Not sure what is going on, but following the document on the Clover site on the sideloading akp file to a DevKit, but unsuccessful.
here are the error messages that I got while trying adb install an apk file via cmd line:
adb: failed to install app-clover-debug.apk: Failure [INSTALL_PARSE_FAILED_UNEXPECTED_EXCEPTION: Failed to collect certificates from /data/app/vmdl453800795.tmp/base.apk: Failed reading lib/x86_64/libopencv_java3.so in android.util.jar.StrictJarFile@86c91f5: Size mismatch on inflated file: 43441305 vs 43441344]
