What is alternative to ConnectivityManager.TYPE_WIFI deprecated in Android P API 28?

Question

ConnectivityManager.TYPE_WIFI is deprecated in Android P API 28. Also, NetworkInfo#getType and ConnectivityManager.TYPE_MOBILE's are also deprecated.

So, what are the alternatives for them? I understood that the we've to use the method from NetworkCapabilities class. However I'm not able to merge all the things in one place like how to do getType() in NetworkCapabilities class and how to add the WIFI and cellular data checks on it?

Please assist.

Answer 1

You can use below snippet to check if you have Wifi connection or Cellular:

ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
    Network network = connectivityManager.getActiveNetwork();
    NetworkCapabilities capabilities = connectivityManager.getNetworkCapabilities(network);
    return capabilities != null && (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) || capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR));
}

Use below method.. 19/06/2019

public boolean isconnectedToWifi(Context context) {
    ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    if (connectivityManager == null) {
        return false;
    }

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        Network network = connectivityManager.getActiveNetwork();
        NetworkCapabilities capabilities = connectivityManager.getNetworkCapabilities(network);
        if (capabilities == null) {
            return false;
        }
        return capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI);
    } else {
        NetworkInfo networkInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
        if (networkInfo == null) {
            return false;
        }
        return networkInfo.isConnected();
    }
}

ConnectivityManager.TYPE_WIFI is Deprecated. You should use NetworkCapabilities.

This replaces the old ConnectivityManager.TYPE_MOBILE method of network selection. Rather than indicate a need for Wi-Fi because an application needs high bandwidth and risk obsolescence when a new, fast network appears (like LTE), the application should specify it needs high bandwidth. Similarly if an application needs an unmetered network for a bulk transfer it can specify that rather than assuming all cellular based connections are metered and all Wi-Fi based connections are not.

Applications should instead use NetworkCapabilities.hasTransport(int) or requestNetwork(NetworkRequest, NetworkCallback) to request an appropriate network. for supported transports.

You can try this way

NetworkAgentInfo networkAgent;
int type = ConnectivityManager.TYPE_NONE;
if (networkAgent.networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {
     type = ConnectivityManager.TYPE_MOBILE;
} else if (networkAgent.networkCapabilities.hasTransport(
     NetworkCapabilities.TRANSPORT_WIFI)) {
     type = ConnectivityManager.TYPE_WIFI;
}
