问题 I have created a service to fetch current location of the device in periodic intervals. I want the service to run in the background even if the app is cleared from recently opened apps. Currently the service runs in background only until app is present in the recently opened apps but stop immediately when app is swiped off (or killed in some other way). I have tried all sort of help available in stack overflow yet I am unable to solve this. Please help. Here is my code for the service.

问题 The life cycle diagram of an Activity on an android does not guarantee that onDestroy() would be called, but that the process may be killed and the Activity is removed abruptly.

问题 I want to create a service which will run on a separate thread (not on UI Thread), so I implemented a class which will extend IntentService. But I haven't got any luck. Here is the code. public class MyService extends IntentService { public MyService(String name) { super(name); // TODO Auto-generated constructor stub } @Override public IBinder onBind(Intent arg0) { // TODO Auto-generated method stub return null; } @Override public void onCreate() { // TODO Auto-generated method stub super
