[SOLVED] Why won't the app launch on android 5.1?

Question

Android

Wrote the game. Decided to test it out before posting. I threw off the apk file to my friends. It so happened that the application did not run on andoird 5.1, although everything works fine on earlier versions. What could be the problem?
Did not work on two meizu m1 note phones with android 5.1 and on xiaomi mi4c with android 5.1.1
On versions below, including 5, it works on all phones. It also works on meizu mx4 with 4.4 android , so I think that the problem is not in the phone, but in the android version.

UPDATE OF THE QUESTION
The problem went away when I built the project on windows 8.1
Before using xubuntu 14.04 LTS

Answer 1

Somewhere there is an error.

Answer 2

Here is the change log https://paste.teknik.io/1010 of what has changed in 5.1 relative to 5.0
In general, I advise your friends (or you) to install adb and after an error execute adb logcat > log.txt
After, if you don’t understand yourself what is the error (which I very much doubt), throw the log here

Answer 3

/data/app/com.game-1/lib/arm64/libgdx.so - check for libraries for this architecture. well, or write to the libgdx developer, with a description of the problem for arm64. I also recommend checking it on other architectures with the same OS. In general, there I see an attempt to load classes designed for a 32-bit system. And you most likely have arm64.

Answer 4

Something is not working
