Android assistant - MediaBrowserService - Voice command - "Play x on appName"

The voice commande Play [song] on [my appName] command not working, the "appName" is not being recognised by google assistante.
I followed the instruction form https://developer.android.com/guide/topics/media-apps/interacting-with-assistant and the demo app form https://github.com/android/uamp
My AndroidManifest:
<application
android:name=".XApplication"
android:allowBackup="false"

android:label="#string/app_name" // app_name = appX 101.1

I have a problem figuring out what I did wrong or what I missed . Any help will be greatly appreciated..
PS: My app had been in the store for 4days and my App Name have numbers in it like "appX 101.1" (i'm worried that this may be an issue)

Android studio unable to recognize default activity after changing it in manifest file

I've an android app where LoginActivity was main activity. I created a SplashScreen activty, then changed AndroidManifest as given below
<?xml version="1.0" encoding="utf-8"?>

When I try to run modified android app, it shows error as given below:
Error running app: Default activity not found.
I've added
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<action android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
to SplashActivity. But it isn't recognizing that as default activity. How can I fix it?

This should be category instead of action so use this
<category android:name="android.intent.category.LAUNCHER"/>
instead of
<action android:name="android.intent.category.LAUNCHER"/>
<activity
android:name=".main.SplashActivity"
android:configChanges="orientation|screenSize"
android:exported="false"
android:label="#string/app_name"
android:launchMode="singleTop"
android:theme="#style/DellTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>

Please let me Know where am i doing the mistake, and what would be the solution...???

Move the intent-filter tag from service to activity

These lines should be in Activity tag
<application
android:label="#string/app_name"
android:icon="#drawable/icon">
<activity
android:label="#string/wallpaper_settings"
android:name=".ParallaxWallpaperSettings"
android:theme="#android:style/Theme.Black.NoTitleBar" android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:label="#string/app_name"
android:name=".ParallaxWallpaper"
android:permission="android.permission.BIND_WALLPAPER">
</service>
<meta-data android:name="android.service.wallpaper" android:resource="#xml/wallpaper" />
</application>

make activity as launcher you have made service as launcher. like that
<activity
android:label="#string/wallpaper_settings"
android:name=".ParallaxWallpaperSettings"
android:theme="#android:style/Theme.Black.NoTitleBar"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
