有人能帮我吗。这个问题有几个原因,也有几个解决方案: 首先要尝试的是使缓存失效并重新启动,通常这只是Android Studio的缓存问题
如果这不起作用,您可能会遇到Gradle/Android Studio版本问题。通常在升级CompileSDK时,gradle版本也需要更新,但Android Studio会抱怨您遇到的错误(我已经遇到过)。同时将您的Android Studio更新至最新稳定版本(我猜这是解决您问题的解决方案)重建项目后,单击“工具”->“Android”->“将项目与渐变文件同步”文件-->无效更改/重新启动在我的案例中有所帮助。此外,清理和重建项目也会有所帮助。我会使缓存失效/重新启动,清理项目,重建但不起作用重新导入您的项目,这对我来说通常是可行的在mac中如何做到这一点?我是否应该将安卓studio从当前版本3.2.1升级到更高版本?是的,当前最新版本是3.3.2如果我没有弄错,我正在升级。我会让你知道它是否有效
