Integration

​

Before you start

• AndroidX: the sample project enables android.useAndroidX=true.
• Minimum OS version: the sample project’s minSdk is 24.
• Compile and target version: the sample project’s compileSdk / targetSdk is 35.
• Gradle repository configuration: prefer configuring repositories in settings.gradle (Gradle 7+); older projects can keep using the root build.gradle.

​

Configure the Maven repository

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
        maven { url 'https://maven.open.seastart.cn/repository/maven-vcs/' }
    }
}

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://maven.open.seastart.cn/repository/maven-vcs/' }
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://maven.open.seastart.cn/repository/maven-vcs/' }
    }
}

​

Add the SDK dependency

dependencies {
    implementation 'cn.seastart.rtc:rtc:<version>'
}

• groupId: cn.seastart.rtc
• artifactId: rtc
• version: replace with the SDK version you want to integrate

dependencies {
    implementation 'cn.seastart.rtc:rtc:2.0.35'
}

​

Integration notes

• Runtime permissions: if your app captures audio and video, request the CAMERA and RECORD_AUDIO permissions in your app.
• ABI compatibility: the SDK currently supports arm64-v8a and armeabi-v7a; include the ABIs that match your target devices.
• Background microphone capture: capture is decoupled from joining and publishing. If you need to keep calling LocalMicTrack.startCapture(...) in the background, configure a microphone-type foreground service and the related permissions as required by your Android version.
• Next steps: after adding the dependency, continue with Quickstart for RTCEngine.create(...), initSDK(), joining a channel, publishing, and subscribing. To manage output devices such as the speaker, earpiece, and Bluetooth headsets, see Audio routing (Chinese).

​

Media streaming and video display

• Supports the FY (Freewind) and Wangsu media streaming services, using the vendor configuration assigned by the server.
• For local preview and remote video display, use VcsPlayerGlTextureView or VcsPlayerGlSurfaceView from the cn.seastart.rtc.media.original.render package. Use the same package path in code imports and XML layouts. For usage, see Video rendering (Chinese).
• External video is fed through LocalCustomVideoTrack as unencoded I420 frames, and the SDK handles encoding and publishing. For integration, see Custom tracks (Chinese).
