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.

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();
}


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.



hopes that helps

    You need to move the call off your main thread. Android 4 enforces no network calls on the main thread to prevent ANR issues.

    This will establish a TCP connection with a full 3-way handshake. So the time is nothing like a ping (ICMP-echo -> ICMP-reply)
