  1. iDrive Mid-term project review

  2. Team Objectives • Retrieve the route from the routing engines at regular intervals • Manipulate the in-built phone GPS such that it will send programmer defined GPS co-ordinates to the OSMAND application • Faking the GPS will enable the application to be tested in any part of the world

  3. Approach • Get the route from the route engine (GPX file) and display the route on the screen • Store the co-ordinates from the GPX file into an ArrayList (done in the code) • Override the app code to provide new lat, long values wherever onLocationChanged (Location location) is called • Replace Location.getLatitude() with mock_res.get(count).getLatitude() and similarly for longitude • Built a timer to increment the count and provide new location on requestLocationUpdate() • Getting built without errors

  4. Route • Screenshot of the route being displayed

  5. Justification • There were three options for implementation: • Changing the framework • Changing the app code • Difficult to implement. Changes in one section of the code may cause problems in other sections. • Using the Eclipse Emulator • The phone would not be able to be tested for performance meaaures

  6. Modified Approach • Add code to framework to pass the array entries to the public abstract void onLocationChanged (Location location) • Each time onLocationChanged is called, it should be passed a new set of co-ordinates from the ArrayList • After a set time interval, the OSMAND code should send the current location of the device to the route engine and retrieve a new route

  7. Flow OSMAND application Route Engine Get Route Store coordinates Send Location onLocationChanged Android Framework Pass fake co-ordinates to onLocationChanged

  8. Obstacles • Understanding the android code • According to the initial approach, it was tough to identify the parts of code that would need modifications • Compile and edit framework • Testing (wireless signal …)

  9. Schedule • Tasks • Displaying the route • Modifying the android framework to fake the GPS readings • Implementing a timer function to call the route engine at regular intervals and refreshing the route • Add current location to UI • Finish by Mid-November
