Java

Introduction

In this tutorial, you will learn how to create an Android application using Java and the Android Client SDK, and then write the code to receive a phone call to your Android app from a phone.

Two parts are needed to achieve this:

  • An Android application that will receive the voice call using the Client SDK.
  • A publicly accessible URL that serves instructions on how to handle the call. To accomplish this, you will create a webhook server using Node.js, Express and localtunnel.

Completed project

If you would like to follow along without building the app yourself, the completed project is available on Github - please see the phone-to-app-java folder.
