Configuring Obfuscation Scripts

Before building the APK, configure the obfuscation configuration file to prevent the HMS Core SDK from being obfuscated.

1. Open the obfuscation configuration file proguard-rules.pro in the app directory of your project, and add configurations to exclude the HMS Core SDK from obfuscation.

   -ignorewarnings
   -keepattributes *Annotation*
   -keepattributes Exceptions
   -keepattributes InnerClasses
   -keepattributes Signature
   -keepattributes SourceFile,LineNumberTable
   -keep class com.huawei.hms5gkit.**{*;}

2. If you are using AndResGuard, add its trustlist to the build.gradle file in the app directory of your project.

   "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*"

3. (Optional) Configure the keep.xml file as follows to keep layout resources if you have enabled R8 resource shrinking (with shrinkResources set to true in the project-level build.gradle file) and strict reference checks (with shrinkMode set to strict in the res/raw/keep.xml file). Not keeping layout resources will lead to app rejection during release to HUAWEI AppGallery.
