How can I reduce the app size after integrating the RTC Native SDK?
This page applies to SDKs earlier than v3.6.2 only. As of v3.6.2, Agora offers additional methods for reducing app size. See Reduce App Size for the latest details.
This article describes how to reduce the app size after integrating the RTC Native SDK.
Solution 1: Use the Audio SDK
The Video SDK supports both audio and video functions, so the package size is larger. If you only need to use the audio functions, Agora recommends integrating the Audio SDK.
Solution 2: Remove unnecessary extension libraries
The SDK provides extension libraries that can be optionally integrated into the project. The name of extension libraries is suffixed with Extension. For details, see Extension libraries.
If you do not need the extension functions, you can directly remove the corresponding extension libraries to reduce the app size.
Deep-learning noise reduction library
The SDK enables traditional noise reduction by default to reduce most of the stationary background noise. Deep-learning noise reduction adds non-stationary background noise reduction based on the traditional noise reduction. After integrating the deep-learning noise reduction library, you can call enableDeepLearningDenoise to enable the deep-learning noise reduction. See v3.3.0 Release Notes.

JND library (beta feature)
The JND (Just-noticeable difference) function is used for video perceptual coding, which reduces bandwidth consumption while keeping the same image quality. For example, this function can improve video smoothness in bandwidth-constrained scenarios, and reduce network traffic consumption in mobile network scenarios. To use this function, contact support@agora.io.
