Menu
I am making an app in which one of the features, the users location is updated once every 10 seconds. So far the app is not updating it's location because the activity is paused and restarted before the location is retrieved. I don't understand why the activity is being restarted. My best guess is, since there is not a whole lot going on, the OS is pausing the activity, but what will trigger the activity to restart? I have attempted to built the app before, and then I restarted from scratch because I made too many mistakes but even then, I have not seen this problem before.

Is the requested permission included in the manifest?
This is an old question, but I found it when I ran into the same problem:
In my case, the line where permissions were requested was causing the problem.
ActivityCompat.requestPermissions(mParentActivity,
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
MY_PERMISSION_ACCESS_FINE_LOCATION);
I was requesting the CALL_PHONE permission, but had removed it (because I wasn't using it anymore), but did not remove the permission check. Two possible solutions:
Add the requested permission to the manifest.
uses-permission android:name="android.permission.CALL_PHONE"
Remove the line requesting the permission (only if you don't need it anymore, of course.)
