    <p>In your layout code as you have used the <code>Fragment</code> layout you need to provide some class to load in that <code>Fragement</code> layout as below:</p> <pre><code> &lt;fragment android:name="com.example.android.fragmentclass" android:id="@+id/listFragment" android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt; </code></pre> <p>As there are two ways to implement the <code>Fragment</code></p> <ul> <li><strong>Declare the fragment inside the activity's layout file.</strong></li> </ul> <p>In this case, you can specify layout properties for the fragment as if it were a view. For example, here's the layout file for an activity with two fragments:</p> <pre><code> &lt;fragment android:name="com.example.android.fragmentclass" android:id="@+id/listFragment" android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt; </code></pre> <p>The <code>android:name</code> attribute in the <code>&lt;fragment&gt;</code> specifies the <code>Fragment</code> class to instantiate in the layout. When the system creates this activity layout, it instantiates each fragment specified in the layout and calls the <code>onCreateView()</code> method for each one, to retrieve each fragment's layout. </p> <ul> <li><strong>Another is to define programmatically add the fragment to an existing ViewGroup.</strong></li> </ul> <p>You can then add a fragment using the <code>add()</code> method, specifying the fragment to add and the view in which to insert it.</p> <p>For example:</p> <pre><code>FragmentManager fragmentManager = getFragmentManager() FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); ExampleFragment fragment = new ExampleFragment(); fragmentTransaction.add(R.id.fragment_container, fragment); fragmentTransaction.commit(); </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.

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).
