Implementing Google Analytics in Ionic 5 with Capacitor

Question

I am trying to implement the GA on an ionic project for days now without any luck.

import { Plugins } from '@capacitor/core';
const { GoogleAnalytics } = Plugins;

... 

initializeApp() {
    GoogleAnalytics.startTrackerWithId('G-0000000000')
    .then(() => {
        alert('Google analytics is ready now');
    })
   .catch(e => alert(e));

Answer 1

So basically, first of all, I needed to use google gtag . Neither Cordova nor Capacitor could solve my problem. I used "simple JS include" approach.

index.html

Add tracking code to the header

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
<script>
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());
</script>
<!-- End Google Analytics -->

Create a service for gtag/analytics

./providers/analytics/analytics.service.ts

import { Injectable } from '@angular/core';
declare var gtag;

@Injectable({
  providedIn: 'root'
})
export class AnalyticsService {

  constructor() { }

  startTrackerWithId(id) {
    gtag('config', id);
  }

  trackView(pageUrl: string, screenName: string) {}

  trackEvent(category, action, label?, value?) {}
}

app.module.ts

Add AnalyticsService to the providers

import { AnalyticsService } from './providers/analytics/analytics.service';

@NgModule({
    declarations: [AppComponent, NotificationsComponent],
    imports: [ ... ... ],
    entryComponents: [NotificationsComponent],
    providers: [
      ...
      AnalyticsService,
      ...
   ],
   bootstrap: [AppComponent]
})
export class AppModule {}

app.component.ts

import { AnalyticsService } from './providers/analytics/analytics.service';

export class AppComponent implements OnInit, OnDestroy {

    constructor(
        ...
        private analyticsService: AnalyticsService,
        ...
    ) {
      this.initializeApp();
    }

   ...

    initializeApp() {
         this.analyticsService.startTrackerWithId('G-XXXXXXXXXX');
    }

}

First install the plugin

npm install cordova-plugin-google-analytics
npm install @ionic-native/google-analytics
ionic cap sync

Then

import { GoogleAnalytics } from '@ionic-native/google-analytics/ngx';

constructor(private ga: GoogleAnalytics) { }
this.ga.startTrackerWithId('YOUR_TRACKER_ID')
   .then(() => {
     console.log('Google analytics is ready now');
      this.ga.trackView('test');
     // Tracker is ready
     // You can now track pages or set additional information such as AppVersion or UserId
   })
   .catch(e => console.log('Error starting GoogleAnalytics', e));

You should use documentation to integrate your iOS and Android application with Google Analytics.
