  1. Rua via localhost:8000 or run emulate/device that`s best practice.
  2. Look connection firebase too.
  3. Page origem access allow get data.

The only thing not working is a few pages who request to url to get some json data, is getting the error from no allowed request from origin localhost:8080 but i have defined everything in config.xml based on documentation

Look your virtual machine network because Android works.
Try work on Android on virtual machine.

Look the effect!

The problem is not your app. Not config.xml.

The problem is CORS. On iOS, Ionic uses CDVWebkitWebview, which uses the new webview on iOS. That new webview respects CORS settings.

The problem is that the server you are accessing is rejecting the cross-origin request. If you inspect the network requests, you will see an OPTIONS call. That call is getting an error back, so the webview says “Hey, I can’t access that URL.”

There are 2 solutions to this:

  1. Use the native HTTP plugin, which bypasses CORS completely, or
  2. Change the server to allow the network request. If you have control of the server, you can do that. If not, you need to use option #1.
