我如何解决这个问题？

我添加以下代码在project.properties和proguard的-project.txt

project.properties

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 

proguard的-project.txt

-injars lib 
-optimizationpasses 5 
-dontusemixedcaseclassnames 
-dontskipnonpubliclibraryclasses 
-dontpreverify 
-dontnote 
-verbose 
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

#Keep the R 
-keepclassmembers class **.R$* {

}

构建过程允许工具aapt写出配置文件proguard.txt，然后将其传递给ProGuard。但是，当前版本的aapt有一个错误 - 如果我没有记错，它不会处理带有引用字符串定义的类名的XML文件（位于res/values/strings.xml）。目前，你应该避免这样的字符串定义。

请注意，文件proguard-project.txt本质上应该是空的，因为大部分配置已在共享配置文件${sdk.dir}/tools/proguard/proguard-android.txt中指定。构建过程还会自动为您指定所有-injars，-outjars和-libraryjars。
