I am using imagedownloader and a service using httpjob and saxparser.

Such errors can happen because of a modal dialog (or DoEvents call) in Activity_KeyPress or inside a menu event.

I had it with subs related to menu items on android 4+
Solved using callsubdelayed(...) from the menu sub to run the code for menu items:

'add menus...
Activity.AddMenuItem("Connect","MnBtconn")
...

Sub MnBtconn_click
    CallSubDelayed(Me,"SubMnBtconn")  
End Sub

Sub SubMnBtconn  
    'connect to a bt device, disconnet if already connected
    ...
End Sub

hope this help
Cheers
