OneSignal for Android in NativeScript. Wont load library

I'm trying to implement OneSignal Push Notifications in my NativeScript application for both Android and iOS. For iOS I got it working just fine with CocoaPods. However, when I am trying to compile the OneSignal package for Android, I cant get access to the com.onesignal.

So first off, I've added this to my App_Resources/Android/App.gradle:

dependencies {
    compile 'com.onesignal:OneSignal:3.+@aar'
    compile 'com.google.android.gms:play-services-gcm:+'
    compile "com.google.android.gms:play-services-location:+"
}

android {  
  defaultConfig {  
    generatedDensities = []  
    applicationId = "<HIDDEN>"  
    multiDexEnabled true
    manifestPlaceholders = [manifestApplicationId: "<HIDDEN>", onesignal_app_id: "<HIDDEN>", onesignal_google_project_number: "<HIDDEN>"]
  }  
  aaptOptions {  
    additionalParameters "--no-version-vectors"  
  }  
}

I've the run the command tns build android This gives me this line: :prepareComOnesignalOneSignal311Library UP-TO-DATE

My app.js looks like this:

var application = require("application");

application.on(application.launchEvent, function (args) {
    if (args.android) {
        console.dump(com.onesignal.OneSignal);
    } 
});

// iOS specific configuration
if (application.ios) {

    var __extends = this.__extends || function (d, b) {
        for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];
        function __() { this.constructor = d; }
        __.prototype = b.prototype;
        d.prototype = new __();
    };

    var appDelegate = (function (_super) {
       __extends(appDelegate, _super);
       function appDelegate() {
           _super.apply(this, arguments);
       }

       appDelegate.prototype.applicationDidFinishLaunchingWithOptions = function (application, launchOptions) {
            OneSignal.initWithLaunchOptionsAppId(launchOptions, '<HIDDEN>');
            //console.dump(OneSignal);
            OneSignal.sendTagValue('route', 599);
       };

       appDelegate.ObjCProtocols = [UIApplicationDelegate];
       return appDelegate;

    })(UIResponder);

   application.ios.delegate = appDelegate;

}

application.start({ moduleName: "main-page" });

When running the app the emulator just gives me a white screen with the following, telling me that com.onesignal is null:

Unhandled Exception
java.lang.RuntimeException: Unable to start activity ComponentInfo{no.trv.tommeplan/com.tns.NativeScriptActivity}: com.tns.NativeScriptException: 
Calling js method onCreate failed

TypeError: Cannot read property ‘OneSignal’ of undefined
File: «/data/data/no.trv.tommeplan/files/app/app.js, line: 5, column:31...

So basically, when dumping com the object only contains com.android, com.app and com.tns. So onesignal isn't imported it seems like. Now, Im stuck. Anyone got any ideas?

Looks like you've done everything correctly. However, my guess is that you forgot something a lot of people overlook :) If you have built & ran this .apk on the device/emulator prior to adding the lib in app.gradle there is a chance you aren't actually getting the updated .apk on the device/emulator. I don't know why this happens on Android, it's some sort of caching I suppose, never looked into it too much.

So what you need to do is outlined here: https://bradmartin.net/2016/07/20/ahhh-this-nativescript-plugin-doesnt-work/ and I'll also list the steps here.

  1. Uninstall the .apk from the device/emulator
  2. Execute tns build android to get a fresh .apk (just to be certain)
  3. Execute tns run android or tns livesync android which will install the updated .apk on the device/emulator.
  4. Get a beer (hopefully).

Seriously, that should resolve the issue if indeed the library is installing correctly.
