我的应用不会更新.它构建并运行，但它是一些旧版本，我所做的更改不计算在内.例如，如果我制作 Toast，它就不会显示.如果我删除现有的，它仍然会显示.

推荐答案

我在使用 AndroidStudio Canary 2020.3.1 Canary 2 时遇到了类似的问题.

I had a similar problem with AndroidStudio Canary 2020.3.1 Canary 2.

就我而言，它有助于检查运行/调试配置/始终使用包管理器安装.

In my case it helped to check Run/Debug Configurations/Always install with package manager.

(不过，我可能忽略了这种行为的一些简单原因.)
