How To: Build an Augmented Reality Remote Assistance App in Android

In this article, we learn how to build an Android app that uses ARCore and video chat to create an interactive remote assistance experience. The app allows users to join a channel as a streamer or audience, with the streamer broadcasting their rear camera to the audience. The audience can draw on their own device and have the touch input rendered in augmented reality in the streamer's world. We go through setting up the project, integrating SDKs, creating user interfaces, enabling ARCore, setting up video calls for both users, and implementing a remote assistance feature that allows the audience to interact with the streamer's AR world by drawing on their own device. The final result is an app that enables seamless remote support through augmented reality and video chat.
