I am using sync adapter on my app to perform periodic sync . But the problem is when a sync is running , and I close the app at that time , sync stopped . As far as I know sync adapter always run on background , closing the app won't affect sync process . But why is this happening ? How can I overcome this problem ?

As far as having it run continuously goes, keep in mind that by design, the Android system may terminate your service process at any time. You can influence this a bit, but you cannot prevent the system from killing your service.

For some code, look here for example:
