Setup for connecting Android Emulatir with live reload to local host PC

How to create a configuration to run with $ ionic cordova emulate android -l -c local and let the emulator connect to host PC, accessing through 10.0.2.2 instead if localhost.

1 angular.json

Create the file environment.local.emulator.ts. Then appli these changes to angular.json.

1. Add this snippet under project.app.architect.build.configurations:

   "local-emulator": {
     "fileReplacements": [
       {
         "replace": "src/environments/environment.ts",
         "with": "src/environments/environment.local.emulator.ts"
       }
     ]
   },

2. Add this under project.app.architect.serve.configurations:

   "local-emulator": {
     "browserTarget": "app:build:local-emulator"
   },

3. Add this under project.app.architect.ionic-cordova-build.configurations:

   "local": {
     "browserTarget": "app:build:local-emulator"
   }

4. Add this under project.app.architect.ionic-cordova-serve.configurations:

   "local": {
     "cordovaBuildTarget": "app:ionic-cordova-build:local",
     "devServerTarget": "app:serve:local-emulator"
   },

2 config.xml

Enable connections to host PC through 10.0.2.2.

1. Add this to config.xml:

   <resource-file src="resources/android/xml/network_security_config.xml" target="app/src/main/res/xml/network_security_config.xml" />

2 Add this to resources/android/xml/network_security_config.xml (or create it if it does not exist):

```xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
        <domain includeSubdomains="true">10.0.2.2</domain>  <!-- Add this line to enable connecting to host PC -->
    </domain-config>
</network-security-config>

```
