I also tried installing everything from android studio not using qt creator for SDK setup. I always get the same error.
Ok, i found out how to fix it. Following qt tutorial they install NDK 21 and for their version it might work but as im using android 34 i need to use NDK 17. After deleting whole Android folder where SDK is and setting everything up again but with NDK 17 it worked for me.
what i followed
