We used Mirrorfly for our project. When using Mirrorfly for the chat feature (core, messages, and chat), the size impact on your app will typically be around 2–3MB. The necessary SDKs come in .aar format, and to get the chat working, you will need to include the following components:

mirrorfly-android-sdk-core.aar – This includes the essential core functions such as authentication and user management (approximately 500KB). mirrorfly-android-sdk-chat.aar – This file is responsible for the chat functionalities (about 1MB). mirrorfly-android-sdk-messages.aar – It handles message sending, push notifications, and related tasks (around 500KB). These libraries allow you to integrate the chat feature with minimal impact on the app size.
