    my android manifest sure has the activity UnityPlayerNativeActivity mentioned in it as shown below:


    
<activity android:name="com.unity3d.player.UnityPlayerNativeActivity" android:label="[USER=7078]@String[/USER]/app_name">
    
      <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
    
      <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" />
    
      <intent-filter>
    
        <action android:name="android.intent.action.MAIN" />
    
        <category android:name="android.intent.category.LAUNCHER" />
    
      </intent-filter>
    
    </activity>


    I don't know why UnityPlayerNativeActivity is showing as not found in my app and giving the error. The current Unity version is 2018.3.3f1 and the Facebook SDK version is 7.15.1. Can someone please tell me a solution for this issue?
