Check network state in libGDX

Question

I would like to check Wifi stat in a libGDX project, tried to use code below:

   Gdx.net.sendHttpRequest(HttpRequest httpRequest, HttpResponseListener httpResponseListener);

    HttpResponseListener httpResponseListener = new  httpResponseListener() {
        public void handleHttpResponse (HttpResponse httpResponse) {
            HttpStatus status = httpResponse.getStatus();
            if (status.getStatusCode() >= 200 && status.getStatusCode() < 300) {
                // it was successful
            } else {
                // do something else
            }
        }
    }

I added permissions:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

It says HttpResponseListener cannot resolved. How should I fix this?

Answer 1

// there is a small 'h' here, which is wrong ---v
HttpResponseListener httpResponseListener = new httpResponseListener() {
    public void handleHttpResponse (HttpResponse httpResponse) {
        HttpStatus status = httpResponse.getStatus();
        if (status.getStatusCode() >= 200 && status.getStatusCode() < 300) {
            // it was successful
        } else {
            // do something else
        }
    }
}

// here, you still have the parameter types
Gdx.net.sendHttpRequest(HttpRequest httpRequest, HttpResponseListener httpResponseListener);
// this is correct
Gdx.net.sendHttpRequest(httpRequest, httpResponseListener);

Besides this, this probably won't work. If there is no internet connection, you will not get a response from the server. You have to override HttpResponseListener.failed().
