Question

After adding Application Overlay using WindowManager.LayoutParams in Oreo, I'm not able to click on any part display on phone, Touch event is not considered. Here is my code

 int LAYOUT_FLAG;
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
                } else {
                    LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;
                }


                layoutParams = new WindowManager.LayoutParams(
                        1,
                        1,
                        LAYOUT_FLAG,
                        WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH
                                | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                                | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
                                | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                                | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
                                | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
                                | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION

                                | WindowManager.LayoutParams.FLAG_SPLIT_TOUCH

                                | WindowManager.LayoutParams.FLAG_ALLOW_LOCK_WHILE_SCREEN_ON
                        ,
                        PixelFormat.TRANSPARENT
                );
