Android - Window Flags

Is there a way to detect when a window flag triggered? Let's just say I have a WindowManager.LayoutParams.FLAG_SECURE. How do I detect it when I triggered it? I tried googling the

Solution 1:

In your activity simply override onWindowAttributesChanged, in Kotlin:

class MyActivity: AppCompatActivity() {

    private var lastKnownWindowFlags = 0

    override fun onWindowAttributesChanged(params: WindowManager.LayoutParams) {
        if (params.flags != lastKnownWindowFlags) {
            // New window flags!
            lastKnownWindowFlags = params.flags
        }
    }
}
