The format of realm object storage makes it really straightforward to store the nested data that makes up a route. The routes are all stored locally with a Realm database. Once a connection is established, functions of the service can be accessed through the connection.ĮventBus is also used to allow the service to notify the app when important things happen that may require UI to be updated. The app can't directly access the running service like a normal static instance or class, a connection must be made using a Service Binding. It checks the intent's extras for keys and performs the corresponding action. When a user taps on a button on the foreground service notification, the service receives an intent. ![]() The foreground service is controlled in two ways: Android Intents The interface is pretty simple, you feed it a configuration, start the location request, and then handle the location updates as they roll in. Internally the LocationRecorderService utilizes the FusedLocationProvider library from google. This requirement works perfectly for this app because it allows us to provide the user with route recording actions such as pausing/stopping/adding a waypoint without needing to open the app. The main requirement of a foreground service is that you must display a notification as long as it's running. The nice thing about using foreground services is that it's much less likely to be killed by over-zealous system optimization initiatives. ![]() To record location in the background, the app uses a foreground service class, LocationRecorderService.
