android run service in background from time to time when the application is running

I am building an android app and when it is running I need to make a call to the my web server at each minute if the user is connected to a certain network.

I plan to use a service to make that call but how do I call it at each minute?. I think i need to use alaarm manager but where do I initalize it? in my start activity? I only need to execute the service when my app is running.

Thanks for your help.

If you want to call server only if app is running then no need to use alarm manager. there are other options like

CoundDownTimer

Thread

I prefer CoundownTimer in that scenario and you can use like this

CountDownTimer countDownTimer = new CountDownTimer(1000000, 60 * 1000) {

    @Override
    public void onTick(long millisUntilFinished) {
            // Do something on a tick.
    }

    @Override
    public void onFinish() {
        // Do something, maybe?

        this.start();
    }
};
countDownTimer.start();

in Activity:

@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   TestAlarmMessageReceiver almesr = new TestAlarmMessageReceiver(this, time);
}

BroadcastReceiver:

public class TestAlarmMessageReceiver extends BroadcastReceiver {


    public TestAlarmMessageReceiver() {
    }

    public TestAlarmMessageReceiver(Context context, int timeout) { //timeout in seconds
        AlarmManager alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(context, TestAlarmMessageReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 
                PendingIntent.FLAG_CANCEL_CURRENT);
        Calendar time = Calendar.getInstance();
        time.setTimeInMillis(System.currentTimeMillis());

        alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), 
                timeout*60*1000, pendingIntent);
    }

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        arg0.startService(new Intent(arg0, TestMessageService.class));
    }

}

Service:

public class TestMessageService extends Service {

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        messageUpdateTask();
        return super.onStartCommand(intent, flags, startId);
    }

    private void messageUpdateTask(){
        GetMessagesUpdateAsyncTak getMessUpd = new GetMessagesUpdateAsyncTak();
        getMessUpd.execute(this);
    }
}

Try this ::

You can call this timer in your activity where you want it

private Timer autoUpdate;
@Override
public void onResume() {
    super.onResume();
    autoUpdate = new Timer();
    autoUpdate.schedule(new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                public void run() {
                    //call your service from here
                }
            });
        }
    }, 0, 60000);//set time interval according to your requirement
}

Feel free to ask if you have any query :)

Call your web server using AsynTask http://developer.android.com/reference/android/os/AsyncTask.html

In onPost method in AsynTask class wait for one minute and call AsynTask.

You can call AsynTask by using below code :

  BLSyncingProcedure objSyncingProcedure=new BLSyncingProcedure();
        objSyncingProcedure.execute(HomeScreen.this);

BLSyncingProcedure is your AsynTask class name.
