问题 I have create an alarm manager that start a service every 5 second, the app is running well but after few hours the alarm manager stop running. Note that the application is not used by the user which mean that it is running on background without user interaction. Does any one knows how to start a service every some second without stopping ? AlarmManager am = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);

问题 I know this question has been asked before, but I've been over all of the answers I could find and still haven't been able to solve the problem. The issue is that when by BroadcastReceiver starts the IntentService onHandleIntent() isn't called. Weirdly enough the constructor does run (as I can see by the Log output). This is my code: NoLiSeA.class (This class contains the BroadcastReceiver that starts my service) public void toProcess(StatusBarNotification sbn) { LocalBroadcastManager

问题 In my Android app I start an IntentService from within an Activity by calling startService(new Intent(this, MyService.class)); And it works like a charm. I can move between Activies, press the Home button to switch to other apps... and it's still working. But if I remove my app from the recents screen, my service is stopped. How can I avoid this? In other words, how can I keep my service running even if my app is closed from recent apps? My service code is as follows: public class MyService

问题 After many hours of researching I am finally consulting official help. Why does not onHandleIntent() get called? Is there something wrong here?

问题 There's a REST service that I use to populate info in my database, that is later used by my app. I've read several threads on the matter, and now have to decide how I want the sync between the REST service and my DB to work. Think of an app that gets info from google finance APIs about stocks and stores it in a DB, displays the information when the app is launched, and sends notifications when specific events happen in the stock price. I already implemented the simple option of AsyncTask that
