HttpPost give IO error

Hi all,

I just started with Android today and I try to get information from a site based on an available API. I tried the URL in a browser and it is correct, but when I try to connect with a HttpPost it fails on a IOException on the line: "this.response = client.execute(post);"

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

@Override
 
        public void onCreate(Bundle savedInstanceState) {
 
                super.onCreate(savedInstanceState);
 
                // Create a http connection
 
                HttpClient client = new DefaultHttpClient();
 
                HttpPost post = new HttpPost(URL_ROOT + CHARACTER_SHEET);
 
                try {
 
                        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
 
                        // Your DATA
 
                        nameValuePairs.add(new BasicNameValuePair("userId", USER_ID));
 
                        nameValuePairs.add(new BasicNameValuePair("apiKey", API_KEY));
 
                        post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
 
                        this.response = client.execute(post);
 
                        ConnectionEventHandler responseEvent = new ConnectionEventHandler(
 
                                        this);
 
                } catch (ClientProtocolException e) {
 
                        // TODO Auto-generated catch block
 
                        e.printStackTrace();
 
                } catch (IOException e) {
 
                        // TODO Auto-generated catch block
 
                        e.printStackTrace();
 
                }
 
                this.setContentView(R.layout.main);
 
        }
Parsed in 0.034 seconds,  using GeSHi 1.0.8.4

The url should be end up something like http:x.com/bla.aspx?userId=1234&apiKey=48BkS4t

Thanks for the help,
Rick

Maybe you could give us more information about the Exception thrown

Somehow I never see a stacktrace, but in the debugger the detailMessage of 'e' it just says "unknown error"

I think I found the solution .... inside the AndroidManifest.XML I have to set a permission to access the Internet

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