    <p>Hi and thank you for any help.</p> <p>I am only at the very beginning of configuring my code to handle rotation: I have implemented onDestroy(), but not yet any onSaveInstanceState() or onRetainNonConfigurationInstance() because I am figuring out what will not cause problems if destroyed and recreated after rotation and what needs to be saved.</p> <p>In my application I use a Service that runs an AsyncTask, and 3 fragments that get swapped on user pressing buttons.</p> <p>I use the compatibility library for managing the fragments.</p> <p>I suspect the error I encounter is related to the fragments;</p> <p><strong>To be specific, I would prefer the fragments to be destroyed and recreated on rotation, rather that preserving them (because it is my hope that this would make my code simpler...)</strong></p> <p>when I rotate the emulator I get the error in the title.</p> <p>This is the code of the main activity:</p> <pre><code>public class Quotes extends FragmentActivity { private String url2;

    2. COI mean to say if it is not alllowing you to pop back fragments in OnDestroy then write that code in onConfigurationChanged Method, this will be called on orientation change

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
