Combining NativeScript with Angular 2 and leveraging third-party Java libraries

Recently, I decided to delve into learning Nativescript. My goal is to create a simple ng2 app that utilizes a third-party Java library, similar to the example provided in this link:

However, I am encountering undefined errors along the way.

While I have no trouble accessing Java within my TypeScript 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

I seem to struggle with accessing the third-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--;
    }
}

An error is thrown stating "ReferenceError: KontaktSDK is not defined".

I would greatly appreciate any assistance you can provide!

When working with android native methods in nativescript, it's important to remember to use the full package name and class. For example, you would call

com.kontakt.sdk.android.common.KontaktSDK.initialize("API_KEY")
. Another helpful tip I discovered while creating nativescript plugins is that you can use
console.dump(com.kontakt.sdk.android.common.KontaktSDK)
on a class to view all the methods it contains. When in doubt, log it out!
