Firebase dynamic link for not installed application

I have a problem with dynamic link at Firebase not redirecting me to Play Store if the application is not installed.
The dynamic link is defined as following:
The link preview (debug) show following picture:
according to this one if I click on the link and application is not installed I would be brought to Play Store. However it just opens a browser and opens the web link. The "Play Store" link though is functioning and brings me to the Play Store.
One more detail. When I click on the dynamic link on my Android phone I see three steps:
A browser window with "google.com" URL opens shortly.
Browser window is closed and I see original screen where I clicked on the link with a ring rotating for less than a second.
A browser windows opens again but this time with web link opened
And same happens even if the application is installed.
Is there a way to debug this behavior and get some better understanding of what's the reason?

As you mentioned it is in debug , i believe here that application is not present on playstore right now and that's why it is not redirecting you to playstore in case of app is not installed on your device but yes , it should open your app if it is already installed on your device
so make sure above scenario .. if flow is working same as mentioned then no worries everything is fine but if it is not working as mentioned then you need to mention code of creating link , manifest file , activity where you are handling it etc ..

So, it turned out my approach to dynamic links building was wrong. Dynamik link creation as shown in the question is a way to establish static links that don't change and have no parameters. It's usable to bring users to a specific part of your application that never changes.
In case of using dynamic link, which is dynamic in its nature like in my case - invitation link that allows to install application if it's not yet installed, run it and bring the user to a specific part of the application with parameters would be:
Define a URL prefix
Publish the application at Play Store at least in closed testing mode. Internal testing seems not to be enough because it's available only by internal testing ID and not the package ID.
Generate URL of type: https://myapp.page.link/?link=https://myapp.com/join/invitation_id&apn=com.myapp
That is enough to make work for Android. For iOS it's not tackled yet.

Android - Google OAuth 2 - twice response with different verifier code

I have an issue with Oauth Google on Android 9 and lower.
Settings :
I develop an application with :
Nativescript 7
Angular 11
nativescript-oauth2:3.0.3 plugin
The problem :
I am not sure the problem is from the nativescript-oauth2 plugin, perhaps my android application configuration or Google Frame.
I develop an OAuth login with Facebook and Google provider.
For Facebook, no problem.
Facebook use a web view browser, and Google use a native view browser.
For Google, see bellow :
on emulator with android 10 : all work fine
on emulator with android 8 or 9 :
it open the browser to login with Google => I choose my account => redirect to a Google Page with Waiting message => it never redirect to my app, and after a moment, it redirect to www.google.com
on real device (android 9) with multiple Google account, I have 2 behaviors :
First : it open the browser to login with Google => I choose my account => redirect to a Google Page with "Waiting" message => redirect to my App with The login operation was canceled error message
Second : it open the browser to login with Google => I wait a moment (per example 1 minute) => I choose my account => redirect to a Google Page with Waiting message => redirect to my App => it work fine
on other real Device with just one account Google (in android settings), it is ok
More details :
I debugged the application and the nativescript-oauth2 plugin.
I saw that the Google Frame with Waiting message (after choose a google account) send 2 events to Android with differents values for the "code" parameter.
Of course the first code is expired/revoked and Google return an error.
In the OAuth Google documentation, this is the Step 4 which send 2 responses with 2 codes.
My question
Why the Google Frame browser send me 2 events ?
Code :

