MediaBrowserServiceCompat stopped playing music when app goes background

Mediabrowsercompat not playing the music when app goes background. If I don't disconnect the mediabrowsercompat instance in activity onStop method then it is working. But that is not the solution as according to documentation we have to disconnect the service once app goes background.
This is my mediabroweserservicecomat class (I am using Exoplayer to play music):

After wasting 2 sleepless nights. I found a workaround. I don't know whether it's a correct way to handle this. But if you have ever faced this problem. You can try it:
#Override
protected void onStart() {
super.onStart();
if (!mediaBrowserCompat.isConnected())
mediaBrowserCompat.connect();
}
#Override
protected void onStop() {
super.onStop();
Log.i("onStop","onStop");
MediaControllerCompat mediaController = MediaControllerCompat.getMediaController(this);
if (mediaController != null) {
mediaController.unregisterCallback(controllerCallback);
}
// mediaBrowserCompat.disconnect();
}
#Override
protected void onDestroy() {
super.onDestroy();
mediaBrowserCompat.disconnect();
}

Trouble running background service Android

I have some simple code intended to start a background service that updates a static integer from my MainActivity every second. I also have a button that when clicked, updates a TextView with the value of that static integer. However, every time I start the service, it only increments the value once and stops, instead of continuously incrementing it until I press stop service.
This is my code:
public class MainActivity extends AppCompatActivity {
public static int count;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
count = 0;
}
public void pressButton(View view) {
TextView textView = (TextView) findViewById(R.id.textView);
textView.setText("" + count);
}
public void startService(View view) {
startService(new Intent(getBaseContext(), MyService.class));
}
public void stopService(View view) {
stopService(new Intent(getBaseContext(), MyService.class));
}
}
And my service:
public class MyService extends Service {
public MyService() {
}
#Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
MainActivity.count++;
}
}, 1000);
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
}
}
I can't figure out what seems to be the problem.

public class DownloadService extends IntentService {
String pdfName = "";
public DownloadService() {
super("DownloadService");
}
#Override
protected void onHandleIntent(#Nullable Intent intent) {
showNotificationProgress();
if (intent != null) {
pdfName = intent.getStringExtra("pdfName");
}
downloadPDF ( ) // Implement this method

}

} catch (IOException e) {

e.printStackTrace();
} finally {
if (completed) {
//do something
}
}
} else {
hideNotificationProgress();
}
}
private static byte[] decodeBase64String(String encodedString) {
return Base64.decode(encodedString, Base64.DEFAULT);
}
public static void hideNotificationProgress() {
mNotifyManager.cancel(1);
}
private void showNotificationProgress() {
final int id = 1;
mNotifyManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
final NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setContentTitle("PDF Download")
.setContentText("Download in progress")
.setSmallIcon(android.R.drawable.stat_sys_download);
// Start a lengthy operation in a background thread
new Thread(
new Runnable() {
#Override
public void run() {
// Do the "lengthy" operation 20 times
// Sets the progress indicator to a max value, the
// current completion percentage, and "determinate"
// state
mBuilder.setProgress(0, 0, true);
// Issues the notification
mNotifyManager.notify(id, mBuilder.build());
// Sleeps the thread, simulating an operation
// that takes time
try {
// Sleep for 5 seconds
Thread.sleep(1000);
} catch (InterruptedException ignored) {
}
}
}
// Starts the thread by calling the run() method in its Runnable
).start();
}
}
Why don't you try Intent Service like this.
And start this service as below
Intent intent = new Intent(AActivity, DownloadService.class);
intent.putExtra("pdfName", pdfName);
holdingActivity.startService(intent);

This code shows how to update the UI in an Android Activity from a background Service.

