system – Searches for files in all subdirectories of a directory

I need to find a file in all subdirectories of the Netflix folder. The file’s name is in this code section of AndroidManifest.xml:

<activity android:name=".ui.launch.UIWebViewActivity" enabled="@bool/phone" theme="@style/Theme.Netflix.Default.FullScreen">                                                                  
 <intent-filter>                                                   
  <action android:name="android.intent.action.MAIN"/>                                                                         
  <category android:name="android.intent.category.LAUNCHER"/>                                                             
 </intent-filter>                                          
</activity>

As you can see in the first line of this section of code, it references the file .ui.launch.UIWebViewActivity I need to find this file. I already ran find -name .ui.launch.UIWebViewActivity but this file is not in the root folder, it can be in any subdirectory right?