How to open an Android TV app with voice

Edit
The original post says that I can't open my test by saying "open test". Repeated attempts have shown that it does work...sometimes. Perhaps 90% of the time saying "open test" opens my test app, but the other times it does a media search. I can see the text that google is transcribing, so the two different outcomes aren't being caused by mistakes in the speech-to-text.
Original post
On an Android TV, I am able to open apps by clicking the remote's microphone button and saying "Open <appname>" (e.g. "Open youtube" or "open dailymotion"). I want this functionality in the app I develop. After deploying my app to the TV, I cannot open my app by saying "open test", where "test" is the value of android:label in the application element of AndroidManifest.xml.
I've tried this out with a basic Android-Studio generated TV projected, so my AndroidManifest.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest package="<my package>"
xmlns:android="http://schemas.android.com/apk/res/android">
<uses-feature
android:name="android.hardware.touchscreen"
android:required="false"/>
<uses-feature
android:name="android.software.leanback"
android:required="true"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="test"
android:theme="#style/Theme.Leanback">
<activity
android:name=".MainActivity"
android:icon="#drawable/app_icon_your_company"
android:label="test"
android:logo="#drawable/app_icon_your_company"
android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LEANBACK_LAUNCHER"/>
</intent-filter>
</activity>
</application>
</manifest>
How do I add this functionality?
I have two thoughts: that there is an Android Manifest property that I haven't found in my search, or that this functionality is only available for apps available in the play store. (If I use the mike to say "open dailymotion" when I don't have dailymotion installed, the top result is a link to the app on the play store, which makes me think this functionality is reliant on being indexed by google.)

You would want to use System voice action https://developers.google.com/voice-actions/system/

GoogleMap V2 loads map randomly android

I have implemented Google Map V2 in my application, Everything works just fine.
Checked on 2-3 mobiles and tabs it runs perfectly,
But it runs for 10 to 15 times a day on single device.,after that it does not load map on same device and gives following error.
05-06 07:17:41.866: E/Google Maps Android API(17217): Failed to load map. Could not contact Google servers.
In short, sometimes it displays map and sometimes it does not.
I m using map key generated from android debug key.
Please suggest some solutions for this.

I am experiencing the same problem, the maps are running OK on multiple devices, but randomly show a blank screen, sometimes for days.
When I debug the code I can see that all actions like adding markers, overlays, etc. are executed properly.
Also, no idea if this is related, but the Geocoder seems to be working correctly in the meanwhile, so it is definitely not related to an Google Services connectivity issue(or is it?).
Besides, the map also works fine offline and the cache data is stored properly (well, most of the time that is).
Clearing my app's cache and data also doesn't help. Nor does doing so for the Google Services app.
However, reinstalling the application seems to fix it for most of the time, but does not prevent it from reoccurring.

Add the following permission in your manifest file
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
There are Google Maps API v2 and Google Maps Android API v2.
You should use Google Maps Android API v2.

google map v2 grey blank page , only zoom is there

I am working in Iran, I had used Google map v1 for long time, now that I have to use Google map v2, I just can see a grey blank page with zoom icon only, I have done every thing based on Google instructions, I think I have done everything.
*I WANT TO KNOW IF THIS PROBLEM IS RELATED TO GOOGLE POLICY THAT MEANS SOME COUNTRIES ARE NOT ALLOWED TO USE GOOGLE PLAY SERVICES AND MAP .... *
THIS IS A BIG PROBLEM FOR ME NOW

You Must Run your app in amulator having Following Configuration....
Google API(x86 System image)
Select checkBox indicating "Use Host GPU..."

If anything this could be related to Iran's policy and not Google's.
The problem you describe usually happens when you have a problem with the API key you have generated or the way you registered it in the Console.
You can go over this blog post I wrote on getting the Google API V2 key:
Google Map API V2 key

Maybe, you missed one of this:
Didn't include the Google API Key v2 in the manifest.xml
Didn't add the package name in Android maps Key(Console) , example:
ABczzisierkaiSAisi-Ka2;my.project.package
Didn't add Internet Permissions, on manifest.xml.
Your Android device doesn't have an internet connection
NOTE: If you are using a Virtual Device, it won't work, beacuase it needs Google Play Services

I used to face the same problem as yours. The first thing you need to check is Google Maps Android API Key. Then check the settings in AndroidManifest.xml. There are detail instructions in following link: Android Maps Android v2

yes, it's because of country ._.
i have this issue too on javaScript apis, but it works out with proxy..
