kotlin network change listener android

1. Create a BroadcastReceiver class that extends BroadcastReceiver.

2. In the BroadcastReceiver class, override the onReceive() method. This method will be called whenever there is a change in the network state.

3. Inside the onReceive() method, check if the intent action is equal to ConnectivityManager.CONNECTIVITY_ACTION. This action indicates a change in the network state.

4. If the action is equal to ConnectivityManager.CONNECTIVITY_ACTION, retrieve the network connection status using the getSystemService() method. Pass the CONNECTIVITY_SERVICE constant as the argument.

5. Cast the returned object to ConnectivityManager and assign it to a variable, e.g., connectivityManager.

6. Use the getActiveNetworkInfo() method of the connectivityManager variable to get the active network information. This method returns a NetworkInfo object.

7. Check if the NetworkInfo object is not null and is connected. You can use the isConnected() method of the NetworkInfo object to check the connection status.

8. If the NetworkInfo object is connected, you can perform actions such as displaying a message or updating UI elements accordingly.

That's it! By following these steps, you can create a network change listener in Kotlin for Android.
