Ionic 1 http post failing - ionic-framework

Question

I am compiling an Ionic version 1 App to a device.
When I run ionic serve on the browser I can search and get a search result as the return.
I am using an http.post:
$http.post("http://www.example.com/myapi/mysearch.php", $scope.formData )
.success( function(data) {
After installing on the smartphone all I got is an error message (error).
I think this can be a lack of the whitelist cordova plugin, which I do remove and reinstall again.
Also have added:
<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">
To the index.html file.
How can I enable the apk to make post requests to the API?
Debugging from the real device using Chrome tools return this error message:
Failed to load http://www.myexample.com/api/myexampleapi.php:
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.

Answer 1

To prevent this, you can use Cordova http plugin. It is the native way to make http calls (Cordova http plugin). Also you can check the same issue in the ionic 3 version in this answer
