Configure Multiple Firebase Projects Runtime in iOS application and Firebase/Google Analytics

We are starting to migrate from Google Analytics to Firebase Analytics as it is going to be deprecated in a year. We have a need of initializing the firebase project runtime in our iOS application and we are following the steps mentioned here: https://firebase.google.com/docs/projects/multiprojects?authuser=0
Why do we need to initialize the firebase manually and at runtime? The details are in this issue: Switching between different firebase projects (runtime) in one single APK file
I posted that issue when we encountered a similar problem for push notifications on Android because at that time the documentation was not sufficient. It is really good to know that firebase documentation has been updated to reflect how to manually initialize the sdk for various platforms.
Problem: The problem that we are facing today is that once we initialize the SDK manually for say a "secondary" application and we try to use the firebase analytics, it fails with following error:
2018-12-20 17:14:33.526757-0800 App Name[9218:675367] 5.2.0 - [Firebase/Analytics][I-ACS025018] Event not logged. Call +[FIRApp configure]: AppLaunch
Below is the sample piece of code:
FIROptions *firoptions = [[FIROptions alloc] initWithGoogleAppID:#"Actual_GoogleAppId" GCMSenderID:#"Actual_GCMSenderId"];
firoptions.bundleID = #"actual.bundle.id";
firoptions.APIKey = #"actual-api-key";
firoptions.clientID = #"actual.client.id";
firoptions.databaseURL = #"https://actual.url";
firoptions.storageBucket = #"actualapp.appspot.com";
[FIRApp configureWithName:#"testApp" options:firoptions];
if ([FIRApp appNamed:#"testApp"]) {
[FIRAnalytics logEventWithName:#"AppLaunch" parameters:nil];
}
Looking at the error it tells us to use [FIRApp configure] which configures the default application from the GoogleService-Info.plist in the project. But we do not have GoogleService-Info.plist in our project as suggested in https://firebase.google.com/docs/projects/multiprojects?authuser=0.
TL;DR: We are initializing the firebase app manually in our iOS application using the API [FIRApp configureWithName:#"testApp" options:firoptions]; and the Firebase Analytics gives an error asking us to use default [FIRApp configure] which defeats the purpose of manual initialization.
Any help is greatly appreciated.

Firebase Analytics requires the file to be named GoogleService-Info.plist. Note the first paragraph of https://firebase.google.com/docs/projects/multiprojects?authuser=0 recommends differentiating multiple versions of it by putting them in different directories.

Firebase Dynamic Links - Can't get Url in android after install app from play store

If I install the app when clicking the dynamic link. All of that information from dynamic should be still available when I open the app for the first time.How can I get that information? It is not working when I use this: getInitialLink() returns Promise<string|null>;

Since, you haven't mentioned - I'm assuming you are having problems with shorter urls, if that's the case try putting the longer url.
Or refer here on Simon's answer: When I use the long instead of short links, everything works perfectly fine.
On Android, you use the getInvitation() method to get data from the Dynamic Link:
AppInvite.AppInviteApi.getInvitation(mGoogleApiClient, this, false).setResultCallback
(/* ... */);
Then, in the callback, you can get the data passed in the Dynamic Links link parameter by calling the getDeepLink() method:
Firebase Documentation - Use Case
For future reference or detailed answer on Firebase Dynamic Links
Behave just like normal Links
In cases where the application doesn’t require installation (say, if it’s already installed) then clicking the Dynamic Link will automatically open the link to the desired screen.
Dynamic Links have a very simple process flow:
The user begins by clicking the Dynamic Link
If the the needs of the Dynamic Link target are satisfied (this is, the application being installed) then the user is navigated to the target location
Otherwise, if the application requires install in order to navigate
to the Dynamic Link target, the the user is taken to the point of
install for the application. Once the application has been installed,
the user is navigated to the target location of the Dynamic Link
And if that wasn’t all, we can integrate Dynamic Links with Firebase Analytics to track the interaction with any links that we generate for our applications. But if we only require simple tracking, then we can use the automatic built-in analytics from the Dynamic Links panel within the Firebase Console where we can also obtain attribution and referrer information for interacted links with no extra effort required from our side.
What makes it different from Google Analytics?
One of the first things that came to my mind when I read about Firebase Analytics was, “What about my Google Analytics setup?”. So if you already have Google Analytics in place, then why would you make the switch to Firebase Analytics? Well, here’s a couple of differences between the two:
Audiences
We can use Firebase Analytics to create Audiences — these are groups of users that we can then interact with using other Firebase service such as Firebase Notifications and / or Firebase Remote Config.
Integration with other Firebase Services
An awesome thing with Firebase Analytics is that we can integrate other Firebase services with analytics. For example, creating an Audience of users who have experienced a crash reported through Firebase Crash Reporting.
Lower Method Count
The Google Analytics dependency on Android has a total count of 18,607 methods and has a total of 4kb used for dependancies. On the other hand, Firebase Core (for Analytics) has a method count of 15,130 and only 1kb used for dependancies.
Automatic Tracking
When we add the firebase core dependency, it will automatically begin tracking a collection of user engagement events and device information for us — this is useful if you’re looking to only collect the minimal data for your app.
Unlimited Reporting
For up to 500 events, Firebase Analytics provides us with unlimited reporting straight out of the box for free!
No Singleton Initialisation
When setting up Google Analytics on Android we are required to initialize a Singleton instance. Firebase Analytics are simply available by fetching the instance directly from where we wish to track data. This isn’t much effort obviously but just makes the setup flow slightly easier.
Single Console
All of the data for every Firebase service is available for a single console. That makes it both easier and quicker for us to navigate from checking the analytic stats for our app to viewing the latest crash reports.

