android - 可以构建Android Project(Cmd F9)，但由于GSON BEGIN_OBJECT BEGIN_ARRAY问题而导致运行(Ctrl R)错误

我昨天迁移到Android Studio 4.0，因为我想开始使用Jetpack Compose。升级Gradle和其他一些东西以使构建实际可用后，我能够成功构建(Cmd F9)项目(没有错误)。

但是，当我尝试运行(Ctrl R)项目时，它会在构建过程中使用所有绿色成功指示符运行(加上一些有关函数中未使用变量的警告)，然后出错。是什么原因造成的？

除了在我的build.gradle中添加依赖项之外，我不知道如何使用Gradle进行任何操作，或者不遵循Google之类的网站的直接指示，即必须升级AS才能使用Jetpack Compose。因此，我不知道如何在构建过程中放置​​断点以查看正在发生的事情(搜索表明这实际上是不可能的)或如何找到问题所在。似乎Gradle期望有某种东西是JSON {}，但是却找到了JSON []。但是错误肯定不会暗示它可能是什么。

最佳答案

使用Android Studio的预发布版本可能会不时引起问题，特别是对于现有项目。总体而言，我尝试仅将预发布Studio版本与在这些版本中创建的项目一起使用，而不与现有项目一起使用。

但是，基于this issue，清理和重建项目应该可以解决此问题...并且基于your comment，显然可以。

我的解释:现有项目构建文件中的某些内容(例如.idea/中)具有指向JSON文档的URL，并且该文档的结构已更改。清理项目会将其切换到新的URL，指向结构与预发行版Android Gradle Plugin期望匹配的文档。

关于android - 可以构建Android Project(Cmd F9)，但由于GSON BEGIN_OBJECT BEGIN_ARRAY问题而导致运行(Ctrl R)错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60252509/
