Android : geozones pushwoosh in Android

I have implemented pushwoosh in my Android app. I have not been able to get automatic Geozone notifications.

In the Log of Eclipse I can see the LocationUpdateService that works and update the position , in fact, if I try to manually send a notification to the devices that are located in that area , it's all ok , but automatic notifications of Geozones "that allow sending automatically triggered push notifications right at the moment a user enters the specified area on the map" don't work when I enter in a geozone.

I add this code in my activity:

pushManager.startTrackingGeoPushes();

and in the manifest:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<service android:name="com.arellomobile.android.push.GeoLocationService"/>

Has anyone tested the automatic features of geozones? Where is the problem that I do not get these notifications?
