Http Get using Android HttpURLConnection

Question

I'm new to Java and Android development and try to create a simple app which should contact a web server and add some data to a database using a http get.

When I do the call using the web browser in my computer it works just fine. However, when I do the call running the app in the Android emulator no data is added.

I have added Internet permission to the app's manifest. Logcat does not report any problems.

Can anyone help me to figure out what's wrong?

Here is the source code:

package com.example.httptest;  import java.io.IOException; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.URL; import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.widget.TextView;  public class HttpTestActivity extends Activity {     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);          TextView tv = new TextView(this);         setContentView(tv);          try {             URL url = new URL("http://www.mysite.se/index.asp?data=99");             HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();             urlConnection.disconnect();             tv.setText("Hello!");         }         catch (MalformedURLException ex) {             Log.e("httptest",Log.getStackTraceString(ex));          }         catch (IOException ex) {             Log.e("httptest",Log.getStackTraceString(ex));         }        }         }

Try getting the input stream from this you can then get the text data as so:-

    URL url;     HttpURLConnection urlConnection = null;     try {         url = new URL("http://www.mysite.se/index.asp?data=99");          urlConnection = (HttpURLConnection) url                 .openConnection();          InputStream in = urlConnection.getInputStream();          InputStreamReader isw = new InputStreamReader(in);          int data = isw.read();         while (data != -1) {             char current = (char) data;             data = isw.read();             System.out.print(current);         }     } catch (Exception e) {         e.printStackTrace();     } finally {         if (urlConnection != null) {             urlConnection.disconnect();         }         } 

You can probably use other inputstream readers such as buffered reader also.

The problem is that when you open the connection - it does not 'pull' any data.
