With Android Q (API 29) Google changed the Launcher icon visibility behaviour. Even if you disable your Launcher Activity or completely remove the android.intent.category.LAUNCHER <intent-filter> from all your Activities, the app will appear in the launcher and open the Android OS app settings, with the exception of:

• Packages that don't declare any permissions in their respective manifest files
• System apps
• Apps that don't contain any components inside theirrespective manifest's tag
