BackgroundFetch.getInstance(context).configure(config, object : BackgroundFetch.Callback {
    override fun onFetch(taskId: String) {
        Log.d(TAG, "[BackgroundFetch] Event received: $taskId")
        // Perform your work here...
        BackgroundFetch.getInstance(context).finish(taskId)
    }
    override fun onTimeout(taskId: String) {
        Log.d(TAG, "[BackgroundFetch] TIMEOUT: $taskId")
        BackgroundFetch.getInstance(context).finish(taskId)
    }
})

Custom task

val task = BackgroundFetchConfig.Builder()
    .setTaskId("com.transistorsoft.customtask")
