# Proguard configuration

> Proguard rules required to prevent essential Duix SDK classes from being obfuscated during release builds.

## Overview

When building a **release version** of your app with code shrinking or obfuscation enabled\
(e.g., using **Proguard** or **R8**), certain SDK dependencies must be excluded from obfuscation\
to ensure stable runtime behavior.

Add the following rules to your project’s **`proguard-rules.pro`** file:

***

```proguard theme={null}
# Prevent WebRTC classes from being obfuscated
-keep class org.webrtc.** { *; }

# Preserve MQTT client classes
-keep class org.eclipse.paho.client.** { *; }
-keep class org.eclipse.paho.uri.** { *; }

# (Optional) Preserve Duix SDK classes if referenced by reflection
-keep class com.guiji.sdk.** { *; }
```
