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 have a problem in my service, the service is runnig from MainActivity (i am doing test) and extends of service.
i want to use the service from foreground and background (when the app is closed) and i already have my first problem:
my service(have a counter that is displayed by LOG) is restarting when i close the app.
also i want to be able to use the service with the open app and close app, in other words to use both the Service Started and Link Service
public class MyService extends Service {
private Thread backgroundThread;
private boolean isRunning;
public MyService() {
Log.e("MyService","constructor");
}
#Override
public void onCreate() {
super.onCreate();
isRunning = false;
}
#Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
#Override
public int onStartCommand(final Intent intent, int flags, int startId) {
Log.e("onStartCommand","Servicio Llamado");
if (!this.isRunning) {
Log.e("onStartCommand","hilo iniciandose");
this.backgroundThread = new Thread(myTask);
runTask();
}
return super.onStartCommand(intent, flags, startId);
}
#Override
public void onDestroy() {
super.onDestroy();
Log.e("onDestroy","servicio destuido");
}
private void runTask(){
this.isRunning = true;
this.backgroundThread.start();
}
private Runnable myTask = new Runnable() {
public void run() {
Log.e("myTask","hilo iniciado");
int i = 0;
do{
pauseService();
Log.e("myTask","hilo contador: "+i);
//Toast.makeText(getApplicationContext(),"CONTADOR = "+j, Toast.LENGTH_SHORT).show(); //no working :(
i++;
}while (i<10);
/*
//linea de detencion del servicio
//stopSelf();
isRunning=false;
backgroundThread.interrupt();
//backgroundThread = new Thread(myTask);
*/
Log.e("myTask","hilo cerrado");
}
};
private void pauseService(){
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
In main Activity
Intent intent = new Intent(MainActivity.this,MyService.class);
intent.putExtra("iteraciones",10);
startService(intent);
why because the service restarts when I close the application and how can I avoid it?
If I enter a region of a beacon with my Android device I like to show a notification. Thats well documented at Android SDK Quickstart
This is just working as long as the app is active. How do I get notifications when the app is closed?
I build a service by myself:
BeaconRangingService.java
public class BeaconRangingService extends Service {
private static final String TAG = BeaconRangingService.class.getSimpleName();
private BeaconManager beaconManager;
#Override
public void onCreate() {
super.onCreate();
beaconManager = BeaconManager.newInstance(getApplicationContext());
beaconManager.setMonitorPeriod(MonitorPeriod.MINIMAL);
beaconManager.setForceScanConfiguration(ForceScanConfiguration.DEFAULT);
beaconManager.registerMonitoringListener(new BeaconManager.MonitoringListener() {
#Override
public void onMonitorStart() {
Log.v(TAG, "start monitoring beacons");
}
#Override
public void onMonitorStop() {
Log.wtf(TAG, "stop monitoring beacons");
}
#Override
public void onBeaconsUpdated(Region region, List<Beacon> list) {
}
#Override
public void onBeaconAppeared(Region region, Beacon beacon) {
Toast.makeText(getApplicationContext(), "Beacon appeared\n BEACON ID: " + beacon.getBeaconUniqueId(), Toast.LENGTH_SHORT).show();
}
#Override
public void onRegionEntered(Region region) {
}
#Override
public void onRegionAbandoned(Region region) {
}
});
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.v(TAG, "service started");
if (!beaconManager.isBluetoothEnabled()) {
Log.w(TAG, "bluetooth disabled, stop service");
stopSelf();
} else {
connect();
}
return super.onStartCommand(intent, flags, startId);
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy() {
Log.v(TAG, "service destroyed");
beaconManager.stopMonitoring();
beaconManager.disconnect();
beaconManager = null;
super.onDestroy();
}
private void connectBeaconManager() {
try {
beaconManager.connect(new OnServiceBoundListener() {
#Override
public void onServiceBound() {
try {
HashSet<Region> regions = new HashSet<>();
regions.add(Region.EVERYWHERE);
beaconManager.startMonitoring(regions);
} catch (RemoteException e) {
e.printStackTrace();
}
}
});
} catch (RemoteException e) {
throw new IllegalStateException(e);
}
}
}
AndroidManifest.xml
<service
android:name="com.your.package.BeaconRangingService"
android:exported="false"/>
start service
Intent intent = new Intent(this, BeaconRangingService.class);
startService(intent);
I know nothing regarding kontakt.io but there is a library and reference app for AltBeacon which provides this functionality. https://github.com/AltBeacon
I believe this is generic Android functionality, and not anything magic to their implementation.
#erdna have you tested the sample kontakt admin app? There is an approach in which Toasts appear when the application is in foreground and standard notifications appear when the app is working in background.
https://github.com/kontaktio/kontakt-beacon-admin-sample-app
#erdna I guess that it should be IntentService for long running services, that monitors incoming beacon events as intents in a onHandleIntent(Intent intent) method. #dawid-gdanski I'm not sure what class do you refer to.
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 MediaPlayer mediaPlayer;
//MediaSession
private MediaSessionManager mediaSessionManager;
private MediaSessionCompat mediaSession;
private MediaControllerCompat.TransportControls transportControls;
//AudioPlayer notification ID
private static final int NOTIFICATION_ID = 101;
//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;
private int audioIndex = -1;
//Handle incoming phone calls
private boolean ongoingCall = false;
private PhoneStateListener phoneStateListener;
private TelephonyManager telephonyManager;
private Bitmap albumArtBitmap;

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.
Sorry for my English.
I have one Activity that call one service and i want to stop this service from that Activity.
I try to use stopService(getApplicationContext(), TempService.class) And it doesn't worked.
Here is my service code
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d("Debug", "Service start");
mgr = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
temp = mgr.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE);
mgr.registerListener(this, temp, SensorManager.SENSOR_DELAY_FASTEST);
return START_STICKY;
}
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
public void onDestroy() {
Log.d("DEBUG", "on destroy");
notificationManager.cancel(0);
super.onDestroy();
}
And in my Activity : boolean t always return false value.
I have no idea.
private void processStopService(final String tag) {
Intent intent = new Intent(getApplicationContext(), TempService.class);
intent.addCategory(tag);
boolean t = stopService(intent);
if (t)
{
Log.e("DEBUG", "TRUE");
}
else
Log.e("DEBUG", "FALSE");
}
Do not use categories with services. Delete the addCategory() call on your Intent.
