多个新的 Proguard 在 Multidex 项目中发布 Google Play 服务 v10.2.6 到 v11.0.0

Question

我更新了我们的应用以使用最新的 Android Firebase SDK v11.0.0 (https://firebase.google.com/support/release-notes/android#20170607)，突然出现了一堆新的 proguard 错误，仅供参考，之前使用 proguard 一切正常。

之前：

compile 'com.google.firebase:firebase-messaging:10.2.6'
compile 'com.google.android.gms:play-services-vision:10.2.6'

之后：

compile 'com.google.firebase:firebase-messaging:11.0.0'
compile 'com.google.android.gms:play-services-vision:11.0.0'

问题在于它似乎不是一个简单的新缺少的 proguard 条目，但它似乎破坏了整个事情，突然之间其他几个库似乎受到了这种变化的影响。

这些是与 GMS 相关的 Proguard 问题：

您可能需要检查此Proguard Troubleshooting manual，其中指出对于遇到的警告，the configuration keeps the entry point...but not the descriptor class：

您的配置包含一个-keep 选项来保留给定的方法（或字段），但没有-keep 选项用于给定类，该类是方法描述符中的参数类型或返回类型。然后，您可能也想保留课程。否则，ProGuard 将混淆其名称，从而更改方法的签名。然后，该方法可能会成为无法找到的入口点。您可以使用-keep 选项修饰符includedescriptorclasses (-keep,includedescriptorclasses ...) 自动保留此类描述符类。您可以通过指定-dontnote 选项来关闭这些注释。

要获得更多见解，这些 SO 帖子也可能会有所帮助：

• Proguard: can't find referenced class
• Proguard unresolved references to classes

总而言之，您可能想尝试将这两行添加到您的 Proguard 配置文件中：

-keep class com.google.android.gms.**
-dontwarn com.google.android.gms.**

Android Firebase SDK v11.0.0 似乎注定要失败，Android Firebase SDK v11.0.1 修复了它，没有任何额外的改变.
