Ionic CLI - ionic capacitor run android

Hello,

One of the ionic cli commands needs a bit of tweaking. `ionic capacitor run android -l` runs by default `ng run app:serve --host=localhost --port=8100` with the server being localhost and port 8100, then it does a `capacitor copy android` and opens the android studio.

When we launch the android emulator, it is watching for changes on localhost:8100, however localhost:8100 is not reachable from the device emulator, the host machine is at 10.0.2.2 (https://developer.android.com/studio/run/emulator-networking).

It seems like we either need a rule to forward localhost to 10.0.2.2 or to let the android studio / emulator handles their own stuff, we can offer 2 urls in capacitor.config.json one url for the angular serve (localhost:8100) and one for the android emulator (10.0.2.2:8100).

Thoughts?

從入口點 `ionic capacitor run android -l` 開始，追蹤此處所述的 `ng run app:serve --host=localhost --port=8100`、`capacitor copy android` 和 Android Studio 流程。閱讀 `capacitor.config.json` 和 Android 模擬器網路連線指南；當 Live Reload 能夠到達模擬器，且不會破壞現有的瀏覽器或 Android 工作流程時，即表示完成。
