add an aar file, the app will crash.

I built handtracking on Android. Referred to the above site to create an aar file. Above is the composition of the aar file I made. When I add the aar file to the lib folder and start the app, the app crashes. Is there another way to compile the aar file?

Hi @MakeMeCookie, Would you let us know if you are following the target mentioned here to build and run the hands solution? Further we need information about the device which you using in the physical device or in android emulator? However, We suggest that to fill the template to understand more on issue.

Added .pbtxt and tflite files above. Do you have any missing AAR files? I use Galaxy S9+, Android 10, and api30.
