问题 I am calling a background Service at interval of 30 min to read the latitude/longitude of current location and sending it to server by POST API . I am using setRepeating() method of AlarmManager class to schedule alarm every 30 minutes. But some times the alarm is getting missed and service is not called.

问题 Looks like force stop should prevent app from running and it's even disable all app's alarms. However I found that notification in Google Calendar still shown fine even after force stop, and I all the time see Instagram app running, even when I kill it, it's just restart automatically and it's once again there. So, what is a way to make app running constantly? I'm doing app with reminders and need to show notifications in specific time, regardless how app was previously closed before. 回答1: If

问题 I use Volley library to connect with server in my app. Now, I have to send request in background every 5 minutes also when app is not running (killed by user). How should I do it? With background services, AlarmManager (Google says that it isn't good choice for network operations) or something else? Or maybe SyncAdapter will be good for it? 回答1: You can use a TimerTask with scheduleAtFixedRate in a service class to achieve this, here is an example of Service class, you can use it public class

问题 I am working on a widget application where I have to perform some task in every one minute. So, I am using AlarmManager to achieve this. But no matter whatever I set the interval time, its being repeated in every 5 seconds. I am using AlarmManager like this: final AlarmManager alarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); alarm.cancel(pendingIntent); long interval = 60000; alarm.setInexactRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime(),

问题 I've been seeing some strange issues using the Alarm manager in Android, despite the fact that I'm using RTC (non Wakeup) the phone will reliably send the PendingIntents on the correct repeating intervals. Details of my test Device is not charging, just sitting on my nightstand while I slept My service woke up on its repeat interval (30 minutes, an extreme I know) EVERY TIME The service logged its activity in a file so I could read it in the morning Now from my understanding the phone should

问题 I am working on a app locker which has some background services (to lock apps). I am using Xiaomi Redmi Note 4g for the development. The MIUI has an in-built task manager which can be used to kill running apps. When I kill apps with this, all services, broadcastreceivers and alarmmanagers are getting removed (as expected from a task manager). My requirement is to prevent my background services from getting cleared from task-killers, but if the user navigates to settings and force closes, the

问题 I use an AlarmManager to start a service. When i set up the AlarmManager i use the PendingIntent and use a unique requestCode which is equal to a id row in my database. PendingIntent pendingIntent = PendingIntent.getBroadcast(SettingsActivity.this, lecture.getId(), myIntent, 0); How can I retrieve that id in my service when it starts?
