OpenIM Docs • OpenIM Server • openim-sdk-android • openim-sdk-core

OpenIM provides an open-source Instant Messaging (IM) SDK for developers, serving as an alternative solution to cloud services like Twilio and Sendbird. With OpenIM, developers can build secure and reliable IM applications similar to WeChat.

This repository is based on the open source version of OpenIM SDK. You can use this Demo as a reference implementation of OpenIM SDK. @openim/android-client-sdk and @openim/core-sdk are referenced to create native Android applications.

Quick Start

Follow these steps to set up your local development environment:

1. Clone the repository

   git clone https://github.com/openimsdk/open-im-android-demo.git
   cd open-im-android-demo
   

2. Open and Sync the dependencies

   • Use Android Studio to open the Demo folder in the project root directory as the App directory of the Android project

     Please note that you should open the Demo folder instead of directly opening the project root directory. We recommend that you first read the official doc to understand the composition of the Android project and the functions of different files in the project.

3. Modify the configuration

   • In the Constants.java file:

     After deployed OpenIM Server, you need to modified this file to ensure it works properly.

     public static final String DEFAULT_HOST = "your-server-ip or your-domain"
     

4. If you changed server's port, you need to modify the following code. If not, keep it for default.

   private static final String APP_AUTH = "http://" + DEFAULT_HOST + ":10008/";
   private static final String IM_API = "http://" + DEFAULT_HOST + ":10002";
   private static final String IM_WS = "ws://" + DEFAULT_HOST + ":10001";
   

5. Start developing and testing! 🎉

Audio/Video Calls
