Android getAllNetworkInfo() is Deprecated. What is the alternative?

Question

I want to use the ConnectivityManager which provides the getAllNetworkInfo() method for checking the availability of network in Android. This method wa

Answer 1

I've made utils that may help you to check:

• If network is connected.
• If WiFi is connected.
• If mobile data is connected.

it uses old or new API depending on running platform :

import android.annotation.TargetApi;
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.Network;
import android.net.NetworkInfo;
import android.os.Build;
import android.support.annotation.NonNull;

public class NetworkUtils {

    public static boolean isConnected(@NonNull Context context) {
        ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
        return (networkInfo != null && networkInfo.isConnected());
    }

    public static boolean isWifiConnected(@NonNull Context context) {
        return isConnected(context, ConnectivityManager.TYPE_WIFI);
    }

    public static boolean isMobileConnected(@NonNull Context context) {
        return isConnected(context, ConnectivityManager.TYPE_MOBILE);
    }

    private static boolean isConnected(@NonNull Context context, int type) {
        ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            NetworkInfo networkInfo = connMgr.getNetworkInfo(type);
            return networkInfo != null && networkInfo.isConnected();
        } else {
            return isConnected(connMgr, type);
        }
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    private static boolean isConnected(@NonNull ConnectivityManager connMgr, int type) {
        Network[] networks = connMgr.getAllNetworks();
        NetworkInfo networkInfo;
        for (Network mNetwork : networks) {
            networkInfo = connMgr.getNetworkInfo(mNetwork);
            if (networkInfo != null && networkInfo.getType() == type && networkInfo.isConnected()) {
                return true;
            }
        }
        return false;
    }

}
