Requirements

Getting Started

In order to run this application on an Android device or emulator, complete the following steps.

Deploy Twilio Access Token Server

NOTE: The Twilio Function that provides access tokens via a passcode should NOT be used in a production environment. This token server supports seamlessly getting started with the collaboration app, and while convenient, the passcode is not secure enough for production environments. You should use an authentication provider to securely provide access tokens to your client applications. You can find more information about Programmable Video access tokens in this tutorial.

The app requires a back-end to generate Twilio access tokens. Follow the instructions below to deploy a serverless back-end using Twilio Functions.

1. Install Twilio CLI.
2. Run twilio login and follow prompts to login to your Twilio account.
3. Run twilio plugins:install @twilio-labs/plugin-rtc.
4. Run twilio rtc:apps:video:deploy --authentication passcode.
5. The passcode that is output will be used later to sign in to the app.

The passcode will expire after one week. To generate a new passcode, run twilio rtc:apps:video:deploy --authentication passcode --override.

Troubleshooting The Twilio CLI

If any errors occur after running a Twilio CLI RTC Plugin command, then try the following steps.

1. Run twilio plugins:update to update the rtc plugin to the latest version.
2. Run twilio rtc:apps:video:delete to delete any existing authentication servers.
3. Run twilio rtc:apps:video:deploy --authentication passcode to deploy a new authentication server.
