    <p>I'm trying to add a Search-ActionView to my application (as explained here <a href="http://developer.android.com/guide/topics/search/search-dialog.html#UsingSearchWidget" rel="noreferrer">http://developer.android.com/guide/topics/search/search-dialog.html#UsingSearchWidget</a>). Unfortunately I keep getting a NullPointerException and I'm having a hard time detecting what's actually going wrong.</p> <p>I created a searchable config and a searchable activity as shown on the android page. My menu .xml file looks like this:</p> <pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android" &gt; ... &lt;item android:id="@+id/menu_item_search" android:actionViewClass="android.widget.SearchView" android:icon="@drawable/icon_search" android:showAsAction="always" android:title="@string/action_bar_button_search"&gt; &lt;/item&gt; &lt;/menu&gt; </code></pre> <p>This is the method where the Exception is thrown:</p> <pre><code>public boolean onCreateOptionsMenu( Menu menu ) { MenuInflater menuInflater = getMenuInflater(); menuInflater.inflate( R.menu.action_bar, menu ); SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); SearchView searchView = (SearchView) menu.findItem(R.id.menu_item_search).getActionView(); // NullPointerException thrown here; searchView is null. searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); searchView.setIconifiedByDefault(false); return super.onCreateOptionsMenu( menu ); } </code></pre> <p>Complete stack trace:</p> <pre><code>FATAL EXCEPTION: main java.lang.NullPointerException at com.example.activities.Test.onCreateOptionsMenu(Test.java:41) at android.app.Activity.onCreatePanelMenu(Activity.java:2444) at com.android.internal.policy.impl.PhoneWindow.preparePanel(PhoneWindow.java:408) at com.android.internal.policy.impl.PhoneWindow.invalidatePanelMenu(PhoneWindow.java:759) at com.android.internal.policy.impl.PhoneWindow$1.run(PhoneWindow.java:2997) at android.os.Handler.handleCallback(Handler.java:605) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4507) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:790) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:557) at dalvik.system.NativeStart.main(Native Method) </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).
