android Jetpack 入门项目不能运行
android jetpack getting started project cant run
我是 android 开发的新手，刚刚按照本教程在 android studio 3.2 ( canary ) 中创建了我的第一个 "hello world" 项目。 https://developer.android.com/jetpack/docs/getting-started
然后我只是做了 Build-> make project project tryed to build 并给了我以下错误。
Could not get unknown property 'archLifecycleVersion' for root project 'JetpackHelloWorld' of type org.gradle.api.Project.
但我能够在我发布的问题的答案的帮助下解决该错误。
在解决该错误后，我尝试再次构建，但现在出现以下错误。
the '-d' option with a directory destination is ignored because '-Xbuild-file' is specified
运行 已禁用
如您在屏幕截图中所见，应用程序的 运行 选项被禁用，如果我单击下拉菜单，它会要求我编辑配置，我应该在空项目？
but then I clicked on Edit Configurations and added a android application configuration, but at the point of selecting modules there was no modules in drop down list to select from, and now I cant run my app because i get the error "confuguration is not valid" I also see a red cross icon on my app name near the run button, I think that is because I have not selected a module? but how can I select one when there isnt any?
试着点击右边那个火箭东西右边两个按钮（Gradle 同步），看看是否有帮助
