通过使用标志一次显示AlertDialog

Question

I am sending data route,long, lat, mac to the Server very 10 seconds. Often the route is 0. In this case, the server will be asked for the route. As soon as the app has the route from the server , Checkbox AlertDialog appears to confirm the result by the user. Then the route will be envloped with the other data Long, lat, mac as JSOn string and transmitted to the server again.

I am facing Problem that the alert Dialogs will pile up when the user does not interact with the Dialog immediatly. What I am trying to achieve is to pop up the Dialog window just once when the server provides the app with route and not very 10 seconds with the Response from the server since when the user reacts too late he has to confirm all these Dialog Windows also after 1 Minute he has to confirm 6 Dialog Windows. Therefor, I am using flag to reach that but the problem currently with flag is when it is set once to false it is not possiable to enter the stop_popup method again till the app is restarted gain.

Is there anyway to set the flag variable to true after 10 minutes without interupting sending the data to the server?

public class TrackingService extends Service implements AsyncTaskCallback  {

    boolean flag = true;
      ......
        @Override
    public void onAsyncTaskFinished(ArrayList<Integer> routeList, double distance) {
        if (distance <= 15 && speed <= 4 && flag== true) {
            popup_dialog(routeList);

        } else {
            route_number = routeList.get(0);
            System.out.println("The route number is: " + route_number);
        }

    }


    private void popup_dialog(final ArrayList<Integer> routeList) {


        int routeListSize = routeList.size();
        flag = false;

        if (routeListSize > 0) {
      //AlertDialog.Build code
   }
  }
}

Use a postDelayed Handler that turns flag = true after 10 minutes.

private void popup_dialog(final ArrayList<Integer> routeList) {
    int routeListSize = routeList.size();

    flag = false;

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            flag =true;                       
        }
    }, 10 * 1000 * 60);  // 10 minutes (60 sec * 1000 milliseconds)

    if (routeListSize > 0) {
        //AlertDialog.Build code
}
