Description from the creator

By default, a BroadcastReceiver is only active as long as it's onReceive method runs. Once this method returns, the containing app process only becomes as important as the other components that it contains. If we don't have an activity or foreground service running, our app is considered a background process and can be killed if the system needs memory.
This becomes a problem if we start a background thread in onReceive to handle long-running operations off the UI thread, because when the process gets killed, the started thread will be terminated together with it, which can lead to unexpected behavior.
In this video, we will learn how we can use the goAsync method to tell the system that it should keep our BroadcastReceiver active for a bit longer after onReceive finished.
GoAsync returns a PendingResult which is particularly useful if we want to use our long-running receiver in combination with an ordered broadcast.
