1. Run the ContextMiddleware, first.
2. Run the SampleForegroundApplication, next.

If you are using an emulator, you have to set the location explicitly for the middleware to understand that a change in location has taken place. You can either use the extended settings for the emulator or connect to the emulator using telnet.

It is not possible to simulate the headphone jack being connected or disconnected feature using the emulator. To test that functionality, use a physical device. Remember to enable USB debugging when using a physical device.

1. Once the application starts running and the service is connected, click on the "Get Location" button.
2. Change your location in settings (give random coordinates) or use a mock location app on the physical device.

Whenever the location is changed, the application will show the new coordinates.

1. Set a random location as specified in the "Get Location" functionality above.
2. Click on the "Notify at NewYork" button. This sets flag in the service to invoke the application when the user is detected to be in New York City
3. Change your location in settings (give random coordinates) or use a mock location app on the physical device to somewhere close to (or same as) the following coordinates: [latitude = 40.7128; longitude = -74.0059]

1. Run the middleware, and then the application on a physical device.
2. Click on the "Check Headset Status" button.

A message will be shown whether the headphones are connected or not.
