Hi, 各位前輩好,
我正在使用 ionic cordova run android --livereload，想把 ionic cordova project 跑在 android 模擬器裡，方便開發和 debug，但我原本的 project 跑會有問題，Andoird 模擬器總是顯示 Webpage not available and net::ERR_CONNECTION_REFUSED(http://localhost:8100) 。
我下的指令是：
ionic cordova run android --emulator --target=Pixel_6_API_31 --livereload --debug --verbose
我不懂為什麼加上 --no-native-run 也不行？文件說 The Ionic document says --no-native-run: Do not use native-run to run the app; use Cordova instead. 這的確是 cordova project 啊。
ionic cordova run android --no-native-run --target=Pixel_6_API_31 --livereload --debug --verbose
在 Chrome inspect 顯示的 log
重整後有時是這樣
起初我以為是我的 project 有問題，所以我跑 ionic start test20230503 blank --cordova 開一個全新最乾淨的 blank project，就只有一個幾乎空白的首頁，我什麼套件都沒裝，但還是一樣！？？？
我的 config.xml 設定檔：

我的 Package.json，一些 cordova plugins 是 cordova 自己裝的.

我 google 了很多次，有人建議加上以下設定在 config.xml。
<allow-navigation href="http://localhost:8100" />
<allow-navigation href="*" />
<platform name="android">
<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application" xmlns:android="http://schemas.android.com/apk/res/android">
<application android:usesCleartextTraffic="true" />
</edit-config>
</platform>
但都沒用。
事實上這只會在 ionic cordova run android --livereload 發生，Livereload run 在 iOS 完全可以。

Google 很多人也有同樣的問題，但至今我尚未找到一個很精確的解決方式，請問有前輩遇過這樣的問題嗎？請問什麼原因造成的呢？怎麼解呢？萬分感激！
