问题描述

在发布模式下，当我启用仅多 dex 时，我的应用程序大小为 33.30MB，相当大.经过一系列的研究，我意识到 PROGUARD 缩小了 apk 的大小.在我的解决方案中启用 proguard，我收到此错误.我的 PROGUARD 解决方案中可能缺少什么(缩小我的应用程序大小)?

In the release mode, when i enable only multi dex, my app size is 33.30MB which is quite large. After series of research, i realized PROGUARD shrinks the apk size. Enabling proguard in my solution, i get this error. What could i be missing in my solution for PROGUARD to work (shrink my app size)?

推荐答案

Proguard 告诉您，您需要先修复警告，然后才能允许它构建.

Proguard is telling you that you need to fix your warnings before it will allow it to build.

   java.io.IOException: Please correct the above warnings first.
        at proguard.Initializer.execute(Unknown Source)
        at proguard.ProGuard.initialize(Unknown Source)
        at proguard.ProGuard.execute(Unknown Source)
        at proguard.ProGuard.main(Unknown Source)

您可以逐一修复所有这些错误(通过使用 -keep)，或者您可以忽略警告.有两种方法可以解决这个问题:

You can either go one-by-one to fix all of these errors(By using -keep), or you can ignore the warnings. There are two ways to go about this:

  1. 使用-ignorewarnings

指定打印有关未解决的引用和其他重要问题的任何警告，但在任何情况下都继续处理.忽视警告可能是危险的.例如，如果确实需要处理未解析的类或类成员，则处理后的代码将无法正常运行.仅当您知道自己在做什么时才使用此选项！

Specifies to print any warnings about unresolved references and other important problems, but to continue processing in any case. Ignoring warnings can be dangerous. For instance, if the unresolved classes or class members are indeed required for processing, the processed code will not function properly. Only use this option if you know what you're doing!

  1. 使用-dontwarn [class_filter]

指定完全不对未解决的引用和其他重要问题发出警告.可选的过滤器是一个正则表达式；ProGuard 不会打印有关名称匹配的类的警告.忽视警告可能是危险的.例如，如果确实需要处理未解析的类或类成员，则处理后的代码将无法正常运行.仅当您知道自己在做什么时才使用此选项！

Specifies not to warn about unresolved references and other important problems at all. The optional filter is a regular expression; ProGuard doesn't print warnings about classes with matching names. Ignoring warnings can be dangerous. For instance, if the unresolved classes or class members are indeed required for processing, the processed code will not function properly. Only use this option if you know what you're doing!

您可以通过我写的文档了解如何创建自定义 proguard 配置:

You can find out how to create a custom proguard configuration via the documentation I wrote:

https://developer.xamarin.com/guides/android/deployment,_testing,_and_metrics/proguard/#Customizing_ProGuard

为什么会收到您可能会问的警告?这很可能是由于链接器在 Proguard 运行之前剥离了这些项目.在这里查看我的笔记:

Why do you get those warnings you may ask? It's most likely due to the Linker stripping these items before Proguard is run. See my notes on this here:

https://developer.xamarin.com/guides/android/deployment,_testing,_and_metrics/proguard/#Linker_Step

这篇关于启用 PROGUARD - Xamarin.Android的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
