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.

Firebase DynamicLinks - Can i see analytics of link created by the new buildShortDynamicLink API?

I'm using the new buildShortDynamicLink API of Firebase (And it's great).
And i see there are two methodes for the ShortDynamicLink result:
Uri shortLink = task.getResult().getShortLink();
Uri flowchartLink = task.getResult().getPreviewLink();
I tried to use both but still the link doesn't apear in the Firebase dashboard.
What is getPreviewLink used for anyway?
Thanks.

Only analytics for links created in the console will show up in the console.
You can still access the analytics for your short links created via the API by using the Firebase Dynamic Links Rest API as described here (https://firebase.google.com/docs/reference/dynamic-links/analytics).
The getPreview returns the url to a visual flowchart that helps illustrate clearly how the link will work in each context. You can use it to debug the link if you want and to visually see how it will behave in different contexts.
Full disclosure: I work for Firebase.

This is expected. Only links created through the dashboard will show up there.
Think about it from this perspective: when your users are creating hundreds or even thousands of links per day, it will quickly make the dashboard completely useless if they all show up there.
At Branch.io (full disclosure: I'm on the Branch team), we take the same approach by default, though we do offer a manual flag you can change on programmatically-generated links to have them show up on the dashboard if desired.

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.

working on an Android Game, stuck at In app purchase programming

I am working on an Android Game. I got stuck at In app purchase programming.
I have decided to use Soomla Unity IAP plugin.
I tried their sample program of muffins, that worked well.
But I did not get idea how would I know if some one purchased coins(Or any good) from my game.
I have seen some videos on youtube, I have gone through git hub page of SOOMLA but didn't find anything which can clear my doubts.
Please help me out guys Or refer any worthy material you know.
Thank you !!

Your question isn't specific enough so I'll try to address several ways to go:
First, assuming you are selling coins for real money (market purchases), you want to use SOOMLA's event system to handle events when they're dispatched. A common event to register a handler for is OnMarketPurchase in which you will get notified when users purchase things with Google Play, Apple App Store, or Amazon, depending on your platform:
StoreEvents.OnMarketPurchase += onMarketPurchase;
public void onMarketPurchase(PurchasableVirtualItem pvi, string payload,
Dictionary<string, string> extra) {
// pvi - the PurchasableVirtualItem that was just purchased
// payload - a text that you can give when you initiate the purchase operation and
// you want to receive back upon completion
// extra - contains platform specific information about the market purchase
// Android: The "extra" dictionary will contain "orderId" and "purchaseToken"
// iOS: The "extra" dictionary will contain "receipt" and "token"
// ... your game specific implementation here ...
}
Second, you can use the StoreInventory class to query a user's inventory and thus know his \ her balances and what they've purchased:
StoreInventory.GetItemBalance("currency_coins");
Third - the method SoomlaStore.RefreshInventory (which runs by default on Android builds, but not iOS) should all also restore the user's previous transactions for lifetime goods, in which you can also handle triggered events, so that's another way of telling if a user has previously purchased something ("Remove Ads" for example).

Google analytics version 4 not able to send custom dimension

I am trying to send the custom data in google analytics version 4 where the sending procedure seems to be different then previous version, I have create a custom dimention from google analytics web page then with the corresponding index I am sending the repective value as mention below,
Tracker tracker = ((Application) getApplication())
.getTracker(TrackerName.APP_TRACKER);
tracker.send(new HitBuilders.AppViewBuilder()
.setCustomDimension(1, "info1")
.build());
tracker.send(new HitBuilders.AppViewBuilder()
.setCustomDimension(2, "info2")
.build());
from the logs it seems that the data is send but not sure as I am unable to view any data in the google analytics web page.

You'll have to create a custom report and select the custom dimension, and any metrics associated with that custom dimension. For some reason Google hasn't (and who knows if they will) update the Custom Variables report.

You can define a custom report (Google Analytics > Customization (top tab)), but you need to make sure you select the right Metric or your information will not appear (e.g. ga:hits). https://support.google.com/analytics/answer/1151300?hl=en
Alternatively you can query the information through Google Analytics Query Explorer, although not choosing the correct dimension / metric will result in no data to appear (e.g. ga:dimension1 + ga:hits). http://ga-dev-tools.appspot.com/explorer/
Obviously might take a few good seconds / couple of minutes for information to be available, and important for fresh information make sure the date range includes today (yes, it happens to best of us to refresh furiously and find out Google Analytics date range was up to yesterday :-)
