How to Ping a Url in an Android Service

How to ping a URL in an Android Service?

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); // Timeout 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.

android ping a URL (not to open)

HttpURLConnection connection = null;
    try {
        URL u = new URL("http://www.google.com/");
        connection = (HttpURLConnection) u.openConnection();
        connection.setRequestMethod("HEAD");
        int code = connection.getResponseCode();
        System.out.println("" + code);
        // You can determine on HTTP return code received. 200 is success.
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } finally {
        if (connection != null) {
            connection.disconnect();
        }
    }

Android - Check internet connection by pinging url address

try this create a class that extends AsyncTask

public class CheckInternet extends AsyncTask<Void, Void, Boolean>{
 private static final String TAG = "CheckInternet";
private Context context;

public CheckInternet(Context context) {
    this.context = context;

}

@Override
protected Boolean doInBackground(Void... voids) {
    Log.d(TAG, "doInBackground: ");
    ConnectivityManager cm =
            (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

    assert cm != null;
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean isConnected = activeNetwork != null &&
            activeNetwork.isConnected();

    if (isConnected) {
        if ( executeCommand()) return true;
    }
    return false;
}

private boolean executeCommand(){
    System.out.println("executeCommand");
    Runtime runtime = Runtime.getRuntime();
    try
    {
        Process  mIpAddrProcess = runtime.exec("/system/bin/ping -c "+"www.google.com");
        int mExitValue = mIpAddrProcess.waitFor();
        System.out.println(" mExitValue "+mExitValue);
        if(mExitValue==0){
            return true;
        }else{
            return false;
        }
    }
    catch (InterruptedException ignore)
    {
        ignore.printStackTrace();
        System.out.println(" Exception:"+ignore);
    }
    catch (IOException e)
    {
        e.printStackTrace();
        System.out.println(" Exception:"+e);
    }
    return false;
}
