Android Question Launch App from ulr and share data b4x?

[ilan]

hi

is it possible to create an url where the user clicks on it and if the app is installed it will open and a value is also sent via this url?
like youtube url does. user share a video via url link. if someone clicks on it it opens the youtube app and load the video.
is something like this possible in b4x language? so for b4a and b4i?

i found that it is possible for b4a using <intent-filter>

thanks guys now the question is this.

what will happen if one user is on ios and send the url to user that is on android?
is it possible to create a universal url that will work on both platform?

EDIT: so i will explain what i mean.
the link should be shared using whatsapp and clicking on it should open the app and read the string that is shared with the url (like a id).

In B4I you define a URL scheme e.g. b4x.com and then everything that is clicked with the link b4x.com opens your app.

The same in B4A:

AddActivityText("main",
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT"></category>
   
   <data android:scheme="https" />
   <data android:host="yoururl.com" />
</intent-filter> )

then if a user opens a link with your url, then your app starts and in the main module check the intent like:

If    Intenter.GetData.Contains("https://yoururl.com/") Then

I have the code from a project from 2018.

Opening a App with a URL is one thing. And it´s working.

The other thing is that

Firebase Dynamic Links | Firebase Documentation

Firebase Dynamic Links are links that work the way you want, on multiple platforms, and whether or not your app is already installed.

firebase.google.com

which is the feature behind that what you are requesting here is deprecated now. Service shutdown next year.

Handling Android App Links | Android Developers

developer.android.com

This is maybe/probably what we have to use

 

[Alexander Stolte]

how would the url look like?

yoururl.com?contentid=20

 

[ilan]

yoururl.com

here i should put the peckage url?

 

[DonManfred]

here i should put the peckage url?

there is no PACKAGE-URL involved.
Check the tutorial i linked. it must be set in the manifest.

I never used applinks though. So i can´t really help.

 

[Alexander Stolte]

here i should put the peckage url?

no. Your url of your public link of your backend.

 

[ilan]

no. Your url of your public link of your backend.

sorry i dont understand.

what backend?

 

[aeric]

sorry i dont understand.

what backend?

A domain name if you have one.

 

[ilan]

I want to share a link that will open a mobile app that is installed inside my phone.

what has my domain to do with that?
Sorry i dont follow up

 

[Alexander Stolte]

A domain name if you have one.

he should have, after all he wants to share a link from his app with dynamic content such as a video. Otherwise he would have formulated his question differently.

 

[Alexander Stolte]

like youtube url does. user share a video via url link. if someone clicks on it it opens the youtube app and load the video.

Isn't that exactly what you want? Youtube creates a shared link e.g. shared.youtube.com?videoid=2839347394

Youtube has registered the URL scheme youtube.com in their app, now whenever someone opens a link with youtube.com, the youtube app opens and they then read the intent and load the video from their backend based on the videoid.
