You don't get any data because there is no updated aauto-vex-vag version. The latest available build and source code of vex-vag is using aauto-vex-base 3.1. This is the version before schema was introduced.I'm working on a v2 for the app. Currently I'm struggling with the latest version of Martoreto's AA stats which doesn't give me any data...
Your last apk release (45B) also used version 3.1 of base so if you install it and run, it gets the data from latest aauto-vex-vag (2.2 release) without any issues, as they both share the same vex-base.
But since you have updated the gradle to link to newer version of aauto-vex-base (v4.3) the app uses the updated version (including e.g. the schema concept) to get data from aauto-vex-vag, which the latter does not yet implement and thus is unable to provide data in proper form to the app.
You should also be able to see the line "Provider schema elements count: 0" in logcat, which proves that the app is not able to get any schema information from the vex-vag.
