Learn about the XR widget to seamlessly run VR applications on our headset.

We'll cover the following...

Overview of ADB and WebADB

There are instances where we need our PC to interact with an external Android device. This can include installing an application directly from the local machine to our Android devices. Android Debug Bridge (ADB) is a command line tool that facilitates communication between Android phones and computers. This communication can involve file transfers.

Introduction to the XR widget

It’s common for VR development guides to become confusing when users can’t verify whether they were able to correctly follow the development and configuration instructions. To this end, we’ve introduced an XR widget so we can validate our progress at different checkpoints to see whether our local build is similar to the version offered via the XR widget.

The XR widget is designed to sideloadSideloading is installing an app on a device without using an official application store. APKs and execute commands via ADB Shell from the Educative platform into Android devices via USB cable. The user will see the XR widget as follows:

Here’s a guide on how to use the widget. The widget essentially sideloads the APKs that we’ve created from the Educative platform to our Meta Quest devices. It has two modes:

  • Browser mode, in which we need to configure a few local settings

  • Local mode, in which we need to copy and paste the command to experience VR

Mode 1: Browser (default)

The browser mode allows the Educative platform to directly interact with the Android device.

Prerequisites

There are a few configurations that need to be done to experience the APK or command.

  • Make sure that no other ADB server instances are running on our machine. If there is any server running, we must stop the process first. To stop the ADB process from the platform-tools directory, navigate to the following path:
