问题 i am developing an android app to show notifications.How can i poll a webservice at finite interval (say 10 min interval) to check for any update and show as notification in android notification panel. 回答1: You do not need a service.

Please see my answer on a similar question that uses an Alarm from the AlarmManager:

问题 I have implemented the alarm manager to wake up the background services every 15 mins periodically. It is working fine, but since the inclusion of DOZE mode Android 6.0, the seems like behaving strange and not waking up in every 15 mins. Although, I am using the method alarm.setExactAndAllowWhileIdle(), but still not working in Idle state here is my method for implementing Alarm Manager private void serviceRunningBackground() { final Intent restartIntent = new Intent(this, service.class);
