May be somebody know how fix this issue, or can advise another emulator, where i can run kivy application?

Thanks.

Your app is compiled for arm, but the emulator is x86 only. You can probably use an arm emulator, or python-for-android does support x86 (--arch=x86) but buildozer doesn't expose this option.

Many thanks for your answer!

How i understand, i can use `--arch=x86` just in 32 bit system?
