+## 6. ProGuard rules
+
+If you use **R8/ProGuard** (`minifyEnabled true`), add the following rules to your `proguard-rules.pro` file to keep the Huawei HMS classes from being removed or obfuscated:
+
+```proguard
+-keep class com.huawei.hianalytics.**{*;}
+-keep class com.huawei.updatesdk.**{*;}
+-keep class com.huawei.hms.**{*;}
+```
+
+Without these rules, HMS components may be stripped during minification, causing crashes or initialization failures in release builds on Huawei devices.
