Android Platform: Cannot run / compile example projects. 'ObjectManipulator' does not contain a definition for 'OnManipulationEnded'

[polygonfuture]

Overview

After setting up MRTK in a new Unity Project for Oculus Quest 2 (Android) using OVR Plugin, I am getting compile errors about missing definitions related to ObjectManipulator.

After opening any of the Sample Scenes I receive the following errors related to ObjectManipulator.

Assets\Samples\Mixed Reality Toolkit Examples\2.7.2\Demos - UX\ManipulationHandler\Scripts\ChangeManipulation.cs(52,43): error CS1061: 'ObjectManipulator' does not contain a definition for 'ForceEndManipulation' and no accessible extension method 'ForceEndManipulation' accepting a first argument of type 'ObjectManipulator' could be found (are you missing a using directive or an assembly reference?)

Assets\Samples\Mixed Reality Toolkit Examples\2.7.2\Demos - UX\BoundsControl\Scripts\BoundsControlRuntimeExample.cs(150,20): error CS1061: 'ObjectManipulator' does not contain a definition for 'OnManipulationStarted' and no accessible extension method 'OnManipulationStarted' accepting a first argument of type 'ObjectManipulator' could be found (are you missing a using directive or an assembly reference?)


Assets\Samples\Mixed Reality Toolkit Examples\2.7.2\Demos - UX\BoundsControl\Scripts\BoundsControlRuntimeExample.cs(151,20): error CS1061: 'ObjectManipulator' does not contain a definition for 'OnManipulationEnded' and no accessible extension method 'OnManipulationEnded' accepting a first argument of type 'ObjectManipulator' could be found (are you missing a using directive or an assembly reference?)


Assets\Samples\Mixed Reality Toolkit Examples\2.7.2\Demos - UX\BoundingBox\Scripts\BoundingBoxExampleTest.cs(145,20): error CS1061: 'ObjectManipulator' does not contain a definition for 'OnManipulationStarted' and no accessible extension method 'OnManipulationStarted' accepting a first argument of type 'ObjectManipulator' could be found (are you missing a using directive or an assembly reference?)

Assets\Samples\Mixed Reality Toolkit Examples\2.7.2\Demos - UX\BoundingBox\Scripts\BoundingBoxExampleTest.cs(146,20): error CS1061: 'ObjectManipulator' does not contain a definition for 'OnManipulationEnded' and no accessible extension method 'OnManipulationEnded' accepting a first argument of type 'ObjectManipulator' could be found (are you missing a using directive or an assembly reference?)

Also alternatively, pulling the unity packages directly from the git release does not give this error. (There are other build issues with this method, but it does not give this issue).

Expected behavior

Opening samples scenes give no compile error and run.

Actual behavior

Console gives errors about possible missing directives or assembly references related to ObjectManipulator.

Hi Kevin, I did follow these instructions directly. I’ve used MRTK for a Hololens production prior but the Quest 2 is new.

Just opened a PR to fix the issue. The fix will be included in 2.8.3. But please open bug reports against the Oculus integration package as this is caused by Meta not properly using namespace.
