How to integrate searchable Activity with Ok Google voice search?

Question

I am trying to implement the Ok Google Voice Search integration. However, I am unable to deeplink into my app when I say "Search for Android on app_name." Instead, it simply searches the term on the web.

Here's what I did:

1. Create /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">
   </searchable>
   

2. Create a new Activity

   public class ExposedSearchActivity extends Activity {
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
   
           String search = getIntent().getStringExtra(SearchManager.QUERY);
           Log.wtf("", "q=" + search);
       }
   }
   

3. Attach intent filters to the searchable activity

   <activity
       android:name=".search.ExposedSearchActivity"
       android:configChanges="orientation|keyboardHidden|screenSize"
       android:screenOrientation="fullSensor">
       <!--Deeplink from google now-->
       <intent-filter>
           <action android:name="com.google.android.gms.actions.SEARCH_ACTION"/>
           <category android:name="android.intent.category.DEFAULT"/>
       </intent-filter>
       <!--Making it searchable-->
       <intent-filter>
           <action android:name="android.intent.action.SEARCH"/>
       </intent-filter>
       <meta-data
           android:name="android.app.searchable"
           android:resource="@xml/searchable"/>
   </activity>
   

4. My test device is a Nexus 5 running Lollipop LPX13D with Google Search 4.0.26.1499465.arm

What other steps might I have forgotten? Thanks in advance.

As the above answer listed by Some Noob Student. i am going further for how to test it with debug apk with adding String in search query?

Open command prompt in your PC then change path to your adb path. then execute below commands.

Note: before executing below commands close your debug app then test.

1) adb shell am start -a com.google.android.gms.actions.SEARCH_ACTION -e query app_package_name

2)adb shell am start -a com.google.android.gms.actions.SEARCH_ACTION -e query "Hello" app_package_name
