Declaring BroadcastReceivers in the manifest is deprecated
As per the provided link in the teacher's notes, https://developer.android.com/training/monitoring-device-state/connectivity-monitoring.html#MonitorChanges declaring BroadcastReceivers in the manifest is deprecated from Android 7.0 and up. From what I gather, this is in an effort to lower battery consumption.
What I did to receive the broadcast instead was to register the broadcast receiver in MainActivity's onCreate method:
... super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); IntentFilter intentFilter = new IntentFilter("android.net.conn.CONNECTIVITY_CHANGE"); this.registerReceiver(new NetworkConnectionReceiver(), intentFilter); ...
Registering a Broadcast Receiver in code is what the next video after the coding challenge is about, and it is shown in which lifecycle methods it's best to un/register Broadcast Receivers (unlike what I did in my code above).

I noted some manifest-declared receivers work just fine when declared on the manifest e.g. android.intent.action.AIRPLANE_MODE.
However, these receivers have to be registered dynamically inside the code for them to work: *android.intent.action.SCREEN_ON *android.intent.action.SCREEN_OFF *android.intent.action.HEADSET_PLUG *android.intent.action.TIME_TICK *android.net.conn.CONNECTIVITY_CHANGE (ConnectivityManager.CONNECTIVITY_ACTION) *android.intent.action.CONFIGURATION_CHANGED
