there is no error

Ans what's the printer resultCode ? It's difficult to debug without the error. I will advice you to recompile library with the newest Core libraries and test again.

i think it's got to do with new permissions maybe

What permissions do you have in the manifest ?

I wish there was an error

when I install on new device it's crush without error

no such thing. When a app crashes there must be an error in the log. maybe in the unfiltered log

I have fixed the problem with run time permission read and write external storage
