You will likely need to edit your gradle files to include this file.
I haven't tested this yet, but it will probably be something like this:

android/settings.gradle

include ":xrmanifest.androidlib"
project(":xrmanifest.androidlib").projectDir = file("./unityLibrary/xrmanifest.androidlib")

android/app/build.gradle

  dependencies {
+        implementation project(':xrmanifest.androidlib')
     }

thanks, but it fails with the same error :(

Did you find a solution ? I have the same issue.

[khangpt]

me too T_T

I'm not sure this is a solution to make the build is successful. But when I make same with @timbotimbo said, also comment out this line "implementation project('xrmanifest.androidlib')" in unityLibrary/build.gradle ==> flutter run is OK.

But, when run android device, I got below:

This is log on my console:

This is how I'm using the widget in Flutter:

Hope anybody can help

Just made a project to test this out.

Apparenty xrmanifest.androidlib is a new folder and not a file like I expected, located in /unityLibrary.

Adding a line to android/settings.gradle made it compile again for me.

  include ":unityLibrary"
  project(":unityLibrary").projectDir = file("./unityLibrary")

+ include ':unityLibrary:xrmanifest.androidlib'

I got this from /unity/<project folder>/Builds/settings.gradle which was generated by Unity. The builds folder is the original build created on an export and parts of that get moved to android/unityLibrary for this plugin.

While testing this ARFoundation ran into issue #836, the error with mUnityplayer in @khangpt's screenshot above.
This means it is likely broken (for now) starting with the Unity versions:

• 2020.3.46
• 2021.3.19
• 2022.2.4
  If you want it to work right now, use a version below these, like 2021.3.18 or 2022.2.3.

include ':unityLibrary:xrmanifest.androidlib'

this, combined with that, apparently solved the problem: the application is built and it runs on the device, but the AR camera is not open and this error comes out:

is that related to the original issue?

[timbotimbo]

That is a different breaking change in Unity, the last section with mUnityplayer I mentioned above.

oh, that's ok, so i'll close this issue, thanks so much.

anyway, on my device, using version 2022.2.21f1 i can see the 3d scene (just a cube) but on a black background, e.g., no camera feedback.

with version 2022.2.0f1 it fails to build.

any idea on that?

I think you should try to enable camera permission on your device first. Hope this help

Any one have any solutions to this?
