Note:

There are currently issues with Android 10. Android 10 is not backwards compatible. So some loggers are not detected anymore on Android 10. So better avoid upgrading until we have a fix.

Building the .apk file

The build uses the gradle environment. A ./gradlew build should do.

git clone git@codeberg.org:kollo/USBDataloggerreader-Android.git

then do a cd USBDataloggerreader-Android ./gradlew build (Enter passwords for the keystore) (the compile process will take a while.)

The apk should finally be in build/outputs/apk/USBDataloggerreader-Android-release.apk
