Targetting android 29 issues a warning on new device that the apk contains security breaches. I've updated the target to Android 34 and made the necessary changes to build the apk. We still install build-tools and platform version 29 because version 34 has a bug in `dx` (renamed to `d8`) where it fails to link classes.dex
