Configure obfuscation scripts before compiling the APK to prevent the HMS SDK from being obfuscated. If obfuscation arises, the HMS SDK may not function properly.
1. Open the obfuscation configuration file of your project.

2. Add configurations to exclude the HMS SDK from obfuscation.
- -ignorewarnings
- -keepattributes *Annotation*
- -keepattributes Exceptions
- -keepattributes InnerClasses
- -keepattributes Signature
- -keepattributes SourceFile,LineNumberTable
- -keep class com.hianalytics.android.**{*;}
- -keep class com.huawei.updatesdk.**{*;}
- -keep class com.huawei.hms.**{*;}
3. If you have used AndResGuard, add it to the whitelist in the obfuscation script file.
- "R.string.hms*",
- "R.string.connect_server_fail_prompt_toast",
- "R.string.getting_message_fail_prompt_toast",
- "R.string.no_available_network_prompt_toast",
- "R.string.third_app_*",
- "R.string.upsdk_*",
- "R.layout.hms*",
- "R.layout.upsdk_*",
- "R.drawable.upsdk*",
- "R.color.upsdk*",
- "R.dimen.upsdk*",
- "R.style.upsdk*",
- "R.string.agc*"
