'Android 12 is blocking the touches when using the <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

I am using <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" /> to show a pop up which overlay over other apps but android 12 is blocking the touches . As per the documentation it blocks the touch events how can i allow touches on android 12 .

Here is the link for android 12 behavioural changes touch events https://developer.android.com/about/versions/12/behavior-changes-all#untrusted-touch-events

Solution 1:^[1]

Try the following for the window type:

val windowType: Int = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY
} else {
    WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY
    WindowManager.LayoutParams.TYPE_SYSTEM_ALERT
}

See TYPE_APPLICATION_OVERLAY.

This is Kotlin, but you should be able to convert to Java easily.

Solution 2:^[2]

I don't think that's possible anymore. As stated in the docs, applications with window type:

TYPE_APPLICATION_OVERLAY

Aren't trusted and therefore won't be excepted from this protection.

How ever, they do write this:

Exceptions:

Completely transparent windows. The alpha property is 0.0 for the window.

So you can try removing:

PixelFormat.TRANSLUCENT

and instead set a real color, but with 0 alpha, such as (#00XXXXXX) might work but that's just a guess
