Android Foreground Service Slow If Device Is Idle

I have an android foreground service, called with the notification. In the service Im just logging every 10 seconds 'Tick tack', but the priority of the service is navigate in a we

Solution 1:

I have made this library the other day for something similar service in background and foreground

And its working absolutely fine with no problems.

The reason I choose to run it with AlarmManager is that the AlarmManager is a great candidate for scheduling if an application needs to perform a local event + allows an application to schedule tasks that may need to run or repeat beyond the scope of its lifecycle. This allows the application to perform some function even after the application process or all of its Android components have been cleaned up by the system.

UPDATE

Call this method to start the service

publicvoidcall(int Value_in_seconds) {
        if (Value_in_seconds == (int) Value_in_seconds) {
            // Number is integer
            Long time = new GregorianCalendar().getTimeInMillis() + Value_in_seconds * 1000;
            // create an Intent and set the class which will execute when Alarm triggers, here// ServiceReciever in the Intent, the onRecieve() method of this class will execute when// alarm triggers
            Intent intentAlarm = new Intent(context, ServiceReciever.class);
            // create the object
            AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
            //set the alarm for particular time
            alarmManager.set(AlarmManager.RTC_WAKEUP, time, PendingIntent.getBroadcast(context, 1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
        } else {
            Toast.makeText(context,  context.getString(R.string.intValue), Toast.LENGTH_SHORT).show();
        }
    }

Create ServiceReciever Class

publicclassServiceRecieverextendsBroadcastReceiver {

    @OverridepublicvoidonReceive(Context context, Intent intent) {
        //call the method here

    }
}

inside your manifest

<application><receiverandroid:name="hossamscott.com.github.backgroundservice.ServiceReciever"android:process=":ff"android:exported="true"android:enabled="true"></receiver><serviceandroid:name="hossamscott.com.github.backgroundservice.BackgroundTask"/></application>

And thats should be it, tho if you like to run it in Thread Than you can add the next lines

publicclassBackgroundTaskextendsService {

    privateboolean isRunning;
    privateContext context;
    privateThread backgroundThread;


    @Overridepublic IBinder onBind(Intent intent) {
        returnnull;
    }

    @OverridepublicvoidonCreate() {
        this.context = this;
        this.isRunning = false;
        this.backgroundThread = newThread(myTask);
    }

    privateRunnable myTask = newRunnable() {
        publicvoidrun() {
            // Do something herenewHandler(Looper.getMainLooper()).post(newRunnable() {
                @Overridepublicvoidrun() {
                    // do your logic here
                }
            });
            stopSelf();
        }
    };

    @OverridepublicvoidonDestroy() {
        this.isRunning = false;
    }

    @Overridepublic int onStartCommand(Intent intent, int flags, int startId) {
        if (!this.isRunning) {
            this.isRunning = true;
            this.backgroundThread.start();
        }
        returnSTART_STICKY;
    }

}

And to call this class edit ServiceReciever to be like this

@OverridepublicvoidonReceive(Context context, Intent intent) {
        //call the method hereIntentbackground=newIntent(context, BackgroundTask.class);
        context.startService(background);
    }
