Trouble Shooting

Q: Why the log always shows 'No connection'?
A: Pleas check your network connection, and make sure your server supports HTTP 'HEAD' request, sometimes it works for certain path.

Q: Why it didn't check in the background?
A: You must manually open the app again after system restart, and make sure you (or the GC) didn't kill the app in the recent app list.

Q: Why it always shows 'Checked just now'?
A: The last check time is updated when app resumes, so you can check updates by turning the screen off and on, or by switching the app off and back.

Q: My battery is low, how can I turn the background check off?
A: Just terminate the app from the recent app list.
