I would like to equip the users to query the location of the taxi through my app. Lets say the User clicks on a button to know the nearest location of a taxi which is equipped with an android powered GPS device, the user should be given the location of that nearest taxi on his map. To be precise, i would like to track the location and if possible the movement of another GPS enabled device from the user's phone. I am using google maps API to display the map and markers. Now my question is Would it be possible to track another device through the android API, with the consent of the owner of the device?

It is sort of a service to track local taxi network around my place. I am working on building an application that tracks a GPS enabled android device.
