Version 6.x.x of the Android SDK doesn't itself introduce any API changes. However as the SDK was refactored to Kotlin, if you're using it in Java application you have to add Kotlin runtime library as a dependency. See Changelog for more information.
The Sinch Voice and Video SDKs are available for iOS, Android and JavaScript. The downloads provide Sinch SDK Framework for Voice and Video, as well as documentation and sample applications for app-to-app calling, app-to-phone calling, and conference calling and video.
Google Play - Starting November 1st, 2025, all new apps and updates to existing apps submitted to Google Play and targeting Android 15+ devices must support 16 KB page sizes on 64-bit devices.
Sinch customers MUST upgrade to Android SDK 6.14.5 or newer, to be compatible with such requirement!

Instead of downloading the compressed file directly, you can also use the SDK from npm. To include it in your application, simply install it as a dependency:
npm install sinch-rtcSee sinch-rtc on npm for more details.
Instead of downloading the AAR file directly, you can also use the SDK from Maven Central. To include it in your application, simply add it as a dependency in your module’s build.gradle (usually app/build.gradle) file:
// app/build.gradle
dependencies {
implementation "com.sinch:voice-video-android:6.21.4"
}
