In what situations is it recommended to use the BroadcastReceiver component in Android applications?

BroadcastReceiver in Android is recommended to be used in the following situations:

• To respond to system events, such as changes in network state, charging, device boot.
• To receive broadcast messages from other applications or components within the application.
• To initiate actions in response to events when the application is not active (e.g., receiving SMS).

It is important to note that from Android 8.0 (API 26), there are restrictions on static BroadcastReceivers, so dynamic registration in code is often used.

Example of dynamic registration:

BroadcastReceiver receiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        // handle event
    }
};
IntentFilter filter = new IntentFilter(Intent.ACTION_BATTERY_LOW);
context.registerReceiver(receiver, filter);
