Not sure I understood your post, maybe are you looking for somewhat like jAWTrobot ?

You can handle those events with jGameViewHelper library: https://www.b4x.com/android/forum/threads/gameview-simple-sprites-engine.57950/#content

An example just using jReflection

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    Dim Obj As Reflector
    Obj.Target = MainForm.RootPane
    Obj.AddEventHandler2("RootPaneKeyEvent", "onKeyPressedProperty")
    MainForm.Show
    MainForm.RootPane.RequestFocus
End Sub

Sub RootPaneKeyEvent_Event(e As Event)
    ' bit hackish to get the code
    Dim theKey As String = e
    'Log(e)
    Log("key pressed "& theKey.SubString2(theKey.IndexOf(", code = ")+9,theKey.Length-1))
End Sub

Thank you, @Daestrum

thanx to all, i just had to requestfocus to the rootpanel of mainform

gameview would be the right choice since i want to make a game but because it is for the game competition where no game libs are allowed i will use jreflection

thanx guys!
