启用Proguard时出现错误

Question

我已经在根目录中使用了我的自定义Proguard文件。

文件名：

cus-proguard-android.txt

我刚刚从默认文件中复制了：

我想你忘记了最重要的事情：你遇到了哪个错误？ - guipivoto

@GuilhermeP - 最重要的是什么？我已经发布了错误日志。 - Rahul

错误日志 :) 现在，您已添加。 - guipivoto

@GuilhermeP - 哦，是的，请帮我找到一个解决方案吗？ - Rahul

Proguard生成的警告并不特殊 - 我从未见过没有警告的Proguard运行 - 因此只需添加Proguard dontwarn标志即可... - Robert

Answer 1

你的错误日志似乎没有包含所有警告。

要删除注释信息，您需要添加以下内容：

-dontnote okhttp3.**, okio.**, retrofit2.**, pl.droidsonroids.**

在此之后，可能会有更多需要处理的警告信息。 要完全忽略这些警告并继续处理，请将以下内容添加到您的配置中：

-ignorewarnings

这不就是隐藏一些以后可能有用的信息吗？ - aleksandrbel

为什么你想要为Proguard设置规则，是否默认配置给你带来了任何错误？无论如何，请查看这些链接以获取有关Proguard的详细信息。

默认配置意味着你只需要放置以下行：

minifyEnabled true
useProguard true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 

这些代码行使用默认的Proguard规则。

Dexguard（Proguard的商业版本）

如果想要让代码更加安全，可以使用Dexguard。Dexguard是Proguard的商业版本，因为它具有字符串加密功能，可以使代码更加安全。
