If FirstTime Then   
        kvs.Initialize(File.DirDefaultExternal,"datastore")   
        manager.Initialize("manager", inappkey)
        manager.DebugLogging = True
    End If

The Android emulator is not very reliable. You should test features such as in app purchases on a real device.

In main activity create itself app is crashing.So I cant even open my app itself in emulator ,even if I dont want to test InApp

Try
 manager.Initialize(...)
 manager.DebugLogging = True
Catch
 Log("IAP not available")
End Try
