Android Trip Detection
======================


The SDK can detect vehicle movements and notify your app when a trip is detected. 

**NB: At the moment, only bicycle or car trips can be detected.**

Before enabling trip detection, SafeRider must be initialized and the application needs to have been granted the **ACTIVITY_RECOGNITION** permission.

In order to be notified about trip detection events, you have to set a :code:`LRTripDetectionListener` in your application’s :code:`onCreate()`.

Then to start listening to user movements call :code:`enableTripDetection()`.

.. code-block:: kotlin

	class TestApplication : Application() {
	   private val demoTripListener = object : LRTripDetectionListener {
	       override fun onTripDetected(vehicleType: LRVehicleType) {
	           Log.d(TAG, "onTripDetected: $vehicleType")
	       }
	   }

	   override fun onCreate() {
	       super.onCreate()
	       SafeRider.initialize(
	           context = applicationContext,
	           apiKey = "apiKey",
	       )
	       // The trip listener should be set right after init.
	       SafeRider.sharedInstance.tripListener = demoTripListener
	       SafeRider.sharedInstance.enableTripDetection(LRVehicleType.BICYCLE)
	   }
	}
