url.openConnection() does not open the connection to the server - android

I'm going to use HttpUrlConnection for calling a WebAPI. I simply call url.OpenConnectionMethod() to open the connection, but it doesn't work. Both allowUserInteraction and client.connected values of HtpUrlConnection instance are false.
URL url = new URL("http://myserver/service/api/ads/getads");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
any help would be appreciated.


Try this:
URL url = new URL("http://yourserver/x/y/z");
URLConnection urlConnection = url.openConnection();
if this doesn't work can I see any exceptions?

HttpURLConnection not allowing me to post when I have https:// in the URL

How can I get POST request to work with an "https:" url?
In the following example when I set the URL to "https" instead of "http" the HttpURLConnection automatically makes my request a "GET" ?! while when it was a regular http request it was a POST...
URL url = new URL("*https:*//www.google.com");
// URL url = new URL("*http:*//www.google.com");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
urlConnection.setDoOutput(true);
urlConnection.setChunkedStreamingMode(0);
OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
//writeStream(out);
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
// readStream(in);
}finally {
urlConnection.disconnect();
}

Use HttpsURLConnection instead of HttpURLConnection

Http connection getInputStream null pointer exception android

I'm getting null pointer exception on method getInputStream() and I know that urlConnection isn't null
URL url = new URL(strUrl);
/** Creating an http connection to communcate with url */
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
/** Connecting to url */
urlConnection.connect();
/** Reading data from url */
iStream = urlConnection.getInputStream();
Url string is fine I'm checking it in my browser.
Thank you.

android urlconnection forces ssl

I am trying to connect to a server on port 8080 but AndroidHttpClient is forcing everything not on 8080 to use SSL. The offending code
URL url = new URL("http", "google.com", 8080, "");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setRequestProperty("Accept", "*/*");
urlConnection.connect();
and this from Charles log.
note the URL field is using "https://"
now when I change the port to 80:
URL url = new URL("http", "google.com", 80, "");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setRequestProperty("Accept", "*/*");
urlConnection.connect();
everything works fine:
I have no idea why it forces it to SSL when not on port 80. I had a similar issue with AndroidHttClient as well as DefaultHttpClient. Seems to be an issue with Android.

You can use HttpUrlConnection in android.
