AndroidManifest.xml Problem

[LightLion]

Hey, I am trying to upload my app into applab but it won't accept it
I am getting this error :
* ‎APK install location should be `auto` (android:installLocation in AndroidManifest.xml). See documentation at: https://developer.oculus.com/distribute/publish-mobile-manifest/‎
and something about android:screenOrientation in AndroidManifest.xml

I tried adding android:screenOrientation in AndroidManifest.xml and it didn't  work and Even without its still not working

and the apk location is on auto 

I added both but its still not accepting it for some reason

my AndroidManifest :

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="auto">
  <application android:label="@string/app_name" android:icon="@mipmap/app_icon" android:allowBackup="false">
    <activity android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" android:configChanges="locale|fontScale|keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode" android:screenOrientation="landscape" android:launchMode="singleTask" android:name="com.unity3d.player.UnityPlayerActivity" android:excludeFromRecents="true">
      <intent-filter>
  <action android:name="android.intent.action.MAIN" />
  <category android:name="com.oculus.intent.category.VR" />
  <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
    </activity>
    <meta-data android:name="unityplayer.SkipPermissionsDialog" android:value="false" />
    <meta-data android:name="com.samsung.android.vr.application.mode" android:value="vr_only" />
    <meta-data android:name="com.oculus.supportedDevices" android:value="quest|quest2" />

  </application>
  <uses-feature android:name="android.hardware.vr.headtracking" android:version="1" android:required="true" />
</manifest>

 What should I do ?
