NativeScript +Angular 2 + 3rd party Java Libraries

Question

Today I started learning nativescript. I am trying to build simple ng2 app which would use 3rd party java library. I am trying to achieve something like in here

http://developer.telerik.com/featured/using-native-libraries-in-nativescript/

but I keep getting undefined errors.

I have no problem of accessing java within my ts code:

import app = require("application");
import platform = require("platform");
declare var java;
.......
public get message(): string {
        var str = new java.lang.String('Hello world!');
        var result = str.endsWith('world!');
        console.log(result); // true

But I can't access 3rd party java library

import {Component} from "@angular/core";
import app = require("application");
declare var KontaktSDK;

@Component({
    selector: "my-app",
    templateUrl: "app.component.html",
})
export class AppComponent {
    public counter: number = 16;

    public onTap(args) {
        KontaktSDK.initialize("API_KEY");
        this.counter--;
    }
}

It throws reference error "KontaktSDK is not defined"

Thank you for your help!

When accessing android native methods in nativescript you need to use the full package name and class e.g com.kontakt.sdk.android.common.KontaktSDK.initialize("API_KEY") also a little trick i picked up while developing nativescript plugins is you can use console.dump(com.kontakt.sdk.android.common.KontaktSDK) on a class and it would display all methods contained in that class . When in doubt log it out
