Is it possible to register android application in AndroidManifest.xml?

Current Android$$anonymous$$anifest.xml:

 <?xml version="1.0" encoding="utf-8"?>
 <manifest
     xmlns:android="http://schemas.android.com/apk/res/android"
     package="com.unity3d.player"
     android:installLocation="preferExternal"
     android:theme="@android:style/Theme.NoTitleBar"
     android:versionCode="1"
     android:versionName="1.0">
 
     <supports-screens
         android:smallScreens="true"
         android:normalScreens="true"
         android:largeScreens="true"
         android:xlargeScreens="true"
         android:anyDensity="true"/>
   
     <application
         android:name=".package.ClassName"
         android:icon="@drawable/app_icon"
         android:label="@string/app_name"
         android:debuggable="true">
 
         <activity
             android:name="com.unity3d.player.UnityPlayerNativeActivity"
             android:label="@string/app_name"
             android:hardwareAccelerated="true">
             
             <intent-filter>
                 <action android:name="android.intent.action.$$anonymous$$AIN" />
                 <category android:name="android.intent.category.LAUNCHER" />
                 <category android:name="android.intent.category.LEANBAC$$anonymous$$_LAUNCHER" />
             </intent-filter>
             <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
             <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" />
         </activity>
     </application>
 </manifest>
