Our approach is to treat all of these factors the same. Testing and development all provide locations through the same interfaces as the "normal" devices. The LocationManager represents physical location providing instruments with two different object types; LocationDevice and LocationProvider. The LocationDevice class describes the instrument, but doesn't interact with it, and can be thought of as a "File Descriptor". A LocationProvider will consume the data stream from the location instrument, and actually provide the Location updates to the application (mediated by the LocationFramework). |
| The Application generally does not interact directly with the LocationProvider in use. Rather the Application will do most of the work using the LocationManager. The AGTEK LocationManager is retrieved using a Singleton pattern instead of using an Android OS interface; | The Application generally does not interact directly with the LocationProvider in use.

| Applications may playback the location stream using the PlaybackDevice/PlaybackProvider. These function exactly the same as a normal LocationManager capable instrument. The PlaybackProvider will send updates back to the application at exactly the same rate as they were recorded. | Applications may playback the location stream using the PlaybackDevice/PlaybackProvider.

| + | The LocationManager is still relatively early in its development, so changes are to be expected. In particular areas of device initialization/startup and reporting status to applications are not well developed. These are expected to mature as new devices are added to the framework. | ||
