运行不起来是什么原因

[ikidou]

你是用的 Android Studio 还是 IntelliJ idea?，如果是Android Studio，那你先用 Build Project，然后再运行(对于普通Java项目Android Studio 缺少支持，没有编译就运行了)，如果是 idea的话可以通过设置， File -> Setttings -> Build,Execution,Deployment -> Gradle -> Runner -> Delegate IDE build/run action to gradle.这样的话编译会交给Gradle来做，而不是默认编译器，就没这个问题了

我用AndroidStudio，解决了，确实是没有编译造成的，感谢回复。
