android – 使用Proguard构建时的多个警告

概述我真的想在我的应用程序中使用这个Proguard功能,但是看到那千个警告让我想知道它是否值得…我应该添加什么才能使它成功构建？或者让我知道这是否是一个失败的原因…… 这是我的Gradle文件： (……) buildTypes { release { minifyEnabled true shrinkResources true 我真的想在我的应用程序中使用这个Proguard功能,但是看到那千个警告让我想知道它是否值得…我应该添加什么才能使它成功构建？或者让我知道这是否是一个失败的原因……

@H_403_16@解决方法 我通常需要告诉proguard保留第三方库以使其成功构建.例如,ID为Okio和fasterxml添加以下内容：

-keep class okio.** { *; }-dontwarn okio.**-keep class com.fasterxml.** { *; }-dontwarn com.fasterxml.**

为项目中包含的每个第三方库添加上述内容.从你的日志我看到glassfish,jersey,squareup,Google,Okio和fasterxml.

以下是有关上面列出的proguard规则的更多信息：

Using “dontwarn” in proguard

Android Proguard – is it best practice to -keep all 3rd party libs?
