Answer 1

use following code:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import classes.NetworkUtil;

public class NetworkChangeReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(final Context context, final Intent intent) {

            boolean IsConnected = NetworkUtil.getConnectivityStatusString(context);
           // Toast in here, you can retrieve other value like String from NetworkUtil
           // but you need some change in NetworkUtil Class
        }
    }

and NetworkUtil is:

package classes;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;

public class NetworkUtil {

    public static int TYPE_WIFI = 1;
    public static int TYPE_MOBILE = 2;
    public static int TYPE_NOT_CONNECTED = 0;


    public static int getConnectivityStatus(Context context) {
        ConnectivityManager cm = (ConnectivityManager) context
                .getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
        if (null != activeNetwork) {
            if(activeNetwork.getType() == ConnectivityManager.TYPE_WIFI)
                return TYPE_WIFI;

            if(activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE)
                return TYPE_MOBILE;
        } 
        return TYPE_NOT_CONNECTED;
    }

    public static boolean getConnectivityStatusString(Context context) {
        int conn = NetworkUtil.getConnectivityStatus(context);
        boolean status = false ;
        if (conn == NetworkUtil.TYPE_WIFI) {
            status = true;
        } else if (conn == NetworkUtil.TYPE_MOBILE) {
            status = true; 
        } else if (conn == NetworkUtil.TYPE_NOT_CONNECTED) {
            status = false;
        }
        return status;
    }
}

and in manifest file:
