VW Play Regio Scheme / Install Tests
Based on your results: file picker opens DocumentsUI, direct downloads do not appear, waze:///geo: work,
and intent:// does not. This page tests whether APK/file/package schemes can reach another Android handler.
test.apk in this folder is intentionally not a real APK. If Package Installer opens and says parsing failed,
that is a useful positive result. Do not install unknown APKs yet.
