = false;
}
};
// Call this method to play track
public void playAudio(int audioIndex, ArrayList<PlayableTrack> updatedList) {
//Check is service is active
audioList = updatedList;
if (!serviceBound) {
Intent playerIntent = new Intent(this, MediaPlayerService.class);
startService(playerIntent);
bindService(playerIntent, serviceConnection, Context.BIND_AUTO_CREATE);
} else {
//Service is active
//Send a broadcast to the service -> PLAY_NEW_AUDIO
Intent broadcastIntent = new Intent(Broadcast_PLAY_NEW_AUDIO);
sendBroadcast(broadcastIntent);
}
}
// Additional methods for control
public void start() {
player.playMedia();
}
public void pause() {
player.pauseMedia();
}
public boolean isPlaying() {
if (player != null && serviceBound) {
return player.isPlaying();
}
return false;
}
}
This is my solution:
1- first add a music file in raw folder (in my case coffee.mp3)
2- create a class named BackgroundSoundService that extends Service:
public class BackgroundSoundService extends Service {
MediaPlayer mediaPlayer;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
mediaPlayer = MediaPlayer.create(this, R.raw.coffee);
mediaPlayer.setLooping(true); // Set looping
mediaPlayer.setVolume(100, 100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals("PLAY")) {
if(mediaPlayer.isPlaying() == false) {
mediaPlayer.start();
Toast.makeText(getApplicationContext(), "Music Is Playing", Toast.LENGTH_SHORT).show();
}
}
if (intent.getAction().equals("STOP")) {
this.stopService(intent);
Toast.makeText(getApplicationContext(), "Music Stopped", Toast.LENGTH_SHORT).show();
}
return startId;
}
#Override
public void onDestroy() {
mediaPlayer.stop();
mediaPlayer.release();
}
#Override
public void onLowMemory() {
}
}
do not forget to define this service in application tag of android manifest.xml:
<service android:name=".BackgroundSoundService" />
3- for play button in your activity use this code:
btnPlay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String action = "PLAY";
Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
myService.setAction(action);
startService(myService);
}
});
3- for stop button in your activity use this code:
btnStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String action = "STOP";
Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
myService.setAction(action);
startService(myService);
}
});
I have created a simple android app with two activity which play music in background service, the app will pause the music if app is not visible to the user (for example user pressed home button).
you can see it in my github for more details.

So I'm attempting to have an audio stream play via the MediaPlayer Class. I was able to play the stream when only it in a Activity. Now I'm trying to have it work via a Service. I added comments to each functions so that I can track what its doing, everything seems to work fine, services get binded and all but now the onPrepared doesn't seems to initiate. I get no error until I try to stop the stream and says was stopped in State 4. I've tried reaching all possible cause and can't seem to find problem. I even build the unprepared within a new MediaPlayer class and still onPrepared doesn't get called. I've only put the service code below since all the other components work.
Any help would be great, Thank you.

