【中文标题】如何使用 proguard 获取发布构建 apk 文件【英文标题】：How to get release build apk file using proguard 【发布时间】：2016-06-03 01:43:24 【问题描述】：

我正在尝试使用 ProGuard 为我的项目制作发布 apk 文件，显然我正在使用许多第三方库，我只需要使用它们中的几个类，我真的很想得到一些关于这个的解释.

我的调试版本超过20-MB，所以我想通过使用shrinking 中的shrinking 来减少它，但它给了我一些我无法弄清楚的警告，尽管@ 987654322@，不知道应该改什么，

buildTypes 
    release 
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

上面一行显示了build.gradle在module:app中的sn-p

-keepattributes InnerClasses

这是我用来抑制 proguard-rules.pro 中的一些警告的方法，我确实在 Proguard 上查看了其他问题，但无法得到它。我已经提到了我在尝试发布版本时收到的消息

Note: there were 14 classes trying to access generic signatures using reflection.
      You should consider keeping the signature attributes

Note: there were 66 unkept descriptor classes in kept class members.

      (using '-keep').

      You should check if you need to specify additional program jars.

Note: there were 4 accesses to class members by means of introspection.
      You should consider explicitly keeping the mentioned class members

Warning:there were 13 unresolved references to classes or interfaces.
         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.

【问题讨论】：

嗨@pankaj，我好久没用安卓了，抱歉，帮不了你。 @CasparHarmer，好的，我明白了，谢谢 【参考方案1】：

添加这个：

-dontwarn com.squareup.okhttp.**

到你的 proguard-rules.pro

【讨论】：

亲爱的你是我的救命稻草。在谷歌上搜索了很多，但没有一个解决方案有效，但这一行解决了所有警告。只是一个疑问，实际上是因为 okhttp，除了 okhttp 警告之外，为什么日志还打印“注意：配置引用未知类 'com.google.vending.licensing.ILicensingService'”？我的情况也是如此。【参考方案2】：

您必须为每个库编写 pro-guard 规则，否则 pro-guard 会混淆它

这适用于 Admob

 -keep public class com.google.ads.**
       public *;

这是 V7 支持库

-dontwarn android.support.v7.**
-keep class android.support.v7.**  *; 
-keep interface android.support.v7.**  *;

【讨论】：

你能告诉我如何“mapping.txt”和proguard生成的堆栈跟踪你的意思是如何使用？

以上是关于如何使用 proguard 获取发布构建 apk 文件的主要内容，如果未能解决你的问题，请参考以下文章

Proguard 在构建发布 apk 时导致错误

用于 Android Proguard 混淆的 ANT 构建

升级 gradle 后 Proguard 行为发生变化，从构建的 apk 中省略类

proguard applymapping - mapping.txt 的更改不适用于下一个构建签名的 apk

Ant 似乎在打包 apk 时忽略了 Proguard 生成的 jar

使用 Joda Time 时无法生成启用 proguard 的签名 APK
