Android Question [Solved]Transparent app covers device icons

[anOparator]

I put together an app with a Transparent background that changes the device wallpaper every 2 hours.
It steps thru the List of images but I can't click any Device Screen icons (the Phone OR webBrowser).

In the Service module that updates the wallpaper:

Sub Service_Start (StartingIntent As Intent)
   StartServiceAt(Me, DateTime.Now + 10000, True)  ' 2 hours, 10 seconds for testing
   If Starter.gtum = Starter.aWallPicX.Size - 1 Then
       Starter.gtum = 1
       Log("    MAX MAX MAX ")
   Else
       Starter.gtum = Starter.gtum + 1
       Log("   min MJN min MIN")
   End If
   Log("      img # = " & Starter.gtum)
   Log("picture name  = " & Starter.aWallPicX.Get(Starter.gtum))
   CallSubDelayed(Main, "changePicture")    ' get next Img!
   StartServiceAt(Me, DateTime.Now + 10000, True)  ' 2 hours, 10 seconds for testing
   'StartServiceAt(Me, DateTime.Now + 1860000, True)  ' 2 hours, 31 minutes for testing.
   Log(" ")
End Sub

In Main:

Sub changePicture
   SetWallPaper(LoadBitmap(Starter.daPaf, Starter.aWallPicX.Get(Starter.gtum))) ' change wallpaper
'CallSubDelayed(Main, "changePicture")
End Sub

What is a correct way to prevent a Transparent app from blocking access to the Device Screen icons, while keeping the app running?
Or what different way to solve this?
Thanks in advance.

What do you need the transparent activity for? The activity will consume the touch events.

The app covered the screen, I gave app a transparent background and could see the wallpaper changing. I was happy till I realized I couldn't click other stuff.
I'm taking this one step at a time for learning purposes, it sort of works but I can't get at the home screen.
I've tried minimizing the app but Main didn't Resume.

The last line of SetWallPaper:

tmrNoButn_Tick

Sub tmrNoButn_Tick
tmrNoButn.Enabled = True
Dim jo As JavaObject
jo.InitializeContext
jo.RunMethod("moveTaskToBack", Array(True))
tmrNoButn.Enabled = False
End Sub

Updates SetWallPaper in 1 second and hides my app, making the screen accessible.
Side note: Am wondering if this should be a widget, would the code from my Main run from a Service module?

it take less minutes to test it than to get an answer here. Try it

If you need to keep a window permanently, probably, there are reasons to use SYSTEM_ALERT_WINDOW and WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE flag.
Take a look https://www.b4x.com/android/forum/attachments/test-zip.72173/
I talk about approach only, Java code is too complex and specific to task here.

I should have written:
I added a timer routine and now it Updates SetWallPaper in 1 second and hides my app, making the screen accessible.
Now I'm working on the same issue each time Main does a Resume for its 2 hour wallpaper change (I don't want to use a 2 hour timer).

use a service. Change the wallpaper when the service starts.
After you have set it cal StartServiceAt in the service to reshedule it. 2 Hours interval should be OK for Android not to kill your app.
No need to resume your app every 2 hours
