    <blockquote> <p>What do i have to write into onPostExecute and the Activity grab the string from doInBackground?</p> </blockquote> <p>When you are using <code>AsyncTask</code> then you can update your <code>UI</code> only on <code>onProgressUpdate</code> and <code>onPostExecute</code> method. <br><br>Your <code>doInBackground()</code> method returns some data and these data is going to <code>onPostExecute</code> method(it depends also how your generic are declared). <br><br>Generally, there is no another approaches how to do it.</p> <p>You meant this:</p> <pre><code>AsyncTask a = new AsyncTask(Context); a.execute(Input); </code></pre> <p>First means that your constructor looks like</p> <pre><code>public MyAsync(Context c) { this.c = c; } </code></pre> <p>Second means that you declared your first generic type(assumption Input param is <code>String</code>) as</p> <pre><code>private class MyAsync extends AsyncTask&lt;String, Void, String&gt; { //... } </code></pre> <p><br>And you want to update <code>UI</code> with <code>String</code> that returns <code>doInBackground()</code> method and merely place is <code>onPostExecute</code> method with <code>IN</code> parameter <code>String</code> that returns <code>doInBackground()</code>.<br><br></p> <pre><code>protected void onPostExecute(String stringReturnedFromDoInBackground) { // some work } </code></pre> <p><br>So if you want to do it in different way, change your application logic and use for example <code>ResultReceiver</code> with <code>IntentService</code>.</p>

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.
