Paraphrasing some troubleshooting steps from the Godot discord - the second one worked for me. I was using Godot 4.3 and Godot OpenXR Vendors latest (3.1.2-stable) at the time.

If your build is failing is failing with the below message, try these 2 steps:

• Confirm that you're using the correct andlatest version of Godot OpenXR Vendors
• Delete your res://android directory, and re-install the Android Build Templates (Project->Reinstall Android Build Templates...)

What went wrong:
  Execution failed for task ':mergeDebugNativeLibs'.
  > A failure occurred while executing com.android.build.gradle.internal.tasks.MergeNativeLibsTask$MergeNativeLibsTaskWorkAction
     > 2 files found with path 'lib/arm64-v8a/libopenxr_loader.so' from inputs:

I had a fail at mergeStandardDebugNativeLibs and your steps helped me. Thanks!

btw I'm using Godot 4.4 and OpenXR vendors 4.0 which are the latest at the time of this comment.

I would like to add one thing that I couldn't find on any Android-related page here (maybe my mistake?).
Folder names must not begin with "" (underscore), otherwise they will not be copied with the apk, and the app will fail to launch (on Quest, for example it will freeze with 3 dots on screen. It took me a while to troubleshoot that.
By the way, here's the pattern of the folder names to avoid for Android (from Android source code):
"!.svn:!.git:!.ds_store:!.scc:.:

:!CVS:!thumbs.db:!picasa.ini:!~";

This is where the ignore pattern is defined: https://github.com/godotengine/godot/blob/30bb49ec1ff3b3fc463074b8d28bc97d4db50b9f/platform/android/java/app/build.gradle#L98-L101

I'm not sure why _* has to be excluded by default. To my knowledge, Godot does not create such folders by itself.

@Calinou Android by default, excludes folders that start with an underscore. We decided to keep the default behaviour.

[syntaxerror247]

@dr-formalyst We have mentioned it at the end of the gradle build page: https://docs.godotengine.org/en/stable/tutorials/export/android_gradle_build.html

There seems to be an issue building for Android (Meta XR) with Godot 4.5 with C# support. I have followed the directions in this doc and verified that the expected versions of the NDK, JDK, SDK, etc are installed but keep getting the following error:

Exception org.jetbrains.kotlin.konan.target.TargetSupportException: Unknown hardware platform: x86 [in thread "Daemon worker Thread 4"]
