GPS based vehicle tracking app - 2

The following features should be available. 1) Menu to login/logout, FAQ, contact us. 2) Login menu for first time login only. After logged in once, the session should be preserved always until logged out explicitly by user. 3) Get the list of vehicle from the server immediately after login. 4) Show the vehicle list in a menu from bottom (only the 1st vehicle name will be displayed by default here). The bottom menu containing the vehicle list could be pulled up to see/select the remaining vehicle. 5) Get the vehicle's current position (latitute, longitude, speed & time) using php post from the server. Mark the location received on google map. This has to be done every time a new vehicle is selected. 6) Periodically (every 5 seconds) receive the new vehicle position and update the information on the map. 7) Status of vehicle (stationary/speed) and last received time should always shown in a status bar apart from the map.
