我已將 angular 網站轉換為 ionic 也生成了正確的構建，但是在設備中的 APK 之后我嘗試了以下解決方案但對我沒有任何效果-

1.添加到config.xml

2.降級webview插件版本

3.從 index.html 中刪除 href 沒有一個解決方案對我有用，有人幫助解決它嗎？

任何人都可以幫我解決它嗎？

Answer 1

終於問題解決了

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

2.將angular.json文件中的outputPath“dist/angular-ionic”更改為“www”，設置文件夾為www構建離子項目。
