Hide tap jacking alerts on android app below Android 12

Question

I want to hide tap-jacking alerts in my Android app. I was able to do it on Android 12 and above by using getWindow().setHideOverlayWindows(true);. Can someone help me achieve this on versions below Android 12? Is there any alternative method to setHideOverlayWindows(true) for versions below Android 12?

I also added below property in xml's rootview.

android:filterTouchesWhenObscured="true"

Answer 1

Before Android 12, there's only one permission android.permission.HIDE_NON_SYSTEM_OVERLAY_WINDOWS which is intended for system app.

so basicly there's no trivial way to do that
