Configuring Obfuscation Scripts

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

1. Open the app-level obfuscation configuration file proguard-rules.pro 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.hianalytics.**{*;}
   -keep class com.huawei.updatesdk.**{*;}
   -keep class com.huawei.hms.**{*;}

2. If you are using AndResGuard, add its trustlist to the app-level build.gradle file of your project. If you do not use AndResGuard, skip this step.

   whiteList = [
       "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 being set to true in the project-level build.gradle file) and strict reference checks (with shrinkMode being set to strict in the res/raw/keep.xml file). Not keeping layout resources will lead to app rejection during release to HUAWEI AppGallery.

       tools:keep="@layout/hms_download_progress,@drawable/screen_off,@layout/upsdk*"
       tools:shrinkMode="strict" />
