Adding and using plugins on Ionic - angularjs

Question

Please, I need a final step-by-step to add and use plugins with Ionic.
I lost several weeks trying to use plugins on Ionic but everytime I got plugin function "is not defined". I really need to solve this issue, but I don't got success.
First of all I'm not trying to use native plugins that uses special hardware components like camera. I'm following the steps below:
1) I created my app using cordova
2) I added my plugin using:
cordova plugin add mercadopago-plugin
3) I've inserted this following scripts on my index.html:
<script src="cordova.js"></script>
<script src="app.js"></script>
4) I created a button calling my plugin on my template.html
<button ng-click="startCheckout()"> OK </button>
5) I called my plugin on app.js
.controller('MyCtrl', function($scope) {
$scope.carrinho = allcarrinho;
var publicKey = "TEST";
$scope.startCheckout = function(){
MercadoPago.startCheckout(publicKey, prefId, null, false, success, failure);
}
})
6) I've emulated my app on the browser typing on my admin prompt command:
ionic serve
But when the plugin is called I got this error:
ReferenceError: MercadoPago is not defined
I following everything on documentation:
Plugin's documentation: http://mercadopago.github.io/px-hybrid/
How do I to fix it?
Thanks!

Answer 1

You probably have to inject MercadoPago in your controller:
.controller('MyCtrl', function($scope, MercadoPago /*<--here*/) {
I didn't see your full code but it has to be something like that.
or to have it not break when minifying:
.controller('MyCtrl', ['$scope', 'MercadoPago', function($scope, MercadoPago) { ....
See this

Answer 2

Most Cordova plugins do not work in the browser. You should try on an emulator or simulator.
Either that, or you need to wait for document.ready or ionicPlatform.ready for the plugin to initialize before trying to use it

Answer 3

This plugin makes native calls when you use ˝MercadoPago". It won't work in your browser, you should run it on an Android Emulator or Phone.
Try:
ionic emulate android -l -c
And it should work.
