如何来ping从Android的活动网站，并得到回应？ [英] How to ping a website from an Android activity and get response?

问题描述

我用isReachable，但它没有工作，我用ConnectivityManager和getNetworkInfo;其实这只能检查如果我连接到互联网...

I used isReachable, but it didn't work, and I used ConnectivityManager and getNetworkInfo; actually this works only to check if I am connected to the Internet...

但问题是我要检查，如果我能上网的，所以我想用ping一个网站，以检查是否有响应。

But the issue is I want to check if I can access the Internet so I want to ping a website to check if there is a response.

推荐答案

使用这一个.. 这正常工作对我来说：）

Use this one.. This works fine for me :)

public static void isNetworkAvailable(Context context){
    HttpGet httpGet = new HttpGet("http://www.google.com");
    HttpParams httpParameters = new BasicHttpParams();
    // Set the timeout in milliseconds until a connection is established.
    // The default value is zero, that means the timeout is not used.
    int timeoutConnection = 3000;
    HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
    // Set the default socket timeout (SO_TIMEOUT)
    // in milliseconds which is the timeout for waiting for data.
    int timeoutSocket = 5000;
    HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

    DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
    try{
        Log.e("checking", "Checking network connection...");
        httpClient.execute(httpGet);
        Log.e("checking", "Connection OK");
        return;
    }
    catch(ClientProtocolException e){
        e.printStackTrace();
    }
    catch(IOException e){
        e.printStackTrace();
    }

    Log.e("checking", "Connection unavailable");
}
