[FIXED] How can I check internet connection in Android Q?

Issue

Before Android Q all you had to do is use the NetworkUtils class. But this class was deprecated in API 29. I've been searching for an alternative, and I couldn't seem to find one.

So, how can I check the internet connection in Android Q?

Solution

Use this code snippet.

     @IntRange(from = 0, to = 3)
public static int getConnectionType(Context context) {
    int result = 0; // Returns connection type. 0: none; 1: mobile data; 2: wifi
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (cm != null) {
            NetworkCapabilities capabilities = cm.getNetworkCapabilities(cm.getActiveNetwork());
            if (capabilities != null) {
                if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
                    result = 2;
                } else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {
                    result = 1;
                } else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_VPN)) {
                    result = 3;
                }
            }
        }
    } else {
        if (cm != null) {
            NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
            if (activeNetwork != null) {
                // connected to the internet
                if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
                    result = 2;
                } else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
                    result = 1;
                } else if (activeNetwork.getType() == ConnectivityManager.TYPE_VPN) {
                    result = 3;
                }
            }
        }
    }
    return result;
}

Happy Coding :)
