How do you declare your AsyncTask class ? According to the <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="nofollow">AsyncTask documentation</a> <blockquote> The three types used by an asynchronous task are the following: Params, the type of the parameters sent to the task upon execution. Progress, the type of the progress units published during the background computation. Result, the type of the result of the background computation. Not all types are always used by an asynchronous task. To mark a type as unused, simply use the type Void. </blockquote> It should be something like : <pre><code>private class MyAsyncTask extends AsyncTask<Param, Progress, Result> </code></pre> This will define <code>doInBackground()</code> signature as follow : <pre><code>protected Result doInBackground(Param... params) </code></pre> You can then return the result at the end of <code>doInBackground()</code> instead of <code>null</code>. Edit : Applied to you example, it should look to something like this : <pre><code>public class MyAsyncTask extends AsyncTask<Void, int[], String> { protected Void doInBackground(Void... args) { request = new SoapObject(NAMESPACE, METHOD_NAME); username = new PropertyInfo(); username.setName("UserName"); username.setValue(Username); username.setType(String.class); request.addProperty(username); password = new PropertyInfo(); password.setName("Password"); password.setValue(Password); password.setType(String.class); request.addProperty(password); SoapSerializationEnvelope envp = new SoapSerializationEnvelope( SoapEnvelope.VER11); envp.dotNet = true; envp.setOutputSoapObject(request); HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); try { androidHttpTransport.call(SOAP_ACTION, envp); SoapPrimitive response = (SoapPrimitive) envp.getResponse(); // return your result here return response.toString(); } catch (Exception e) { e.printStackTrace(); } // return null if something went wrong return null; } @Override protected void onPostExecute(String result) { if (dialog != null) { dialog.dismiss(); dialog = null; } if (result == null) { // handle null here, for example : // result = "Fail"; } // use "Fail".equals(result) instead of result.equals("Fail") // to avoid error if result is null if ("Fail".equals(result)) { etPassword.setText(""); textValidation.setText("UserName Or Password is Wrong."); } else { etUsername.setText(""); etPassword.setText(""); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
