Dim ctxt As JavaObject
ctxt.InitializeContext

Dim JO As JavaObject = ctxt.RunMethodJO("getWindow", Null)
JO = JO.RunMethodJO("getDecorView", Null)
JO = JO.RunMethodJO("getRootWindowInsets",Null)
JO = JO.RunMethodJO("getDisplayCutout",Null)

If JO.IsInitialized Then
    Log("Device has a notch")
    JO = JO.RunMethodJO("getSafeInsetTop",Null)
    Log("Notch Height: " & JO)
End If

I've tried this code but the "JO" always return 'Not initialized', tested both in emulator and phone with notch.

Note that this method is only available on Android 8+. The code is correct. If it is not initialized then the device doesn't have a notch or doesn't support this feature properly.
