Firebase init fails on android device

[lowe0292]

I got the demo to work, but when adding this plugin to angular2-seed-advanced I keep getting this error:

JS: Error in firebase.init: TypeError: Cannot read property 'firebase' of undefined
JS: firebase.init error: TypeError: Cannot read property 'firebase' of undefined

Here's my code:

// libs
import {Store} from '@ngrx/store';
// app
import {FormComponent} from '../../frameworks/core.framework/index';
import {NameListService} from '../../frameworks/app.framework/index';
var firebase = require('nativescript-plugin-firebase');
@FormComponent({
  selector: 'sd-home',
  templateUrl: './app/components/home/home.component.html',
  styleUrls: ['./app/components/home/home.component.css']
})
export class HomeComponent {
  public newName: string = '';
  public count: number = 0;
  constructor(private store: Store<any>, public nameListService: NameListService) {
    firebase.init({
      url: 'https://ng2-test-107d1.firebaseio.com/',
      persist: true
    }).then((instance: any) => {
      firebase.query((result: any) => {
        this.count = result.value;
      }, 'nativescript', { singleEvent: true });
    }, function (error: any) {
      console.log("firebase.init error: " + error);
    });
  }
  /*
   * @param newname  any text as input.
   * @returns return false to prevent default form submit behavior to refresh the page.
   */
  addName(): boolean {
    this.nameListService.add(this.newName);
    this.newName = '';
    return false;
  }
  addOne(): void {
    firebase.setValue('/nativescript', this.count++);
  }
}

What am I missing?

Note, I have it working on the iOS emulator, still no luck with my android device (HTC One m8, getting the error above) or the genymotion emulator:

Here's the full codebase: https://github.com/castle-dev/ng2-seed-test

[isaackwan]

I too have encountered this problem. Here is how I solved it:

1. Installpackages Google Play Services and Google Repository in your Android SDK Manager
2. Set the applicationId directive in build.gradle

Hope my 2 cents helped!

[nikolal]

@isaackwan Tnank you, this worked for me.

[lowe0292]

Solved for me too, thanks @isaackwan!

@EddyVerbruggen want me to submit a PR to add this info to the Android Installation section in the README?

[EddyVerbruggen]

Thanks guys! I added that applicationId to my own app/App_Resources/Android/app.gradle file but forgot to add it to the readme.

@lowe0292 I'm adding it to the readme after a few tests, thanks for offering!

[zakdances]

I still don't see it in the readme. Are we suppose to be creating app/App_Resources/Android/app.gradle ourself?

Looks like you need to install/reinstall nativescript-plugin-firebase?
