Question

我刚从Canary chanel更新到最新版本的Android Studio，我有这个错误（见下文）。

我只需打开新的Android Studio，点击我的项目并等待查看错误。弹出窗口

正在进行Gradle同步

仍然存在，但它没有做任何事情。并且所有项目都“被打破”：它没有找到任何参考。

我是mac Mac OS X 10.10.2

Answer 1

尝试使用独立版，以便您可以随时返回工作设置（download link）。另外，备份您的Studio偏好设置（仅我的情况）。

此外，请尝试执行Invalidate caches/Restart并查看是否可以解决此问题。

Answer 2

好的，我终于找到了解决方案：

创建新项目并将源从旧项目复制/粘贴到新项目。

就是这样。
