App size optimization

Reducing the app size is of great significance in improving user experience. A smaller package size means that users consume less bandwidth and time to download the app. Consider the following scenarios where app size optimization is critical:

• There are strict requirements on the size of the app. For example, running the app on smart wearable devices with limited storage space.

• The target user group of the app is located in underdeveloped areas. The poor network connectivity causes the app download time to be too long.

This page shows you how to optimize the size of apps with integrated Video SDK.

Since version 4.4.0, Agora offers a Lite SDK that provides basic audio and video call functions in a smaller package size. If you only need to implement basic audio and video call functions, integrate the Lite SDK. For details see SDKs.

The Lite SDK includes only the following extensions:

• Video encoding extension
• Video decoding extension

Other extensions and related functions in the Extension list are not supported.

Video SDK supports both audio and video functions, and the package size is large. If you only need to use audio features, best practice is to integrate the Voice SDK. For details, see Voice SDK Quickstart.

Video SDK provides optional extension dynamic libraries. The name of the extension is suffixed with extension. See the extension list for details on the function and size of the extensions. Refer to the following ways to exclude these extensions to reduce the size of the app.

When integrating through the Direct download link, manually delete the extension files that you do not need to use.

When integrating the Android SDK through Maven Central, you can modify the /Gradle Scripts/build.gradle(Module: <projectname>.app) file to specify the dynamic libraries you need to integrate and exclude extensions you do not need to use. For details on the correspondence between each file in the Android SDK and the fields in dependencies, see implementation fields for details.

Refer to the following samples to include, all, none, or selected extensions.

Use all extensions

dependencies {  implementation 'io.agora.rtc:full-sdk:4.0.1'  implementation 'io.agora.rtc:full-screen-sharing:4.0.1'  // ...}

Don't use any extensions

dependencies {  implementation 'io.agora.rtc:full-rtc-basic:4.0.1'  //...}

Use selected extensions

dependencies {  def agora_sdk_version = "4.3.0"  // The following code contains $, so you must use double-quotes  implementation "io.agora.rtc:full-rtc-basic:${agora_sdk_version}"  implementation "io.agora.rtc:full-ains:${agora_sdk_version}"  implementation "io.agora.rtc:audio-beauty:${agora_sdk_version}"  //...}

Generally, you package the required .so files when compiling the App, and the SDK loads the .so files from the nativeLibraryPath of the App. To reduce the size of the app's installation package, Video SDK provides the mNativeLibPath attribute in the RtcEngineConfig class to support dynamic loading of the required .so files.

Note

• Since March 6, 2024, using this method to reduce the app size no ​​longer meets the requirements of Google Play. For details, refer to the Developer Program Policies issued by Google. If your app needs to be listed on Google Play, please try other ways to reduce the app size.

• This method is only applicable to manually integrating the Android SDK and does not apply to integration through Maven Central.

Refer to the following steps to implement this feature:

1. Download the latest version of the SDK and decompress it.
2. Integrate agora-rtc-sdk.jar into your project.
3. Upload the .so files for all architectures to your server and make sure that the app can download the .so files for the target architecture over the network.
4. When the app runs, it checks for the existence of an .so file. If the file is not found, it downloads the .so file and saves it to the private directory of the app.
5. When calling create to create and initialize an RtcEngine instance, set the mNativeLibPath config parameter to the app private directory where the .so file is located.
6. After calling create successfully, the SDK automatically loads the .so file from the specified path.

Refer to the following information for an introduction to each Video SDK extension and the increase in the size of your app after integration.

Information

The information in this section is based on version 4.4.0 of the Video SDK.
