java - 无法导入库 libcore.io.IoBridge

Question

我正在尝试在 Android Studio 2.0 中运行一个开源项目。我的问题是我无法导入类 IoBridge (import libcore.io.IoBridge;)。编译器说 libcore 不存在。实际上在我的 SDK(修订版 23)中没有名为 libcore 的库。下面是代码。

Answer 1

显然，该代码旨在构建为系统固件的一部分，而不是来自 Android SDK 应用。 libcore 不适用于 Android SDK 应用程序开发人员。

具体来说，根据屏幕截图，您似乎试图从 Android 开源项目编译 java.net.Socket，该项目并非设计为作为 Android 应用程序的一部分进行编译。
