android - 未捕获的翻译 SimException : dx. rop.cst.CstInterfaceMethodRef 无法转换为 com.android.dx.rop.cst.CstMethodRef (Proguard)

Question

我的团队和我一直在努力解决我们在进入 Beta 版之前尝试混淆我们的 Android 应用程序时遇到的异常。

我们得到的异常是:

Error:Uncaught translation error: com.android.dx.cf.code.SimException: com.android.dx.rop.cst.CstInterfaceMethodRef cannot be cast to com.android.dx.rop.cst.CstMethodRef
Possible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

我们正在尝试追踪在 Proguarding 期间发生此错误的位置，但不是非常熟悉 Proguard 以了解如何找到发生故障的位置。

有什么办法可以看出这个翻译错误发生在哪里？如果我知道强制转换异常在我的代码中是什么/在哪里，也许我可以修复它。网上有引用资料指出 Google Play 服务可能会导致其他 sdk 出现问题，但我们已经使用了依赖工具，发现它在所有 sdk 中都正确链接到 8.4.0。

我们的应用程序还使用了 multiDexEnabled true 标志。

这是我们的 proguard 文件:

如果您需要任何更多信息，请告诉我，我很乐意提供，目前这阻碍了我们发布测试版的能力。

Answer 1

所以对我们来说，解决方案似乎是删除:

-keep class * {
    public void *(android.view.View);
}

来自 Proguard，因为在将其与各种库一起使用时肯定存在一些冲突。我希望这能帮助其他遇到这个问题的人，因为我们在这个问题上被困了 6 天。

应该注意的是，您随后应该明确添加对点击处理程序的引用或至少缩小范围，请在此处查看此规则的来源:Android Proguard - how to keep onClick handlers only referenced from XML layouts
