Building for mobile AR with Vuforia
We've shown how to build the project for Microsoft HoloLens wearable AR devices and mobile iOS devices that support ARKit. But this is a limited market, as there are many more mobile devices that run Android, as well as Apple devices that do not support ARKit. In this section, we will adapt the project for mobile devices using the Vuforia toolkit SDK. Unfortunately, these devices are not capable of supporting spatial maps to anchor our AR graphics. Instead, we will use image targets.
A traditional approach used for more than two decades is to print marker images and tape them to the walls. Vuforia and AR Toolkit support the ability to recognize multiple targets concurrently. That is the approach we will take now.
If you have been following along and have already built the HoloLens or ARKit version of the project, we strongly suggest you save your work and copy the entire project directory tree for the Vuforia version. There are incompatibilities between...
