Iionic 2 Google Analytics integration

I would like to use GA for my Ionic 2 app but for hybrid applications it looks a little bit tricky.
In my app.component I have:

this.platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.

      GoogleAnalytics.startTrackerWithId(this.config.googleAnalyticsId).then(() => {
        console.log(this.TAG + ' ANALYTICS+');
      }).catch((err) => {
        console.log(this.TAG + ' ANALYTICS- ' + err);
        .then((_success) => {
        }).catch((_error) => {

And got such error log:

I: Google Analytics 10.2.98 is starting up. To enable debug logging on a device run:
     adb shell setprop log.tag.GAv4 DEBUG
     adb logcat -s GAv4
I: Logger is deprecated. To enable debug logging, please run:
   adb shell setprop log.tag.GAv4 DEBUG

The straightforward goal for me is to collect information about bugs during beta-testing. Because I didn’t find enough information about this quite new subject for me, any hints or best practices would be appreciated.

What kind of bugs are you trying to collect? (Native) App crashes? Javascript errors? Manual events logging?
