Android 获取联网方式及代理联网
?
?
public final static String NetType(Context context) {
try {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = cm.getActiveNetworkInfo();
String typeName = info.getTypeName().toLowerCase(); // WIFI/MOBILE
if (typeName.equals("wifi")) {
} else {
typeName = info.getExtraInfo().toLowerCase();
// 3gnet/3gwap/uninet/uniwap/cmnet/cmwap/ctnet/ctwap
}
return typeName;
} catch (Exception e) {
return null;
}
}
没有网络时会出现异常，位置为ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);?
NetworkInfo info = cm.getActiveNetworkInfo();
使用代理联网时得到连接对象的方法
?
public final static HttpURLConnection getURLConnection(String url) throws Exception {
String proxyHost = android.net.Proxy.getDefaultHost();
if (proxyHost != null) {
java.net.Proxy p = new java.net.Proxy(java.net.Proxy.Type.HTTP, new InetSocketAddress(android.net.Proxy.getDefaultHost(),
android.net.Proxy.getDefaultPort()));
return (HttpURLConnection) new URL(url).openConnection(p);
} else {
return (HttpURLConnection) new URL(url).openConnection();
}
}
返回HttpURLConnection对象android.net.Proxy.getDefaultHost()得到手机设置的代理ip，得到android.net.Proxy.getDefaultPort()得到手机设置的端口；?
也可以自己设置为 10.0.0.172 端口 80
