这实际上不是RxJava错误，也不是翻新.这是即时运行错误，我禁用了它，并启动了我的应用程序.

This is in fact not RxJava error neither Retrofit. It is Instant run error, i disabled it and my app launched.

作为临时解决方案，您也可以禁用即时运行.

As a temporary solution, you can disable Instant run, too.

要执行此操作，请在设置"中转到 Build，Execution，Development -> Instant Run .

To do it, go to Build, Execution, Development -> Instant Run in Settings.