It looks like this is a react-native-firebase open bug for android
For fix the only thing that is required to be changed in module code:
private boolean isInvitation(PendingDynamicLinkData pendingDynamicLinkData) {
return FirebaseAppInvite.getInvitation(pendingDynamicLinkData) != null;
}
to
private boolean isInvitation(PendingDynamicLinkData pendingDynamicLinkData) {
FirebaseAppInvite invite = FirebaseAppInvite.getInvitation(pendingDynamicLinkData);
if (invite != null && invite.getInvitationId() != null && !invite.getInvitationId().isEmpty()) {
return true;
}
return false;
}

Please Check Your Manifest file
open AndroidManifest.file => In your activity tag there is intent-filter tag put below line in that tag.
<data android:scheme="https" android:host="your.dynamic.link" />
<data android:scheme="http" android:host="your.dynamic.link" />
If already done then check this link for the full blog on the dynamic link with react native.

I hope this will help. sorry for the typos.

Creating Content Grouping on Android SDK

I am using the Android SDK to send data to Google Analytics. In this project I cannot use Firebase nor GTM. I should send hits directly to GA. I have already implemented everything, events included. But I cannot create Content Groupings. I think that the follow code is deprecated, isn't it?
mTracker tracker = GoogleAnalytics.getInstance(this).getTracker("UA-XXXXXXXX-X");
mTracker.set(contentGroup(1), "Level");
Which is the correct implementation for creating Content Grouping with the Android SDK without using other platforms (I mean sending everything directly to GA)?
Thanks a lot.

Android GTM: Possible to start new Google Analytics session manually?

So I'm working on implementing the latest Google Tag Manager into my application for use with Google Analytics. It's in place and everything is working great, but I do have a question.
Is it possible to manually start a new session within GA while using GTM to fire all of the events? For example, when I user logs out I would like to begin a new session, can I force that to happen using GTM?
Thanks!
OSFTW

You can do this with the sessionControl config var.
In GTM, in your GA tag config, it's under
More Settings > Fields to Set
Click the Add Field button, then for Field Name put sessionStart and for Value put "end" to force end of the current session or "start" to force (re)start of session.
Notes:
If you are using a Web Container Type, this is only available for Universal Analytics Tag Type. The Classic Google Analytics Tag Type does not have an equivalent, though you can maybe do some magic with _setSessionCookieTimeout if you're feeling ambitious.
If the GTM container is created as Mobile Container Type, it will only show Google Analytics as a Tag Type option, but this is a misnomer. Under the hood, GTM uses the Measurement Protocol for Mobile containers, and sessionControl is available for that.

How to use tracking id of google analytics in android app?

I am trying to integrate google analytics with my android app. I followed the steps in the following link:
https://developers.google.com/analytics/devguides/collection/android/v3/#manifest
Then i tried the look at the statistic of my app, but it seems like analytics is not working, i must have done something wrong. The problem is, in those steps we do not make use of the tracking id, and in google analytic's web site, it says that
Download the Google Analytics SDK for Android or iOS and implement the tracking code,
including this tracking ID.
What does it mean to "implement the tracking id"? What should i do about this can anyone help me?
Thanks

Use this:
Tracker tracker = GoogleAnalytics.getInstance(context).getTracker(ga_trakingId);
Then you can SET some variables, that will be send to GoogleAnalytics:
tracker.set(Fields.APP_NAME, "Best Android Application");
tracker.set(Fields.APP_VERSION, "1.0");
To SEND some info, events:
tracker.send(MapBuilder.createEvent("UX", "App Launch", null, null).build());
You must watch Behind the Code: The Google Analytics v3 Mobile SDKs, all info from there.
Update 1
Google Analytics API v4 you should create google-services.json file from here and then you can use:
public Tracker getTracker() {
return GoogleAnalytics.getInstance(this).newTracker(R.xml.global_tracker);
}
And then you canuse it like this way:
getTracker().setScreenName("SomeScreenOrActivityName");
getTracker().send(new HitBuilders.ScreenViewBuilder().build()); // send screen name

The new process generates a file by Google which is called GoogleService-Info.plist.
This file contains (key, string) and one of them is:
<key>TRACKING_ID</key>
<string>*YOUR TRACKING ID*</string> // Auto generated by GAI
Just open the file and confirm that this is your tracking ID.
