App crash on Huawei P8 Lite; works fine on other devices

Question

My app doesn't start on Huawei P8 Lite, but it works fine on other devices. I searched for the problem a long time, but I couldn't find a solution that works.

My app ran all the time without problems. Then I fixed a few problems and got the startup crash on Huawei P8 Lite. I don't get it.

LogCat:

Answer 1

After some research I found out that Huawei doesn't show you everything inside LOGs when you upgrade to Android M on Huawei P8 Lite (I tested it on Mate 20 Pro with Android P and I see everything).

So the actual problem is always hidden under these strange Huawei Logs

To show everything in logcat you have to type inside dialer special code:

*#*#2846579#*#*

Then you should see this settings screen:

Go to Background Settings

Click on LOG Settings and adjust logs to your needs
