Sample Notification

The example below shows how to create a notification that can be passed to SentianceOptions. We use the class to build a notification suitable for both old and recent Android versions.

The notification channel, necessary for Android 8 and above, has the channel importance set to IMPORTANCE_LOW, the minimum recommended by Google for notifications used for running services.

private fun createNotification(): Notification {
    // PendingIntent that will start your application's MainActivity
    val intent = Intent(context,
    val pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_IMMUTABLE)

    // On Oreo and above, you must create a notification channel
    val channelId = "background_detections"
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val channel = NotificationChannel(channelId, "Background Detections", NotificationManager.IMPORTANCE_LOW)
        val notificationManager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    return Builder(context, channelId)
        .setContentTitle(context.getString(R.string.app_name).toString() + " is running")
        .setContentText("Touch to open.")

You can quickly test the notification appearance by running a fresh app/SDK installation on an Android 8+ device. The notification will appear the first time the SDK starts automatic detections, or when you manually start a trip (more about this here).