Post delay only runs one time. You need to schedule a reoccurring task or just create a Runnable that will recall the task over and over.
final Handler mHandler = new Handler();
Runnable runner = new Runnable() {
#Override
public void run() {
MainActivity.count++;
mHandler.postDelayed(runner, 1000);
}
}
mHandler.postDelayed(runner, 1000);

sinch conference call hung up right after it starts

I managed to start a conference call cut it closes right after I start it with HUNG_UP cause and I got this in my log:
11-03 17:28:08.940: E/sinch-android-rtc(19101): peermediaconnection: virtual void rebrtc::SetSDPObserver::OnFailure(const string&)Failed to set remote answer sdp: Offer and answer descriptions m-lines are not matching. Rejecting answer.
11-03 17:28:08.940: E/sinch-android-rtc(19101): mxp: Failed to set remote answer sdp: Offer and answer descriptions m-lines are not matching. Rejecting answer.
can anybody help me solve this please?
Edit:
my scenario is when a user clicks the call button I ask him if he wants to start a new call or join an already created one.
I managed to make my code from this question (Sinch conference call error) work as my GroupService class had some bugs.
I start my call like this:
Intent intent1 = new Intent(CreateGroupCallActivity.this,SinchClientService.class);
intent1.setAction(SinchClientService.ACTION_GROUP_CALL);
String id = String.valueOf(uid) + "-" + call_id.getText().toString();
intent1.putExtra(SinchClientService.INTENT_EXTRA_ID,id);
startService(intent1);
and in my SinchClientService:
if(intent.getAction().equals(ACTION_GROUP_CALL))
{
String id = intent.getStringExtra(INTENT_EXTRA_ID);
if(id != null)
groupCall(id);
}
public void groupCall(String id) {
if (mCallClient != null) {
Call call = mCallClient.callConference(id);
CurrentCall.currentCall = call;
Log.d("call", "entered");

Timer on onDraw

start button -> game.class -> gameview.class then loop again on game.class when player finish the 1st level it will call gameview.class to generate again the 2nd level. My problem is that my timer will also regenerate and restarts when going on the 2nd level. How can I make my timer pause and resume in this kind of flow of game?
on my Game.Class:
public void onCreate(Bundle savedInstanceState) {
timeCounter = new TimeCounter();
super.onCreate(savedInstanceState);
Intent intent = getIntent();
Bundle extras = intent.getExtras();
this.maze = (Maze) getLastNonConfigurationInstance();
if (this.maze == null) {
this.maze = (Maze) extras.get("maze");
}
gview = new GameView(this);
gview.setTimeCounter(timeCounter);
gview.setMaze(this.maze);
setContentView(gview);
and on my GameView.Class:
protected void onDraw(Canvas canvas) {
if (startTimer) {
timeCounter.start();
invalidate();
int secondss = timeCounter.getTimeSeconds();
String text = String.format("%02d:%02d", secondss / 60,
secondss % 60);
timer.getTextBounds(text, 0, text.length(), textBounds);
canvas.drawText(text, (this.getWidth() - textBounds.right) - 5,
(this.getHeight() - textBounds.bottom) - 5, timer);
}
and when the 1st level finish it will call this method:
void shownextmaze() {
Random rand = new Random();
Intent game = new Intent(context, Game.class);
nextmaze = rand.nextInt(6) + 1;
Maze maze = MazeCreator.getMaze(nextmaze);
game.putExtra("maze", maze);
context.startActivity(game);
timeCounter.resume();
}
How can I make my timer run until the 4 levels are cleared?

