searchManager.getSearchableInfo(getComponentName()) returns null

Question

I've followed this Android guide in order to add a search bar to an activity. The setup looks like this:

res/menu/activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@+id/search"
    android:title="@string/menu_search"
    android:icon="@android:drawable/ic_menu_search"
    android:showAsAction="collapseActionView|ifRoom"
    android:actionViewClass="android.widget.SearchView" />
<item
    android:id="@+id/menu_settings"
    android:orderInCategory="100"
    android:showAsAction="never"
    android:title="@string/menu_settings"
    android:icon="@drawable/ic_menu_settings"/>

</menu>

res/xml/searchable.xml:

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="@string/search_hint" />

Activity entry in manifest file:

    <activity
        android:name="de.ivu.realtime.app.activity.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
        <meta-data
            android:name="android.app.default_searchable"
            android:value="de.ivu.realtime.app.activity.MainActivity" />
    </activity>

and the code in MainActivity:

@SuppressLint("NewApi")
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    this.getMenuInflater().inflate(R.menu.activity_main, menu);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
    {
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
        SearchableInfo searchableInfo = searchManager.getSearchableInfo(getComponentName());
        searchView.setSearchableInfo(searchableInfo);
    }

    return true;

The call to searchManager.getSearchableInfo(getComponentName()); always returns null. I've seen this in other questions on stackoverflow, however, none of the solutions presented there seem to apply to my case.

the menu XML has a <?xml version="1.0" encoding="utf-8"?> header
the searchable XML has no hard-coded strings
renaming the menu item does not work
cleaning and rebuilding does not do the trick either

Any help is very much appreciated. Thanks!

Thank you for the summary of possible sources of errors! I had hard coded strings in searchable. — Michele Dorigatti, Aug 06 '20 at 19:38

Add it to the activity where you've put your SearchView

<meta-data
    android:name="android.app.default_searchable"
    android:value=".activity_that_handles_the_search" />

<intent-filter>
    <action android:name="android.intent.action.SEARCH" />
</intent-filter>

Thanks for your reply. The `SearchView` is in the `ActionBar` (see updated question). Since the `MainActivity` has the resources to provide search results, I've added your code to the `MainActivity`-section of the manifest. Still, `searchManager.getSearchableInfo(getComponentName());` returns `null`. – Chris Jan 25 '13 at 08:53
Updated the answer. Try to apply yet another the intent-filter as well. – Yaroslav Mytkalyk Jan 25 '13 at 10:10
Thanks, it works! Using this other guide http://developer.android.com/guide/topics/search/search-dialog.html, I just figured this out, too :-). – Chris Jan 25 '13 at 10:13
This code goes in the manifest, in case somebody is wondering. – Michele Dorigatti Aug 06 '20 at 19:31

In my case the problem was my mistake during integration with ActionBarSherlock. In this case android:actionViewClass should be com.actionbarsherlock.widget.SearchView instead of android.widget.SearchView. I know this sounds dumb, but I spent 20 minutes trying to figure out why searchView is null in my code that is similar to yours.

My issue was the other way around. I had integrated ActionBarSherlock and this was removed in an app update. com.actionbarsherlock.widget.SearchView needed to be removed and replaced with android.widget.SearchView – Craig Champion Apr 28 '15 at 11:51

Replace:

android:actionViewClass="android.widget.SearchView"

With:

app:actionViewClass="android.widget.SearchView"

Because app is often used if you are using support library.
