Maybe my local android sdk was too new and did not compatible with the android project.

[freakboy3742]

This appears to be an issue with a backwards incompatible change in the Android version of Gradle, and the Gradle task definition for Android native libraries. We've corrected this in an updated template; let us know if you continue to have problems.

I redo the tutorial, but failed with another error, android template does not support python 3.10?

@liudonghua123 Correct - Python 3.10 is not yet supported on Android. Python3.9 is the most recently supported version.

[liudonghua123]

@freakboy3742 Thanks, I installed python 3.9 and now it worked.