It is logical that onDraw will be called and timer will be start again. You should start your timer in a service and run it in background thread. Each time you want to access it value you can bind to service.
Check this guideline.
In this code each time you open the app you will see updated value:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService(new Intent(MainActivity.this, MyService.class));
doBindService();
((Button) findViewById(R.id.button1))
.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mBoundService != null) {
((TextView) findViewById(R.id.textView1))
.setText(mBoundService.getValue() + "");
}
}
});
((Button) findViewById(R.id.button2))
.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mBoundService = null;
stopService(new Intent(MainActivity.this,
MyService.class));
doUnbindService();
}
});
}
private MyService mBoundService;
private boolean mIsBound;
private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className, IBinder service) {
mBoundService = ((MyService.LocalBinder) service).getService();
((TextView) findViewById(R.id.textView1)).setText(mBoundService
.getValue() + "");
}
public void onServiceDisconnected(ComponentName className) {
mBoundService = null;
}
};
void doBindService() {
bindService(new Intent(MainActivity.this, MyService.class),
mConnection, Context.BIND_AUTO_CREATE);
mIsBound = true;
}
void doUnbindService() {
if (mIsBound) {
// Detach our existing connection.
unbindService(mConnection);
mIsBound = false;
}
}
#Override
protected void onDestroy() {
super.onDestroy();
doUnbindService();
}
}
And a service:
public class MyService extends Service {
private final IBinder mBinder = new LocalBinder();
// private TimeCounter timeCounter;
int x = 0;
public class LocalBinder extends Binder {
MyService getService() {
return MyService.this;
}
}
#Override
public void onCreate() {
new Thread(new Runnable() {
public void run() {
while (true) {
x++;
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
}
#Override
public IBinder onBind(Intent intent) {
return mBinder;
}
public int getValue() {
return x;
}
}
Maybe you need activity_main.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/textView1"
android:text="Show Updated value" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/button1"
android:layout_marginTop="28dp"
android:text="Stop Service" />
</RelativeLayout>

android - how can I stop the thread inside the service?

I have a checked button in my MainActivity. If that button is checked it should start the service but if a user unchecked the button I want to stop the service.
So in uncheck condition I have written this stopService(intentname); but the problem is the service is not stopping. Here is my code snippet:
Service Class
public class SimpleService extends Service
{
String selectedAudioPath = "";
private MyThread myythread;
public Intent intent;
public boolean isRunning = false;
long interval=30000;
#Override
public IBinder onBind(Intent arg0)
{
return null;
}
#Override
public void onCreate()
{
super.onCreate();
myythread = new MyThread(interval);
}
#Override
public synchronized void onDestroy()
{
super.onDestroy();
if(!isRunning)
{
myythread.interrupt();
myythread.stop();
isRunning = false;
}
}
#Override
public synchronized void onStart(Intent intent, int startId)
{
super.onStart(intent, startId);
if(!isRunning)
{
//this.intent = intent;
//System.out.println("the intent is" + intent);
myythread.start();
isRunning = true;
}
}
class MyThread extends Thread
{
long interval;
public MyThread(long interval)
{
this.interval=interval;
}
#Override
public void run()
{
while(isRunning)
{
System.out.println("Service running");
try
{
String myString = intent.getStringExtra("name");
if(myString == null)
Log.d("Service","null");
else
{
Log.d("Service","not null");
if(myString.equalsIgnoreCase("image"))
{
uploadImages();
Thread.sleep(interval);
}
else if(myString.equalsIgnoreCase("audio"))
{
uploadAudio();
Thread.sleep(interval);
}
}
}
catch (InterruptedException e)
{
isRunning = false;
e.printStackTrace();
}
}
}

You can't stop a thread that has a running unstoppable loop like this
while(true)
{
}
To stop that thread, declare a boolean variable and use it in while-loop condition.
public class MyService extends Service {
...
private Thread mythread;
private boolean running;
#Override
public void onDestroy()
{
running = false;
super.onDestroy();
}
#Override
public void onStart(Intent intent, int startid) {
running = true;
mythread = new Thread() {
#Override
public void run() {
while(running) {
MY CODE TO RUN;
}
}
};
};
mythread.start();
}
Source: Stopping a thread inside a service

Don't use Threads. Use AsyncTask instead.
public class MyService extends Service {
private AsyncTask<Void,Void,Void> myTask;
#Override
public void onDestroy(){
super.onDestroy();
myTask.cancel(true);
}
#Override
public void onStart(Intent intent, int startid) {
myTask = new AsyncTask<Void,Void,Void>(){
#Override
public void doInBackground(Void aVoid[]){
doYourWorkHere();
}
}
myTask.execute();
}
}
