安卓工作室 : UnsupportedOperationException: Operation is not supported > for read-only collection

Question

我使用的是 Android Studio 3.3.2每次我打开我的项目时，都会出现一条消息:由于批量更新，索引暂停。

IDE 捕获了一个错误:

java.lang.UnsupportedOperationException: Operation is not supported for read-only collection

我必须去File>Invalid cache/restart 来解决这个问题。有人知道如何用无效缓存修复它吗？

Answer 1

尝试使用新的 Android Studio 版本重新导入您的项目。

同时尝试使缓存无效并重新启动。

File > Invalidate Cache & Restart > Just Restart

如果此解决方案不起作用，请尝试只按消息右侧的播放按钮。这种事在我身上发生过很多次。
