I am trying to write a part in my app that will differentiate between an Active Wifi connection and an actual connection to the internet. Finding out if there is an active
You can do it by create new parallel thread
that count time :
final class QueryClass {
private int responseCode = -1;
private String makeHttpRequest(URL url) throws IOException {
String jsonResponse = "";
if(url == null) {
return null;
}
HttpURLConnection urlConnection = null;
InputStream inputStream = null;
try {
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setReadTimeout(5000 );
urlConnection.setConnectTimeout(5000 );
Thread thread = new Thread() {
@Override
public void run() {
super.run();
try {
sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
if(responseCode == -1) {
//Perform error message
Intent intent = new Intent(context,ErrorsActivity.class);
intent.putExtra("errorTextMessage",R.string.errorNoInternet);
intent.putExtra("errorImage",R.drawable.no_wifi);
context.startActivity(intent);
}
}
};
thread.start();
urlConnection.connect();
responseCode = urlConnection.getResponseCode();
if (responseCode == 200) {
inputStream = urlConnection.getInputStream();
jsonResponse = readFromStream(inputStream);
}
