APK：ethernet广播监听以太网状态、ping外网、广播监听wifi的状态

 一.LAN/WAN/WLAN/WWAN区别总结

LAN: Local Area Network : 局域网
WAN: Wide Area Network, 广域网
WLAN: Wireless LAN, 无线局域网
WWAN: Wireless WAN: 无线广域网

二.以太网监听广播

2.1.AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>


    

    
    
    
    
    
    

    
        
            
                

                
            
        

        
            
                
                
                
                
                
            
        

        
        
    

　　

2.2.MyBroadcast.java

package com.gatsby.networktest;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.util.Log;

public class MyBroadcast extends BroadcastReceiver {

	static final String BOOT_COMPLETED = "android.intent.action.BOOT_COMPLETED";
	public int NET_ETHERNET = 1;
	public int NET_WIFI = 2;
	public int NET_NOCONNECT = 0;

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub

		String action = intent.getAction();

		if (action.equals(BOOT_COMPLETED)) {
			Intent startService = new Intent(context, NetworkService.class);
			Log.d("gatsby", "BOOT_COMPLETED Broadcast-----------!!!!");
			context.startService(startService);
		} else if (action.equals(ConnectivityManager.CONNECTIVITY_ACTION)
				|| action.equals("android.net.conn.CONNECTIVITY_CHANGE")) {

			switch (isNetworkAvailable(context)) {
			case 1:
				Log.d("gatsby", "-----------networktest---------ethernetState");
				Intent etherIntent = new Intent();
				etherIntent.setAction("com.xinhua.etherIntent");
				context.sendBroadcast(etherIntent);

				break;
			case 2:
				Log.d("gatsby", "-----------networktest---------wifinetState");
				Intent wifiIntent = new Intent();
				wifiIntent.setAction("com.xinhua.wifiIntent");
				context.sendBroadcast(wifiIntent);
				break;
			case 0:
				Log.d("gatsby", "-----------networktest---------NONO");

				break;
			default:
				break;
			}
		}

	}

	private int isNetworkAvailable(Context mcontext) {
		ConnectivityManager connectMgr = (ConnectivityManager) mcontext.getSystemService(Context.CONNECTIVITY_SERVICE);
		NetworkInfo ethNetInfo = connectMgr.getNetworkInfo(ConnectivityManager.TYPE_ETHERNET);
		NetworkInfo wifiNetInfo = connectMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

		if (ethNetInfo != null && ethNetInfo.isConnected()) {
			return NET_ETHERNET;
		} else if (wifiNetInfo != null && wifiNetInfo.isConnected()) {
			return NET_WIFI;
		} else {
			return NET_NOCONNECT;
		}
	}

}

 三.节点判断以太网插拔状态   cat /sys/class/net/eth0/carrier

四.ping 外网 　

	public static final boolean ping() {

		String result = null;
		try {
			String ip = "www.baidu.com";
			Process p = Runtime.getRuntime().exec("ping -c 3 -w 100 " + ip);
			int status = p.waitFor();
			if (status == 0) {
				result = "success";
				return true;
			} else {
				result = "failed";
			}
		} catch (IOException e) {
			result = "IOException";
		} catch (InterruptedException e) {
			result = "InterruptedException";
		} finally {
			Log.d("gatsby", " ping result = " + result);
		}
		return false;
	}

 五.wifi网卡状态、操作网卡的权限

5.1.wifi网卡状态
a.WIFI_STATE_DISABLED:WIFI网卡不可用
b.WIFI_STATE_DISABLING:WIFI正在关闭
c.WIFI_STATE_ENABLED:WIFI网卡可用
d.WIFI_STATE_ENABLING:WIFI网卡正在打开
e.WIFI_STATE_UNKNOWN:未知网卡状态
