Guys, I think a mixer having an app is a bad idea.
1. With the APK, telemetry might be collected by the Android subsystem about the app's metadata and sent to Google.
2. You are no longer anonymous when using an app unless it has a Tor router built-in.
3. Even when you make an APK, you'll never be able to make an iOS app (except in the EU apparently), however, progressive web apps work just fine on all platforms. So why not take that approach instead?
