Android HTC Sense - Http Request/ Response exception

Question

Working on the emulator, but when I am trying on an HTC Sense, i have got an exception on the last line of this code

url = new URL(urlString);
connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", 
                "application/json; charset=utf-8");

//Send request
Gson requestGson = new Gson();          
OutputStream wr = connection.getOutputStream();

The exception is java.net.ProtocolException: Does not support output for the connection.getOutputStream();

I am testing on API 10, Gingerbread on an HTC Sense (remote debugging).

anyone has encountered this problem before?

Thanks. David.

Are you still having [this problem](http://stackoverflow.com/questions/12962645/noclassdeffounderror-on-htc-sense)? Or is that part of this question? Or...? — Cat, Oct 18 '12 at 20:39

Try calling setDoOutput(true). It is needed for POST requests. The first part of your code would change to look like this:

connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", 
            "application/json; charset=utf-8");
connection.setDoOutput(true);
