NetworkInfo depretricated

The NetworkInfo class in Android has been deprecated since API level 29. This means that it is no longer recommended to use this class for network connectivity checks in your Android applications. In this guide, we will explore the deprecation, understand the reasons behind it, and learn about the alternative approaches.

Deprecation Reason

The deprecation of NetworkInfo is a result of the introduction of a more modern and reliable connectivity management system in Android. With the release of Android 10 (API level 29) and above, the Android team introduced the NetworkCapabilities and ConnectivityManager.NetworkCallback classes to handle network connectivity.

Alternative Approaches

1. Using NetworkCapabilities

You can use the NetworkCapabilities class to check for network capabilities such as Internet connectivity, bandwidth, and transport type.

ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkCapabilities networkCapabilities = connectivityManager.getNetworkCapabilities(connectivityManager.getActiveNetwork());

boolean isConnected = networkCapabilities != null && networkCapabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);

2. Registering NetworkCallback

To receive notifications about network changes, you can register a NetworkCallback with the ConnectivityManager.

ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
ConnectivityManager.NetworkCallback networkCallback = new ConnectivityManager.NetworkCallback() {
    @Override
    public void onAvailable(Network network) {
        // network available
    }

    @Override
    public void onLost(Network network) {
        // network lost
    }
};

connectivityManager.registerDefaultNetworkCallback(networkCallback);
Migration Steps

Here are the steps to migrate from using NetworkInfo to the recommended approaches:

  1. Remove any code that uses NetworkInfo class.
  2. Replace network connectivity checks with NetworkCapabilities as shown in the first approach.
  3. Replace network change listeners with NetworkCallback registration as shown in the second approach.
Summary

In conclusion, the NetworkInfo class has been deprecated and replaced with more modern and reliable approaches like NetworkCapabilities and NetworkCallback. It is essential to update your code to utilize these new classes for handling network connectivity in Android applications.

Remember to update your code and migrate to the recommended approaches to ensure compatibility with the latest Android versions and provide a better user experience.
