Android 9 (Pie), Context.startForegroundService() did not then call Service.startForeground(): ServiceRecord

After too much struggle with this crash finally, I fixed this exception completely and find the solution.

Make sure that have done this stuff in your service I list them as below : (some of this stuff are repetitious as mentioned in another answer I just write them again).

1- Call

startForeground()

in both onCreate and onStartCommand.(it's ok to call startForeground() many times)

  @Override
public void onCreate() {
    super.onCreate();
    startCommand();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent == null) {
        return START_NOT_STICKY;
    }
    final int command = intent.getIntExtra(MAIN_SERVICE_COMMAND_KEY, -1);

    if (command == MAIN_SERVICE_START_COMMAND) {
        startCommand();
        return START_STICKY;
    }
    return START_NOT_STICKY;
}

 private void startCommand() {
    createNotificationAndStartForeground();
    runningStatus.set(STARTED);
}

2- Stop your service using

context.stopService()

, there is no need to call stopForeground() or stopSelf().

  try {
        context.stopService(
                new Intent(
                        context,
                        NavigationService.class
                )
        );
    } catch (Exception ex) {
        Crashlytics.logException(ex);
        LogManager.e("Service manager can't stop service ", ex);
    }

3- Start your service using

ContextCompat.startForegroundService()

it will handle different API versions.

   ContextCompat.startForegroundService(
            context,
            NavigationService.getStartIntent(context)
    );

4- If your service has actions ( need pending Intents ) handle your pending intents with a Broadcast receiver rather than your current service( it will call your service on Create() and can be dangerous, or use PendingIntent.FLAG_NO_CREATE) , it's a good practice to have a specific Broadcast receiver for handling your service notification actions, I mean create all your pending intents using PendingIntent.getBroadcast().

    private PendingIntent getStopActionPendingIntent() {
    final Intent stopNotificationIntent = getBroadCastIntent();

    stopNotificationIntent.setAction(BROADCAST_STOP_SERVICE);

    return getPendingIntent(stopNotificationIntent);
}

private PendingIntent getPendingIntent(final Intent intent) {
    return PendingIntent.getBroadcast(
            this,
            0,
            intent,
            0
    );
}

new NotificationCompat.Builder(this, CHANNEL_ID)
            .addAction(
                    new NotificationCompat.Action(
                            R.drawable.notification,
                            getString(R.string.switch_off),
                            getStopActionPendingIntent()
                    )
            )

5- Always before stop your service make sure that your service is created and started (I Create a global class that has my service state)

  if (navigationServiceStatus == STARTED) {
            serviceManager.stopNavigationService();
        }

6- Set your notificationId to a long number such as 121412.

7- Using NotificationCompat.Builder will handle different API versions you just need to create notification channel for Build versions >= Build.VERSION_CODES.O.(This one is not a solution just make your code more readable)

8- Add

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" /> 

permission to your manifest. (this one is mentioned in android docs) Android Foreground Service

hope it helps :))

I was waiting my crash report to share the solution. I didn't get any crash or ANR almost 20 days. I want to share my solution. It can help those who encounter this problem.

In onCreate() method

• First of all, my app is a media application. I didn't implement the mediasession yet. I'm creating a notification channel in the top of onCreate(). Official doc
• I'm calling Service.startForeground() method after Context.startForegroundService() method. In my prepareAndStartForeground() method.

  Note: I don't know why but ContextCompat.startForegroundService() doesn't work properly.

For this reason, I've added manually same function to my service class instead of calling ContextCompat.startForegroundService()

private fun startForegroundService(intent: Intent) {
    if (Build.VERSION.SDK_INT >= 26) {
        context.startForegroundService(intent)
    } else {
        // Pre-O behavior.
        context.startService(intent)
    }
}

---

prepareAndStartForeground() method

private fun prepareAndStartForeground() {
    try {
        val intent = Intent(ctx, MusicService::class.java)
        startForegroundService(intent)

        val n = mNotificationBuilder.build()
        // do sth
        startForeground(Define.NOTIFICATION_ID, n)
    } catch (e: Exception) {
        Log.e(TAG, "startForegroundNotification: " + e.message)
    }
}

---

It's my onCreate()

override fun onCreate() {
    super.onCreate()
    createNotificationChannel()
    prepareAndStartForeground()
}

---

My onStartCommand()

override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
    if (intent == null) {
        return START_STICKY_COMPATIBILITY
    } else {
        //....
        //...
    }
    return START_STICKY
}

---

onRebind, onBind, onUnbind methods like these

internal var binder: IBinder? = null

override fun onRebind(intent: Intent) {
    stopForeground(true) // <- remove notification
}

override fun onBind(intent: Intent): IBinder? {
    stopForeground(true) // <- remove notification
    return binder
}

override fun onUnbind(intent: Intent): Boolean {
    prepareAndStartForeground() // <- show notification again
    return true
}

---

We need to clear something when onDestroy() calling

   override fun onDestroy() {
    super.onDestroy()
    releaseService()
   }

---

private fun releaseService() {
    stopMedia()
    stopTimer()
    // sth like these
    player = null
    mContext = null
    afChangeListener = null
    mAudioBecomingNoisy = null
    handler = null
    mNotificationBuilder = null
    mNotificationManager = null
    mInstance = null
}

I hope this solution works properly for you.

The Android Service component is a bit tricky to get working properly, especially on later Android versions where the OS adds additional restrictions. As mentioned in other answers, when starting your Service, use ContextCompat.startForegroundService(). Next, in Service.onStartCommand(), call startForeground() immediately. Store the Notification you want to show as a member field and use that unless it is null. Example:

private var notification:Notification? = null
override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
    if (notification == null) {
        notification = createDefaultNotification()
    }
    startForeground(NOTIFICATION_ID, notification)

    // Do any additional setup and work herre

    return START_STICKY
}

Always return START_STICKY in your Service. Anything else is probably the wrong thing, especially if you're doing a audio player of any kind. In fact, if you're doing an audio player, you shouldn't implement your own Service but use MediaBrowserServiceCompat (from AndroidX) instead.
