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.

Event is not logged on Firebase

I'm using Firebase on my Android app.
I'm using this package for my react-native project. I don't get any errors when I'm using it. However, events are not logged. Any help with this? Thanks!
I'm implementing the code like:
Analytics.setUserId(user.uid)
Analytics.logEvent('view_item', {
'item_id': 'login'
});

If you read this (Firebase documentation), you can see that it's a custom event, the custom events not appear on control panel but you can see that in audiences and as a filters for firebase analytics. If you want that your event is showed in your control panel you need to use a general events, you can learn more about them here, when you use the user properties or regular events the firebase needs 24h hours to recompile information and show it on control panel. Tell me if I helps you! Greetings!

When your code triggers a "view_item", it is supposed to "trigger" an existing event from the firebase analytics console.
So you need to create an event that will handle the "view_item" event in your code.
From the console in analytics, you need to create a new event named "view_item_trigger" for example add the following condition:
"if event_name is equal to 'view_item' ".
The view_item_trigger event will now appear in the debug view

Firebase Analytics APP_OPEN on Android

I made an Android app and I have integrated some tools of Firebase, but when I include the Firebase Analytics in the event APP_OPEN Android Studio shows that "I need out bundle", but in the docs of Firebase the method I should not send bundle. How resolve this problem?

The Bundle parameter is nullable. You can pass null if you don't intend to pass any parameters along with the APP_OPEN event. Note that even if no parameters are suggested for APP_OPEN, you are free to log up to 25 parameters in case you have some context that you would like to capture with the event (for example, you could pass a parameter that indicates how much time has elapsed since the previous APP_OPEN event).

Google Tag Manager for Xamarin Android app

As of my googled data, i got to know how to integrate GTM with the xamarin app. Based the url here.
The Tag manager is able to push the events to the GTM.
So question is, how to get the application data associated with GTM in the Google Analytics.
I get some links and videos while surfing for this, all are explaining about the GA for Web applications. Am looking the same for Xamarin Android application.
Edit:
Adding to the question, Will GTM capture all the button clicks with out pushing the data?
Will the data like 'submit button clicked' is transferred to GA via GTM?
Thanks

Suppose you have an image and want to know how many people clicked on it.
When the user clicks on the image you run this piece of code:
var dataLayer = new Dictionary <string, object> ();
dataLayer.Add ("event", "imageClick");
dataLayer.Add ("imageName", "Bart Simpson");
Android.Gms.Tagmanager.TagManagerClass.GetInstance (context).DataLayer.Push (dataLayer);
To get this data on GA through GTM you have to follow these steps on your GTM Container:
Create a new TAG
Choose Google Analytics as the product
Set the GA's Tracking ID and Track Type to Event
Set the Category to {{Platform}} (this will get Android)
Set the Action to {{Event}} (this will get imageClick)
Set the Label to a new Variable of the DataLayer type and named as imageName (this will get Bart Simpson)
Set Fire On to Any Event (this will trigger everytime an event is pushed to GTM)
Save and publish your container
Now you can see the events popping in you GA Console. You can send multiple variables in one push, but you will have to create multiple Tags with different events to see them in GA.
Edit:
No, you must push events to the DataLayer.
Only if you configure the TAG as explained above.
On GTM there is basic tracking for web that is the same as inserting the google analytics tracking code on each page of your website, but that only works for basic stuff like page views, not custom events on buttons.

Implementing Adword Remarketing with GTM Android

I am implementing GTM in Android project which will not use GoogleAnalytics SDK or Adword SDK,but I want data in Google Analytics and Adword.
In order to achieve this,
I have implemented Google Anaytics tag in GTM,Added Rule {Always},
Screen Name data is being sent to GTM which is reflected in Analytics,This is tested and working properly
I need InstallReferrals for Application which also should manage through GTM.
To achieve this,
Added a tag in GTM for Adword with the type Adword Remarketing,
Added ConversionId and label from Adword.
Added tagmanager.InstallReferralService and tagmanager.InstallReferralReceiver to Android manifest.xml.
According to source code of InstallReferralService it passes data to CampaignTrackingService of Analytics,which should upload data to Adword and Google Analytics.
But I am unable to get any data.
Please correct me if I am doing anything wrong in this process.
I also need Adword Conversion Tracking to be used through GTM without Adword SDK.
Not sure how to achieve this.
