我已将 Angular 网站正确转换为 ionic 也生成了构建，但在 APK 之后 在我尝试过以下解决方案的设备中，但对我没有任何效果-

1.添加到config.xml

2.降级webview插件版本

3.从 index.html 中删除 href 没有一个解决方案对我有用，有人帮忙解决一下吗？

谁能帮我解决一下？

Answer 1

问题终于解决了

1. Change <base href=”/”> into <base href=”./”> in the index.html file.

2.将angular.json文件中的outputPath“dist/angular-ionic”更改为“www”，设置文件夹为www构建Ionic项目。
