ProGuard 番石榴配置，具有模糊处理和优化功能

从番石榴17.0开始，这是我在ProGuard配置中需要的：

-dontwarn javax.annotation.**
-dontwarn javax.inject.**
-dontwarn sun.misc.Unsafe

否则，生成将失败，并显示以下警告：

Warning: com.google.common.base.Absent: 
   can't find referenced class javax.annotation.Nullable

（这是因为Guava使用的注释不属于Android运行时（android.jar）。在这种情况下，只需将警告静音即可。

如果您使用Gradle作为构建工具，则上述和以下内容会在使用番石榴时生成经过优化和混淆的APK。proguard-project.txtbuild.gradle

buildTypes {
    release {
        minifyEnabled true
        proguardFile file('proguard-project.txt')
        proguardFile getDefaultProguardFile('proguard-android-optimize.txt')
    }
}

或者，您可以在依赖项中包含对 jsr305.jar 的依赖关系：build.gradle

compile 'com.google.code.findbugs:jsr305:2.0.2'

...仅在ProGuard配置中，但我更喜欢也用于这些东西。-dontwarn sun.misc.Unsafe-dontwarnjavax

从23.4-android升级到23.5-android时，我必须将以下行添加到我的proguard规则文件中：

-dontwarn afu.org.checkerframework.**
-dontwarn org.checkerframework.**

下面列出了我从更新中看到的 proguard 警告（在添加新规则之前），以供参考：
