After reading nearly every post in SO, and the developer docs, and various other sources, I thought I had got to a point where i could implement it. And so, I tried, and failed. Since then, I have trawled yet more forums and solutions, and I cannot seem to get it to update. I have an Update class that sets the AlarmManager: public class Update extends Service{ @Override public void onStart(Intent intent, int startId) { String currentTemp =

I tried with a persistent background service with a thread but it wasn't the right solution because of: battery consumption service termination, due to android memory management So I'm trying with AlarmManager.

Thanks! 回答1: When you set alarms you have two times: First trigger time
