Detect network connection type on Android

Question

How do you detect the network connection type on Android?

Is it through ConnectivityManager.getActiveNetworkInfo().getType(), and is the answer limited

Answer 1

Detect the what type of network and getting the boolean value of isconnected or not use below snippet

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.telephony.TelephonyManager;
public class NetworkManagerUtils {

/**
 * Get the network info
 * @param context
 * @return
 */
public static NetworkInfo getNetworkInfo(Context context){
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    return cm.getActiveNetworkInfo();
}

/**
 * Check if there is any connectivity
 * @param context
 * @return
 */
public static boolean isConnected(Context context){
    NetworkInfo info = NetworkManagerUtils.getNetworkInfo(context);
    return (info != null && info.isConnected());
}

/**
 * Check if there is any connectivity to a Wifi network
 * @param context.
 * @param type
 * @return
 */
public static boolean isConnectedWifi(Context context){
    NetworkInfo info = NetworkManagerUtils.getNetworkInfo(context);
    return (info != null && info.isConnected() && info.getType() == ConnectivityManager.TYPE_WIFI);
}

/**
 * Check if there is any connectivity to a mobile network
 * @param context
 * @param type
 * @return
 */
public static boolean isConnectedMobile(Context context){
    NetworkInfo info = NetworkManagerUtils.getNetworkInfo(context);
    return (info != null && info.isConnected() && info.getType() == ConnectivityManager.TYPE_MOBILE);
}

/**
 * Check if there is fast connectivity
 * @param context
 * @return
 */
public static boolean isConnectedFast(Context context){
    NetworkInfo info = NetworkManagerUtils.getNetworkInfo(context);
    return (info != null && info.isConnected() && NetworkManagerUtils.isConnectionFast(info.getType(),info.getSubtype()));
}

/**
 * Check if the connection is fast
 * @param type
 * @param subType
 * @return
 */
public static boolean isConnectionFast(int type, int subType){
    if(type== ConnectivityManager.TYPE_WIFI){
        return true;
    }else if(type==ConnectivityManager.TYPE_MOBILE){
        switch(subType){
            case TelephonyManager.NETWORK_TYPE_1xRTT:

public static String getNetworkClass(Context context) {

                return "4G";
            default:
                return "?";
        }
    }
    return "?";
}
}

use this following the class pass the context you will the get network status like network type,fast network,etc.
