Android Flurry events are not reported on the dashboard

I have integrated Flurry in a test project. I am trying to send events to Flurry but they are not reported at all on the Flurry dashboard. I have followed carefully how to integrate it in my app:

@Override
protected void onStart()
{
    super.onStart();
    FlurryAgent.onStartSession(this, "XXXXXXXXXXXXX");
}

@Override
protected void onStop()
{
    super.onStop();     
    FlurryAgent.onEndSession(this);
}

public void sendEvent(View view){
    FlurryAgent.logEvent("Page_Viewed");
}

The log of the device is:

12-06 10:46:53.692: W/FlurryAgent(2058): Start session
12-06 10:46:54.232: W/FlurryAgent(2058): FlurryDataSender: report eb66f44c-1a59-4b5d-82df-04a9bf5a086a sent. HTTP response: 200 : OK
12-06 10:47:00.972: W/FlurryAgent(2058): Event count started: Article_Read

I stop the app and I restart it:

12-06 10:47:18.302: W/FlurryAgent(2058): Trying to end session
12-06 10:47:28.313: W/FlurryAgent(2058): Ending session
12-06 10:47:33.193: W/FlurryAgent(2058): Start session

I have waited more than 48 hours and I still do not see anything on the dashboard. I am using the Flurry SDK version 3.3.1.
