Question

[不再有用]

我刚从 Canary chanel 更新到最新版本的 Android Studio，我遇到了这个错误（见下文）。

我刚打开新的Android Studio，点击我的项目，等着看报错。弹出

Gradle sync in progress

仍然存在，但它没有做任何事情。所有项目都是 'broken' ：它没有找到对任何内容的引用。

我是 mac Mac OS X 10.10.2

Answer 1

尝试使用独立版本，这样您就可以随时返回工作设置 (download link)。另外，备份您的 Studio 首选项（以防万一）。

此外，尝试执行 Invalidate caches/Restart 看看是否可以解决问题。

Answer 2

好的，我终于找到了解决办法：

创建一个新项目并且copy/paste源从旧项目到新项目。

就这些了。
