Agora provides an open-source OpenLive-Voice-Only-Android sample project on GitHub. This document introduces how to run this project and experience a live audio streaming implemented by the Agora SDK.

Prerequisites

• Development environment requirements:
  • Java Development Kit
  • Android Studio 3.0 or later
• If your network has a firewall, follow the instructions in Firewall Requirements to access Agora services.
• A real Android device. Agora recommends you run this sample project on a physical mobile device, as some simulators may not support the full features of this project.
• A valid Agora account.

Procedure

1. Create an Agora project

To create an Agora project, do the following:

1. Enter the Project Management page.
2. Click Create.
3. Follow the on-screen instructions to enter a project name and use case, and check Secured mode: APP ID + Token (Recommended) as the authentication mechanism.
4. Click Submit, and you can see the project on the Project Management page.

2. Get an App ID

Agora automatically assigns each project an App ID as a unique identifier.

To copy this App ID, find your project on the Project Management page in Agora Console, and click the copy icon to the right of the App ID.

3. Generate a temporary token

To ensure communication security, Agora recommends using tokens to authenticate users joining a channel.

For testing purposes, Agora Console supports generating RTC temporary tokens. To generate an RTC temporary token:

1. On the Project Management page, click the icon for your project.
2. On the Token page, enter the name of the channel that you want to join, and click Generate Temp Token. When joining the channel later, ensure that the channel name is the same with the one that you use to generate the temporary token.

4. Configure the sample project

1. Download the Basic-Audio-Broadcasting repository.
2. Find the Basic-Audio-Broadcasting/OpenLive-Voice-Only-Android sample project. Fill in the app/src/main/res/values/strings.xml file with the App ID and temporary token generated in Agora Console.

   // Replace <#YOUR APP ID#> with your App ID in the string format
   <string name="agora_app_id"><#YOUR APP ID#></string>
   // Replace #YOUR ACCESS TOKEN# with your temporary token in the string format
   <string name="agora_access_token">#YOUR ACCESS TOKEN#</string>

5. Integrate the Agora SDK

Integrate the Agora Voice SDK into the sample project, as follows:

1. Download the latest version of the Agora Voice SDK and extract the files from the downloaded package.

2. Copy the following files or subfolders from the libs folder of the SDK package to the corresponding folder of the sample project:

   File/Folder	Path
   agora-rtc-sdk.jar	/app/libs/
   arm-v8a folder	/app/src/main/jniLibs/
   armeabi-v7a folder	/app/src/main/jniLibs/
   x86 folder	/app/src/main/jniLibs/
   x86_64 folder	/app/src/main/jniLibs/

6. Build and run the sample project

Connect the Android device to your computer, open the OpenLive-Voice-Only-Android sample project on Android Studio, and then build and run the project.

After the IDE successfully installs the app on your Android device, you can see the following user interface:

You have joined the test channel by default. If you want to experience a live audio streaming, you can use the Agora Web demo app to interact with your Android device. Ensure that you enter the same App ID, channel name, and temporary token in the Agora Web demo app.
