推荐答案

首先实现 multidex 进入项目，然后重新启动android studio并运行您的应用.
如果仍然遇到此问题，则需要降级android studio's稳定版本3.5.3

First implement multidex into your project then restart android studio and run your app.
If still you face this issue, then you need to downgrade your android studio's stable version 3.5.3

在Android Studio 3.5以下禁用即时运行:

Android Studio --> File --> Setting --> Build, execution, deploy --> Instant run.
