Android Question Link in a webview dont open an app

[asap74]

I open a web Page by a webview.
In the HTML i ve a link (a href) that point to an Istagram profile.
I would like to open Istagram app at the selected profile.
In Chrome It works, in the webview It opens the Istagram website.

I ve also tried something like this (googling stack overflow).
<a href="fb://profile/fbID">Facebook</a>
<a href="twitter://user?screen_name=username">Twitter</a>

Is maybe something related to manifest?
Is It a good idea to have a button outside webview to open Istagram app if istalled?

Hoping to have explained the problem clearly.
Thank you.

Although very old, you might want to take a look at this post that talks about starting an app from an email link
https://www.b4x.com/android/forum/threads/start-app-from-uri-in-email.27052/#content as a start.

hi and thank you!
maybe we are talking about "intent", i found a tutorial on this forum:

https://www.b4x.com/android/forum/threads/intent-for-beginner-messages-between-apps.123680/#content

i try to write this:
Private Sub Button1_Click
Dim intent1 As Intent
intent1.initialize(intent1.ACTION_VIEW,"https://instagram.com/blahblah=")
intent1.setpackage("com.instagram.android") 'target app package name
intent1.setType("text/plain") 'mime types ex: text/plain
'intent1.PutExtra("android.intent.extra.*","your message content data")
StartActivity(intent1)
End Sub

in your example the manifest contains:
AddActivityText("main",
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT"></category>
<category android:name="android.intent.category.BROWSABLE"></category>
<data android:scheme="http" />
<data android:host="mydomain.myd" />
</intent-filter>

and this:
android:targetSdkVersion="14"

i haven't modified my manifest.

i've also read your article.

my code crash the app when i click the button.

this is the first step: click a sinple button and open istagram.

currently it's not working.

thank you.

i solved this way, any comment to improve is welcome! thank you to all!

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    WebView1.LoadUrl("www")
    WebView1.ZoomEnabled=False
End Sub

'You can see the list of page related events in the B4XPagesManager object. The event name is B4XPage.

Private Sub WebView1_OverrideUrl (Url As String) As Boolean
    If Url.ToLowerCase.StartsWith("https://instagram.com") Then
        Dim intent1 As Intent
        intent1.initialize(intent1.ACTION_VIEW,"https://instagram.com/XXX?igshid=XXX=")
        intent1.setpackage("com.instagram.android") 'target app package name
        'intent1.setType("text/plain") 'mime types ex: text/plain
        'intent1.PutExtra("android.intent.extra.TEXT","your message content data")
        'intent1.SetComponent("com.instagram.android/.activity.ShareHandlerActivity")
        StartActivity(intent1)
    Else
        WebView1.LoadUrl(Url)
    End If
    Return True
End Sub
