Integrating The SDK

Three main sections here are: Adding Jitpack - Since you need to retrieve the 100ms Android SDK. Adding the 100ms SDK - To add the SDK to your project's dependencies. Adding Permissions - Since a video calling app needs camera/record-audio permissions you'll need this for the apps to work.

Adding Jitpack

The 100ms SDK is distributed via Jitpack.

Add the JitPack repository to your root settings.gradle at the end of the respositories closure: You can open it in Android Studio by double tapping the Shift key and typing settings.gradle. It will be in your project root.

 
dependencyResolutionManagement {
 repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
 repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
        maven { url 'https://jitpack.io' }
    }
}
rootProject.name = "MyVideoCallApp"
include ':app'

Adding the 100ms SDK

Add the 100ms sdk dependency to your app-level build.gradle .

You'll also need the webrtc dependency for the org.webrtc.SurfaceViewRenderer that's required to display people's videos.

 
dependencies {
    // See the version in the jitpack badge above.
    implementation 'com.github.100mslive:android-sdk:x.x.x' 
    implementation 'org.webrtc:google-webrtc:1.0.32006'
}

Permissions

Camera, Recording Audio and Internet permissions are required. Add them to your manifest.

 
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.INTERNET" />

You will also need to request Camera and Record Audio permissions at runtime before you join a call or display a preview. Please follow Android Documentation for runtime permissions.
