Cancel AlarmReceiver from service class

Question

I have class for call myService with alaram Manager. From mainActivity this is my code to set alarm manager.

Intent downloader = new Intent(context, AlarmReceiver.class);
                downloader.putExtra("limit", limit.getSelectedItem().toString());
                downloader.putExtra("delay",perMin.getSelectedItem().toString());
                downloader.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);    `pendingIntent = PendingIntent.getBroadcast(context, 0, downloader,PendingIntent.FLAG_CANCEL_CURRENT);
alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
int delay = Integer.parseInt(perMin.getSelectedItem().toString());
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,10 * 1000, delay * 1000, pendingIntent);

and here my alarm receiver class public class AlarmReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    Intent update = new Intent(context, IntervalService.class);
    Log.i(tag, "Call service from Alaram Receiver");
    context.startService(update);
}}

I know when i want to cancel alarm manager from main activity easily call alarmManager.cancel(pendingIntent) but i want to cancel alarm manager to complete my service task and after that set again like as above.

Just use another broadcast but with an Intent extra indicating the alarm should be cancelled. — Squonk

Just modified your code,

public void setAlarmManager(boolean cancel){

PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0,downloader,PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
int delay = Integer.parseInt(perMin.getSelectedItem().toString());
if(!cancel)
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,10 * 1000, delay * 1000, pendingIntent);
else
alarmManager.cancel(pendingIntent);

}

call this function when needed,

to Start: setAlarmManager(false);

to Cancel: setAlarmManager(true); //Call this function in Service

Try, this may work. Thanks.
