TapGestureRecognizer not firing for Android

TapGestureRecognizer is working for WinPhone but on Android although the Application Output is showing [ViewRootImpl] ViewPostImeInputStage ACTION_DOWN but the Tapped evenit isn't being called...

        var listGestureRecognizer = new TapGestureRecognizer();
        listGestureRecognizer.Tapped += (s, e) =>
        {
    //do something...
        };
        listArea.GestureRecognizers.Add(listGestureRecognizer);

Any suggestions...
