The AIR API, under the hood, uses the Android LocationManager class to receive location and accuracy information. It also receives additional information about satellites and fixes, but it doesn’t expose this information at the time of this writing.
On Android, if you want to simulate geolocation coordinates, select Settings→Applications→ Development→Mock locations. This is a setting you could choose if you are using the emulator to simulate an itinerary without actually being there. As the time of this writing, it is not supported in AIR for Android:
<uses-permission android:name=”android.permission.ACCESS_MOCK_LOCATION” />
