Boblim Android中判断网络连接是否可用及监控网络状态 https://www.cnblogs.com/fnlingnzb-learner/p/7531811.html
LAN/WAN/WLAN/WWAN区别总结 https://blog.csdn.net/wenlong199/article/details/104521107
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"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.gatsby.networktest" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="22" android:targetSdkVersion="22" /> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name=".MyBroadcast" > <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <action android:name="android.net.wifi.STATE_CHANGE" /> <action android:name="android.Net.wifi.WIFI_STATE_CHANGED" /> <!-- 网络更改广播 --> <action android:name="android.net.conn.CONNECTIVITY_CHANGE" /> </intent-filter> </receiver> <service android:name=".NetworkService" > </service> </application> </manifest>
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:

Intent wifiIntent = new Intent();
wifiIntent.setAction("com.xinhua.wifiIntent");
context.sendBroadcast(wifiIntent);
break;
case 0:

break;
default:
break;
}
}
}
private int isNetworkAvailable(Context mcontext) {

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;
}
