Android studio 在android Studio中显示模糊android库（AAR）的API源

我目前正在从事一个android库项目，其软件包层次结构如下：

com.example
    |_______ api (contains the public interface of the library)
    |_______ internal (contains the remaining internal classes)

不幸的是，我需要混淆内部类。这将生成以下proguard-rules.pro文件：

# preserve the line number information for stack traces and android studio integration
-keepattributes SourceFile,LineNumberTable

# hide the original source file name. (<--- This messes up android-studio integration)
-renamesourcefileattribute SourceFile

# Preserve information about throwing exceptions and deprecation of methods
-keepattributes Exceptions, Deprecated, Signature

# Preserve the original parameter names of kept methods
-keepparameternames

# Keeps the names of all public/protected classes/fields/methods in the api package
-keep public class com.example.api.* {
  public protected *;
}

#为堆栈跟踪和android studio集成保留行号信息
-keepattributes源文件，LineNumberTable
#隐藏原始源文件名。(
