Gradle 3.0.0 的 Proguard 问题

【问题描述】：

我正在尝试使用 ProGuard 和新的 Gradle 3.0.0 版本创建一个 APK。我收到了很多关于我认为我在 ProGuard 配置文件中忽略的类的警告。相同的配置适用于 Gradle 2.3.3，但似乎在 3.0.0 上中断。警告太多了，几乎根本没有读取 ProGuard 配置。

我的 build.gradle

【问题讨论】：

你必须自己在proguard-rules.pro写proguard规则。

我也有同样的问题。由于某种原因，apk 包含来自 android.jar 的所有类以及存根方法。如果我将-dontwarn android.** 添加到我的proguard-rules.pro 文件中，则会构建apk。当我运行它时，我得到java.lang.RuntimeException: Stub! at android.content.g.<init>(Unknown Source) ...。

我也有同样的问题。 APK 在 2.3.3 上成功构建。有更新吗？

我也有同样的问题，请问有更新吗？

在运行发布版本时遇到同样的情况，有没有人找到解决方案？似乎 proguard 根本没有被执行。或者可能是结构的变化？

【参考方案1】：

我已经升级到 gradle 3.0.1 并且大部分警告都消失了。如果您仍在使用 3.0.0，请在您的 proguard 文件中使用它

-dontwarn android.**

不理想，但可以正常工作。

【参考方案2】：

我遇到了同样的问题，虽然我的情况有点独特，但这是我的解决方案：

升级到新的 3.0.1 版本 (com.android.tools.build:gradle:3.0.1) 后，我看到的警告变少了（最初我有 >3000 个警告）。 我的问题的根源是我使用了一个依赖于整个android框架的库（这个：https://github.com/tony19/logback-android，问题#73）。

我还查看了依赖项 (./gradlew app:dependenices)，因为我有依赖于旧 apache http 客户端的库，这也会导致一些警告。我也必须消除它们。

【参考方案3】：

它可以帮助你 Enabling ProGuard for local library modules no longer affects the library's code. Instead, you should run ProGuard on the app module that consumes the library. https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

【讨论】：

您能否至少通过一个示例来详细说明您的答案？几乎没有网址的答案是没有用的。