I'm trying to make an audio player app, all running smoothly by utilizing activity and services. But there is a constraint when you have selected an audio and play it. Currently when the audio is playing, while selecting the same audio, I make it start from the beginning.
The question:
How to detect that the selected audio is being played. If the selected audio is different from what is being played it will be played from scratch but if it is the same it will not do anything.
In my activity :
//connect to the service
private ServiceConnection serviceConnection = new ServiceConnection(){
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
Services.MediaBinder binder = (Services.MediaBinder) service;
//get service
services = binder.getService();
mediaBound = true;
}
#Override
public void onServiceDisconnected(ComponentName name) {
mediaBound = false;
}
};
#Override
protected void onStart() {
super.onStart();
if(playIntent==null){
playIntent = new Intent(this, Services.class);
playIntent.putExtra("url", String.valueOf(urlRaw));
bindService(playIntent, serviceConnection, Context.BIND_AUTO_CREATE);
startService(playIntent);
}
}
In services :
Get variable using onBind:
#Override
public IBinder onBind(Intent intent) {
urlMedia = intent.getStringExtra("url");
return mediaBinder; // private final IBinder mediaBinder
}
I use in onStartCommand to play the selected audio.
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
try {
//An audio file is passed to the service through putExtra();
if(isPng()){
mPlayer.release();
}
mPlayer = MediaPlayer.create(getApplicationContext(), getResources().getIdentifier(String.valueOf(urlMedia),"raw",getPackageName()));
mPlayer.start();
} catch (NullPointerException e) {
stopSelf();
}
if (mPlayer != null)
initMusicPlayer();
return START_STICKY;
}
You are using bound service so you can create a method in service like
private String currentUrl;
public void playAudio(Sting url){
if(currentUrl.equals(url)) return;
this.currentUrl = url;
//Do other stuff.
}
And when service connected you can use this public method.
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
Services.MediaBinder binder = (Services.MediaBinder) service;
//get service
services = binder.getService();
services.playAudio("url");
mediaBound = true;
}
Use an another variable to keep the newly passed url in the onBind() method. Then check whether the new url is different from the old one.
// On Bind
#Override
public IBinder onBind(Intent intent) {
newUrlMedia = intent.getStringExtra("url");
return mediaBinder;
}
// On Start Command
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
try {
if (newUrlMedia.equals(urlMedia)) {
// Same url is passes
return START_STICKY;
} else {
// Different url
urlMedia = newUrlMedia;
if(isPng()){
mPlayer.release();
}
mPlayer = MediaPlayer.create(getApplicationContext(), getResources().getIdentifier(String.valueOf(urlMedia),"raw",getPackageName()));
mPlayer.start();
}
} catch (NullPointerException e) {
stopSelf();
}
if (mPlayer != null)
initMusicPlayer();
return START_STICKY;
}
I know similar kind of question has been asked before, but none of them are helping me. I am building a music player in which I want to connect my Music through my music player like play, pause etc. Currently, media player service is connected with playlist activity but I have custom designed my media player and I am not able to connect it to the service class.
my MusicPlayer Activity is like this:
public class MusicPlayer extends AppCompatActivity implements PlaylistFragment.OnFragmentInteractionListener{
public static final String Broadcast_PLAY_NEW_AUDIO = "com.example.anuj.musicmetest.PlayNewAudio";
ImageView buttonPlayToggle;
MediaPlayer mediaPlayer;
MediaPlayerService player;
boolean serviceBound = false;
private ServiceConnection serviceConnection = new ServiceConnection() {
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
MediaPlayerService.LocalBinder binder = (MediaPlayerService.LocalBinder) service;
player = binder.getService();
serviceBound = true;
}
#Override
public void onServiceDisconnected(ComponentName name) {
serviceBound = false;
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_player);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setTitle("Music Player");
buttonPlayToggle = (ImageView) findViewById(R.id.button_play_toggle);
buttonPlayToggle.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mediaPlayer == null) return;
if (mediaPlayer.isPlaying()) {
updatePlayToggle(true);
mediaPlayer.pause();
} else {
updatePlayToggle(false);
mediaPlayer.start();
}
}
});
if (!serviceBound) {
Intent playerIntent = new Intent(this, MediaPlayerService.class);
startService(playerIntent);
bindService(playerIntent, serviceConnection, Context.BIND_AUTO_CREATE);
} else {
Intent broadcastIntent = new Intent(Broadcast_PLAY_NEW_AUDIO);
sendBroadcast(broadcastIntent);
}
}
public void updatePlayToggle(boolean play) {
buttonPlayToggle.setImageResource(play ? R.drawable.ic_pause : R.drawable.ic_play);
}
My ServicecClass is like this:

I have a service playing music, and I need it do display a notification with "play", "pause" and "stop" buttons. My service code is:
public class RadioService extends Service implements MediaPlayer.OnPreparedListener {
MediaPlayer radioPlayer;
String url = "radiourl";
String action;
public RadioService() {
}
#Override
public IBinder onBind(Intent intent) {
Log.e("Service", "Bind");
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.e("Service", "onStart");
action = intent.getAction();
Log.e("ServiceAction", action);
switch (action) {
case "play":
radioPlayer = new MediaPlayer();
radioPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
radioPlayer.setDataSource(url);
} catch (IOException e) {
Log.e("setDataSource", e.toString());
}
radioPlayer.prepareAsync();
radioPlayer.setOnPreparedListener(this);
}
return START_STICKY;
}
#Override
public void onPrepared(MediaPlayer radioPlayer) {
Log.e("Service", "onPrepared");
radioPlayer.start();
}
#Override
public void onDestroy() {
Log.e("Service", "onDestroy");
if(radioPlayer != null && radioPlayer.isPlaying()) {
radioPlayer.stop();
radioPlayer.reset();
radioPlayer.release();
}
super.onDestroy();
}
}
My notification has to be compatible with API 16 and higher. I want notification buttons to send an action to my service, that will execute a proper case in my switch instruction. Is this even possibe? How should my service look like?
I am working on Integrating a Quickblox based video chat into my app.
Here i am running a listener in foreground service which listens to the video call initiated by opponent. here in switch statement, at call accept state i am calling a new activity which is nothing but a dialler screen with accept and disconnect button. accept button connects the call but disconnect cuts the call and closes the activity, but again the same activity (dialler screen) opens repeatedly after multiple times, My question is how to make service to call once and ignore the rest calls if its disconnected. (Am sending reject signal to opponent thus call drops from opponent but here service calls activity repeatedly though call is dropped from opponent)
Here is the code
VchatListener service with OnQBVideoChatListener with switch statement has a accept call state which calls new activity
public class VChatListener extends Service {
private VideoChatConfig videoChatConfig;
private CallState state;
QBUser a=DataHolder.getInstance().getCurrentQbUser();

startForeground(notif_id, getMyActivityNotification(""));
}

// TODO Auto-generated method stub
//startForeground(FOREGROUND_ID, notification);
