我是javaScript的新手,React-Native尝试创建演示应用程序。应用程序在模拟器中正常运行。以下是相同的截图: Emulator Screenshot
如果我尝试在我的设备上运行应用程序,则应用程序不会运行。以下是相同的截图:
如果需要发布任何代码,请告诉我。我试图寻找上述问题的解决方案,但无法找到任何
以下是JavaScript代码:

好的我只是从那篇文章中复制它:)
将JS文件捆绑到您的apk中,同时让您的服务器运行(react-native start)将捆绑包下载到您应用的资源目录中:

我还遇到了与启动localhost服务器http-server -c-1解决它的问题相同而不是运行此命令 &#39; adb reverse tcp:8081 tcp:8081&#39;之后运行react-native run-android
