I’m no expert.  
Sorry if the question is insignificant, but as I’m learning to ask.

How to use native ionic 2, in the following situation:  
How to print in html(AppVersion.getVersionCode();)?  
What is the process to get the result? Will the constructor? Could you give me a simple example of use? The way that the documentation I could not understand.

in .js  
import {AppVersion} from ‘ionic-native’;

AppVersion.getAppName();  
AppVersion.getPackageName();  
AppVersion.getVersionCode();  
AppVersion.getVersionNumber();

in .html  
`<ion-card-content> {{VERSAO}} </ion-card-content>`

I have already installed the plugin in my project.  
$ ionic plugin add cordova-plugin-app-version

I think all those functions return a promise rather than a value. Try something like this in your constructor:

```
this.versionNumber = 'unknown';

if(this.platform.is('cordova')) {
    AppVersion.getVersionNumber().then((s) => {
    this.versionNumber = s;
  })
} 

```

and then use

```
{{versionNumber}}

```

in your html template.

The “[platform.is](http://platform.is)” wrapper is to avoid errors if you’re testing in a browser.

Might be a scope problem, are you sure “this” is referring to the correct namespace?
