Context Missing on Initial App Lifecycle Events

[kylegwalsh]

It looks like the context and library information is missing on initial App Lifecycle events. The only thing I can think of is that there may be some kind of race condition with the initialization of the library and the sending of the first few lifecycle events.

• analytics-react-native version: 2.1.4-beta
• React Native version: 0.64.3
• Both iOS and Android

Steps to reproduce

1. Call createClient and attach appLifecycleEvents boolean:

const platformAnalytics = createClient({
  writeKey: Platform.select({
    ios: config.analytics.writeKeys.ios,
    android: config.analytics.writeKeys.android,
    default: '',
  }),
  trackAppLifecycleEvents: true,
  trackDeepLinks: true,
});

2. Reinstall and open app

Expected behavior

App Lifecycle events would come in with complete context and library information (like the other events do after initialization):

{
  "context": {
    "app": {
      "build": "1.0.2",
      "name": "App Name",
      "namespace": "com.app",
      "version": "1.0.2"
    },
    "device": {
      "adTrackingEnabled": false,
      "id": "XXXXX-XXX-XXX-XXX-XXXXX",
      "manufacturer": "Apple",
      "model": "iPhone12,1",
      "name": "iPhone",
      "type": "ios"
    },
    "ip": "XX.XXX.XXX.XX",
    "library": {
      "name": "@segment/analytics-react-native",
      "version": "2.1.4-beta"
    },
    "locale": "en-US",
    "network": {
      "cellular": false,
      "wifi": true
    },
    "os": {
      "name": "iOS",
      "version": "15.2.1"
    },
    "screen": {
      "height": 896,
      "width": 414
    },
    "timezone": "America/New_York",
    "traits": {}
  },
 "event": "Application Installed",
  ...
}

Actual behavior

App Lifecycle events come in without any context or library information:

{
  "context": {
    "library": {
      "name": "unknown",
      "version": "unknown"
    }
  },
  "event": "Application Installed",
  ...
}

I did some additional testing on different versions of this library and it looks like v2.0.0-pilot does not suffer from this issue (it sends in the correct context on LifeCycle events).

Hi Kyle, thanks for the report. I confirmed a repro, seems to be happening only on the first launch after an installation in the latest version of the library.
I'm working on a fix for the next version of the lib

@oscb No problem, thanks for the update!

@kylegwalsh fixed in v2.1.5-beta

@alanjcharles I'm observing the same issue with the currently most up to date version 2.1.11. Any advice on how to solve this?

Hello. I am also observing this behavior with latest version (2.2.0) -- where the context.device does not include actual device information. Sample output

    "device": {
      "adTrackingEnabled": true,
      "advertisingId": "CF8EAEA5-0000-481D-0000-25140DB49B96",
      "trackingStatus": "authorized"
    },

This is how I am setting up the library + plugins

import { createClient } from '@segment/analytics-react-native'
import { FacebookAppEventsPlugin } from '@segment/analytics-react-native-plugin-facebook-app-events'
import { FirebasePlugin } from '@segment/analytics-react-native-plugin-firebase'
import { IdfaPlugin } from '@segment/analytics-react-native-plugin-idfa'

const segmentClient = createClient({
  writeKey: process.env.ANALYTICS_WRITE_KEY as string,
  trackAppLifecycleEvents: true,
  trackDeepLinks: true,
  collectDeviceId: true,
  debug: true,
})

segmentClient.add({ plugin: new IdfaPlugin() })
segmentClient.add({ plugin: new FacebookAppEventsPlugin() })
segmentClient.add({ plugin: new FirebasePlugin() })

export default segmentClient

analytics-react-native version: 2.2.0
Integrations versions (if used): idfa: 0.2.1
React Native version: 0.64.3
iOS or Android or both?: ios
