Get Network Info

We can get all network info by calling getAllNetworkInfo() method of ConnectivityManager object.



AndroidNetworkInfo.java

package com.exercise.AndroidNetworkInfo;

import java.util.ArrayList;
import java.util.List;

import android.app.ListActivity;
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class AndroidNetworkInfo extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ConnectivityManager connectivityManager 
      = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo[] networkInfo
      = connectivityManager.getAllNetworkInfo();
        
        List listNetworkInfo = new ArrayList();
        for(int i=0; i         listNetworkInfo.add(networkInfo[i].toString());
        }

        setListAdapter(new ArrayAdapter(this,
          android.R.layout.simple_list_item_1, 
          listNetworkInfo));
        getListView().setTextFilterEnabled(true);
    }
}

Modify AndroidManifest.xml to grant permission to access network state

      package="com.exercise.AndroidNetworkInfo"
      android:versionCode="1"
      android:versionName="1.0">
    

    
                          android:label="@string/app_name">
