[AR] ARCore XR Plugin is not installed by default #2

Open hybridherbst opened 4 years ago

This creates a lot of confusion, especially for beginners. Both ARCore and ARKit should "just work" out of the box on this sample repo.

Also, there should be a warning when using ARFoundation and building for Android without this present; right now you just get a black screen.

Preequisites: Unity Version : 2019.2 or later Packages required : ARFoundation, XR Interaction Toolkit, ARCore XR Plugin, ARKit XR Plugin Package Dependencies : ARSubsystems, XR Legacy Input Helpers

Unity Version: 2019.3 or later. Package: XR Interaction Toolkit is already loaded. If you "Switch Platform" to Android, you will need to "Install XR Plugin Management" at Project Settings, enable "ARCore" in Plug-in Providers section and set the minimum level of Android SDK to 24 (Android 7.0) at Other Settings of Player Settings. But even after doing them, the sample VR app didn't show in VR mode (dual windows). Why !?

And if you install the package 'AR Foundation' ver. 3.x, you will encounter the compile errors such as "error CS1061: 'XRCameraSubsystem' does not contain a definition for 'shaderName' ...".

If you use ver. 2.x of AR Foundation and AR Subsystems, the errors above don't occur. But still it shows only single window (non VR mode).

The fact that this issue has been open for 9 months with no comment is ridiculous. I can't even get the AR example working on Android (although I've managed to use AR Foundation without this toolkit on several previous projects).

After adding the ARcore package and enabling it, I get an instant crash after the splash screen and enabling camera permission:
