Hey @Vardan,

(I assume you sorted this since. Sorry, I just started in this world recently and could not help earlier, however in case it helps someone:)

“package” is a duplicated in your tag, and again you have “android:name” twice in your first tag.

[Line 3]:
                package="com.unity3d.player" package="com.xtr3d.extrememotion"

...
[Line 14]:
    <activity android:name="com.prime31.UnityPlayerNativeActivity" 
               android:screenOrientation="landscape"
               android:launchMode="singleTask"
               android:label="@string/app_name"
               android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen"
android:name="com.xtr3d.extrememotion.Xtr3dOverrideProxyActivity">

(Edited/deleted because had a little glitch with special characters and the answer didn’t make much sense that way)

Hi @frankslater I’m getting the same error.
But I can’t see any duplicates on my code.
Can you please help me?
