Ionic cordova build android 卡在启动画面

Question

所以我的应用程序在网络上正常运行，现在我想构建 android apk 文件并对其进行测试，所以我这样做了：

ionic cordova platform add android
ionic cordova build android

在这两个之后我没有错误。

然后我去android studio并运行android项目，构建成功。 启动我的应用程序后，我看到离子闪屏只旋转了 1 秒钟，然后他停止了，就是这样。卡在启动画面。

控制台错误：

Answer 1

打开 Chrome 并转到 chrome://inspect/#devices

然后检查您的远程设备并检查控制台选项卡。您可能会遇到插件问题。

你也可以运行

ionic cordova run android -c

这样你可以在你的命令上检查控制台。
