How to ping a site from an Android activity and get a response?
I used isReachable but it didn't work and I used ConnectivityManager and getNetworkInfo; it actually only works for checking if I am connected to the internet ...
But the problem is I want to check if I can access the internet, so I want to ping the site to see if there is an answer.

For get method:
private void executeReq(URL urlObject) throws IOException{
HttpURLConnection conn = null;
conn = (HttpURLConnection) urlObject.openConnection();
conn.setReadTimeout(100000); //Milliseconds
conn.setConnectTimeout(150000); //Milliseconds
conn.setRequestMethod("GET");
conn.setDoInput(true);
// Start connect
conn.connect();
String response = convertStreamToString(conn.getInputStream());
Log.d("Response:", response);
}
You can call him with
try {
String parameters = ""; //
URL url = new URL("http://alefon.com" + parameters);
executeReq(url);
}
catch(Exception e){
//Error
}
To test your internet connection use:
private void checkInternetConnection() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
if (null == ni)
Toast.makeText(this, "no internet connection", Toast.LENGTH_LONG).show();
else {
Toast.makeText(this, "Internet Connect is detected .. check access to sire", Toast.LENGTH_LONG).show();
//Use the code above...
}
}

Use this. This works great 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");
}
