Android livereload not working

Description of the problem: ionic capacitor run android --livereload launches Android Studio as expected, and it shows up in the emulator when you run in.

However, when you change the web source, for example home.page.html, you can observe that Angular compiles but the app is not updated in the emulator.

[ng] ℹ ｢wdm｣: Compiling...
[ng] Date: 2019-07-26T11:41:55.215Z - Hash: f7a5c98bae47fab75e0d - Time: 844ms
[ng] 103 unchanged chunks
[ng] chunk {home-home-module} home-home-module.js, home-home-module.js.map (home-home-module) 4.92 kB  [rendered]
[ng] ℹ ｢wdm｣: Compiled successfully.

I verified by opening a browser and going to http://localhost:8100 that the source has indeed updated, but it is just not reflected in the Android emulator.

What makes it even stranger is that if I open chrome and inspect (chrome://inspect/#devices) and force a reload that way, I can see that the Android emulator reloads, but the changes are not reflected. Maybe some sort of Capacitor webview caching issue?

Here’s steps to reproduce:

1. git clone https://github.com/biesbjerg/capacitor-android-livereload.git
2. ionic capacitor run android --livereload
3. Run in emulator when Android Studio has launched
4. Make a change to web source

The problem is that command is setting the server url to localhost, and that makes to load the local assets.

If you run with ionic capacitor run android -l --address=0.0.0.0 then it will work.

I think Ionic CLI is going to be updated to add the --address=0.0.0.0 as default when the run is targeted to android.

Keeping it open because in #1776 we are trying to workaround this problem too, but have in mind that localhost as live reload server url won’t work on real devices unless you enable port forwarding in chrome inspector.
