    <p>I'm wondering if this is actually a bug in the Android API:</p> <p>I have a setup like so:</p> <pre><code>┌----┬---------┐ | | | | 1 | 2 | | |┌-------┐| | || || | || 3 || └----┴┴-------┴┘ </code></pre> <ol> <li>Is a menu which loads fragment #2 (A search screen) in the right pane.</li> <li>Is a search screen which contains fragment #3, which is a result list.</li> <li>The result list is used in several places (including as a functioning high level fragment in it's own right).</li> </ol> <p>This functionality works perfectly well on a phone (Where 1 &amp; 2 and 3 are <code>ActivityFragment</code>s). </p> <p>However, when I used this code:</p> <pre><code> FragmentTransaction transaction = getSupportFragmentManager().beginTransaction(); Fragment frag = new FragmentNumber2(); if(toLoad != null) frag.setArguments(toLoad); transaction.replace(R.id.rightPane, frag); transaction.commit(); </code></pre> <p>Where <code>R.id.leftPane</code> and <code>R.id.rightPane</code> are <code>&lt;fragment&gt;</code>s in a horizontal linear layout.</p> <p>It is my understanding that the above code removes the fragment which is resident and then replaces it with a new fragment. Brilliant... Obviously that isn't what happens because when this code runs the second time you get the following exception:</p> <pre><code>07-27 15:22:55.940: ERROR/AndroidRuntime(8105): Caused by: java.lang.IllegalArgumentException: Binary XML file line #57: Duplicate id 0x7f080024, tag null, or parent id 0x0 with another fragment for FragmentNumber3 </code></pre> <p>This is caused because the the container for FragmentNumber3 has been duplicated and it no longer has a unique ID. The initial Fragment hasn't been destroyed (?) before the new one is added (in my mind that means it hasn't been <em>replaced</em>).</p> <p>Can someone tell me if this is possible (<a href="https://stackoverflow.com/questions/5268361/fragments-in-action-bar-tab-fragments/5280000#5280000">this answer</a> suggests it isn't) or is it a bug?</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.

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