I would like an application that on an Android phone, can record the following events;

1- The GPS, LAT and LON locations.
2- The Call events, (i.e. call made, call terminated, call dropped, handover).
3- The Layer-2 and Layer-3 signalling.
4- Other messages which are part of the call events, such as the Handover, Signal strength, the neighbours signal strength, Location Update, etc.

It would also be good to show some of this on the phone screen.

Download the map on the screen from Google or bingmaps.

Have a seprate file, that can import certain other layers, such as cell sites, POI, etc.

Thanks.
