Android Volley - Verificando o estado da Internet
Antes de usar o Volley, como sempre, usei o AsyncTask para verificar meu estado da Internet.
Aqui está o que eu fiz no AsyncTask:
private class NetCheck extends AsyncTask<String, Void, Boolean> {
@Override
protected Boolean doInBackground(String... args) {
// get Internet status
return cd.isConnectingToInternet();
}
protected void onPostExecute(Boolean th) {
if (th == true) {
new LoadCategories().execute();
} else {
Toast.makeText(CategoryActivity.this, "Unable to connect to server",
Toast.LENGTH_LONG).show();
}
}
}
E isso éisConnectingToInternet
função:
public boolean isConnectingToInternet() {
ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity != null) {
NetworkInfo info = connectivity.getActiveNetworkInfo();
if (info != null && info.isConnected())
try {
URL url = new URL("http://www.google.com");
HttpURLConnection urlc = (HttpURLConnection) url
.openConnection();
urlc.setConnectTimeout(3000);
urlc.connect();
if (urlc.getResponseCode() == 200) {
return true;
}
} catch (MalformedURLException e1) {
e1.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return false;
}
Como faço para isso usando o Volley?
