I want to use a service that run in background indefinitely and call a method every 10 minute and its running even app killed
How to create it?
For "how to work with services", see
Services - Android
Services in Android - Vogella
Here is a clear solution that focus on "every 10 minutes" part using AlarmManager: https://stackoverflow.com/a/10222390/2591556
Assuming you have a Running Service
User AlarmManager to run Service every 10 minutes
AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, YourService.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 600000, pi); // Millisec * Second * Minute
}
You can do by using service as follows
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
//performe the deskred task
}
}, 10minutes time in milisecods);
// If we get killed, after returning from here, restart
return START_STICKY;
}
This service will get started automatically even if app get killed, and postdelayed will run
You can use the Alarm manager which will be called after every 10 mins
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Random random = new Random();
int m = random.nextInt(9999 - 1000) + 1000;
Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
notificationIntent.setClass(this,AlarmReceiver_.class);
notificationIntent.addCategory("android.intent.category.DEFAULT");
PendingIntent broadcast = PendingIntent.getBroadcast(YourClass.this, m, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() + 300000L,
600000L, broadcast);
ManiFest receiver Code where you will get a receiver response
<receiver android:name="com.yourpackage.AlarmReceiver_"
>
<intent-filter>
<action android:name="android.media.action.DISPLAY_NOTIFICATION" />
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<action android:name="android.intent.action.REBOOT" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
You will have to create Receiver where you will receive data as an above-specified name of AlarmReceiver_.class
you could write a background Service: Running in a Background Service
and start the service every 10-11 min (cause of AlarmManager power saving behaviour), or with exact timing (needs to shedule next execution every time) with AlarmManager.setExact
Example:
private static PendingIntent createClockIntent(Context context) {
Intent intent = new Intent(context.getString(R.string.widget_broadcast_clock_update));
PendingIntent pendingIntent = PendingIntent.getBroadcast(context.getApplicationContext(), 1,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
return pendingIntent;
}
public static void startClockAlarm(Context context) {
AlarmManager alarmManager = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
clockIntent = createClockIntent(context);
alarmManager.setRepeating(AlarmManager.RTC, 0,
600000, clockIntent);
}
