@jsulm Thanks for your suggestion.

I solved that, as i understand it, the problem is Qt 6.0.

In Qt setup folder, android architectures(armv7, v8, x86 etc.) are in directory seperately. But Qt Version 5.14.2 merge all android architectures in one folder. Now, i can create common single kit for all android archs.

And it helped to me: https://stackoverflow.com/questions/67291379/unable-to-create-android-kits-using-qt-creator
