Thanks a lot.I retryed the Google version then overwrite the installation with the forum version,it can works well.Thank you!

I have checked my App Launch settings,and my rom might not be the same as yours.I don't know what went wrong.I think i can only use the version 820.

App exits directly and the background is over

Version 820 could work when it's locked,but 821 and 822 couldn't.I have checked all my settings include bettery setting and so on.

All outputs...

I think you misunderstood what I meant.The problem only occurs in version 821.Version 820 can work when my device is locked.And i have checked the system setting.

The problem only appears in version 821

I have checked it several times,it didn't work

Thanks for the update,but on my device there is a problem.When my device is locked the player may shutdown soon.Before this revision it wasn't that.My device is Huawei Mate10.Thanks a lot.
