Connecting public IP from angular but not from cordova

Question

I have an Angular application, with an API, that connects and makes calls to a database established in a server with a public IP.

When I create the Angular project with ng serve everything works fine, I can do the calls, the server receives the requests etc Then I wanted to export it to an apk using cordova. When I exuecute ng build --prod --aot ;; cordova build browser ;; cordova run browser --port=3000 everything works fine too. I was able to create the app and everything works fine.

My problem starts when I want to use it in a real device or an emulator. The app is created and you can enter but the calls to the server don't work anymore. I use ng build --prod --aot ;; cordova build android ;; cordova run android --port=3000

So I have to questions:

first, how could I debug this?

Second, do you have any ideas why this could happen?

Thank you

Nothing, I have a login that needs to make a get to the database and it won't just login. But I'll try to search for cors errors. But maybe there are errors, I just don't know how to debug on an Android device — david gonzález-venegas, Mar 02 '20 at 07:59

Documentaion: 'The ng build command with the --prod meta-flag (ng build --prod) compiles with AOT by default.'

On the topic of your problem, I assume that you have forgotten to set the base href tag to be './' instead of '/'. Try this out:

ng build --prod --base-href . ;; cordova run android

Solved, I needed to allow access in the html like:

responseContext.getHeaders().add( "Access-Control-Allow-Origin", "*");
