How can I use Android Service to do a ping callback? I need to open a webpage on a button click, but in the background, go ping another URL for stats collection.

推荐答案

我认为，如果您只想ping通URL，则可以使用以下代码:

I think if you just want to ping an url, you can use this code :

try {
    URL url = new URL("http://"+params[0]);

    HttpURLConnection urlc = (HttpURLConnection) url.openConnection();
    urlc.setRequestProperty("User-Agent", "Android Application:"+Z.APP_VERSION);
    urlc.setRequestProperty("Connection", "close");
    urlc.setConnectTimeout(1000 * 30); // mTimeout is in seconds
    urlc.connect();

    if (urlc.getResponseCode() == 200) {
        Main.Log("getResponseCode == 200");
        return new Boolean(true);
    }
} catch (MalformedURLException e1) {
    e1.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

并且，如果您希望获得与ping相同的效果，则可以在调用之前和之后放置System.currentTimeMillis()并计算差值.

And, if you want to have the equivalent of a ping, you can put a System.currentTimeMillis() before and after the call, and calculate the difference.
