    <p>first you declare your parent class with all common behavior</p> <pre><code>public abstract class MyAbstractTask extends AsyncTask&lt;String, String, String&gt; { protected void someMethod() { //note that i change private to protected final RestAdapter restAdapter = new RestAdapter.Builder().setServer("http://10.0.2.2:8080").build(); final MyTaskService apiManager = restAdapter.create(MyTaskService.class); } } </code></pre> <p>then, you extend it with every task</p> <pre><code>public class MyTask extends MyAbstractTask { //your someMethod() is available from everywhere in your class } public class MyOtherTask extends MyAbstractTask { //your someMethod() is available from everywhere in your class } </code></pre> <hr> <p>but i dont know where you are using restAdapter and apiManager, and if the actually need to be created once per task, since probably you can create it outside of these tasks. </p> <p>If you create them outside, and then you need to use something inside your task, it is also good to have in mind the <a href="http://en.wikipedia.org/wiki/Dependency_injection" rel="noreferrer">Dependency_injection</a> pattern.</p> <hr> <p>Also, you should avoid hardcoding values in your classes, like <code>http://10.0.2.2:8080</code> </p> <p>You should use at least a <code>final static final String server= "http://10.0.2.2:8080"</code> and then use that, or better, use a setter or the constructor in the most inner class, and set tha values from the activity or the main controller. </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.
