coder 2023-12-25 原文

我用于编译我的 Android 应用程序的 Ant 脚本运行良好，但在将 Google Play 服务库更新到版本 5.0(修订版 18)后，ProGuard 失败并显示以下输出:

将它与以前的(工作)输出进行比较，以下几行是新的:

 [proguard] Note: android.support.v4.app.NotificationCompatJellybean: can't find dynamically referenced class android.app.Notification$Action

在输出的末尾加上错误信息。

发生了什么事？ android.view.accessibility.CaptioningManager 似乎是在 API 级别 19 中引入的。

最佳答案

我注意到Android支持库的目标版本从16变成了19(同时更新到revision 20)。我的应用程序是针对目标版本 17 构建的。所以我将主应用程序项目的目标版本从 17 更改为 19，现在一切正常。就是这样!
