Android Application : How do I get touch event on Home Screen when the app in Background Action

Question

Using WindowManager, I make the app floaintView in home screen like Facebook Messenger.

MotionEvent allows to move the Floated View. I'd like to set up WindowManager Flag and get a touch event for a screen other than Floating, but it's not working...

When I touch the floating view, It works well. By calling OnTouchListener, ACTION_DOWN ACTION_UP,

When I touch outside the Window( Home Screen), I Want it works well both Doing other Job(Touching other App) and Calling Listener Please anyone guide me how I can get touch event in my app so I can do some task. I used three all flags FLAG_WATCH_OUTSIDE_TOUCH FLAG_NOT_TOUCH_MODAL
FLAG_NOT_FOCUSABLE

FLAG_NOT_FOCUSABLE |FLAG_NOT_TOUCH_MODAL
On the Home screen, it touchs of the rest of the window, but fails to invoke the touch of the OnClickListener.

FLAG_WATCH_OUTSIDE_TOUCH Touch other than Floating View is blocked.

@SuppressLint("ClickableViewAccessibility") override fun onCreate() { super.onCreate() if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) startMyOwnForeground() else startForeground( 1, Notification() )

 //Inflate the floating view layout we created
 mFloatingView = LayoutInflater.from(this).inflate(R.layout.test, null)

 val LAYOUT_FLAG: Int
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
     LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY

 } else {
     LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE

 }

 params = WindowManager.LayoutParams(
     WindowManager.LayoutParams.WRAP_CONTENT,
     WindowManager.LayoutParams.WRAP_CONTENT,
     LAYOUT_FLAG,
     WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE or  WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL or WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
     PixelFormat.TRANSLUCENT
 )

 //Specify the view position
 params!!.gravity =
     Gravity.TOP or Gravity.LEFT //Initially view will be added to top-left corner
 params!!.x = 0
 params!!.y = 100

 //Add the view to the window
 mWindowManager = getSystemService(WINDOW_SERVICE) as WindowManager
 mWindowManager!!.addView(mFloatingView, params)

 var test = mFloatingView!!.findViewById<RelativeLayout>(R.id.wrap_container)
 with(test) {
     setOnTouchListener(object : View.OnTouchListener {
         private var initialX = 0
         private var initialY = 0
         private var initialTouchX = 0f
         private var initialTouchY = 0f
         override fun onTouch(v: View?, event: MotionEvent): Boolean {
             Log.d("aa", "aa")
             when (event.action) {
                 MotionEvent.ACTION_DOWN -> {
                     Log.d("ACTION_DOWN", "ACTION_DOWN")
                     //remember the initial position.
                     initialX = params!!.x
                     initialY = params!!.y

                     //get the touch location
                     initialTouchX = event.rawX
                     initialTouchY = event.rawY

                     return true
                 }
                 MotionEvent.ACTION_UP -> {
                     Log.d("ACTION_UP", "ACTION_UP")

                     val Xdiff = (event.rawX - initialTouchX).toInt()
                     val Ydiff = (event.rawY - initialTouchY).toInt()


                     //The check for Xdiff <10 && YDiff< 10 because sometime elements moves a little while clicking.
                     //So that is click event.
                     if (Xdiff < 10 && Ydiff < 10) {
                         val intent = Intent(applicationContext, MainActivity::class.java)
                         intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
                         intent.putExtra("fromwhere", "ser")
                         startActivity(intent)
                     }
                     return true
                 }
                 MotionEvent.ACTION_MOVE -> {

                     Log.d("ACTION_MOVE", "ACTION_MOVE")
                     //Calculate the X and Y coordinates of the view.
                     params!!.x = initialX + (event.rawX - initialTouchX).toInt()
                     params!!.y = initialY + (event.rawY - initialTouchY).toInt()


                     //Update the layout with new X & Y coordinate
                     mWindowManager!!.updateViewLayout(mFloatingView, params)
                     return true
                 }
                 MotionEvent.ACTION_OUTSIDE -> {

                     Log.d("ACTION_OUTSIDE", "ACTION_OUTSIDE")
                     //Calculate the X and Y coordinates of the view.
                     initialX = params!!.x
                     initialY = params!!.y

                     //get the touch location
                     initialTouchX = event.rawX
                     initialTouchY = event.rawY

                     return true
                 }
             }
             return false
