Launching to android phone error

When launching to android phone,app opens splash screen than closes?
In log 2 red errors
[GameActivity] java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol “__aeabi_memcpy” referenced by “/data/app/com.YourCompany.puzz-1/lib/arm/”

Any ideas?

Are you targeting the correct version of android? It appears this error can be generated by targetting a higher version of the API than the device you are testing it on.

If you are not using any third party plugin then the best way the only reason it could be is GPU.try to buiuld for android Multi and check again.
if still the crash occurs then try to change gradle verion in your Engine Build folder under hava directory to 6.5 .hopefully it will make it work.
