I have been searching and trying to find anything that could show me how to send an email by clicking on an email link in Webview, but haven't been able to. I have read about OverrideURL but doesn't figure it out
I would also like to know how yu can click on a link (?) with a phone number so you can call straight from the web page.

It should be pretty simple I would guess, but I haven't been able to figure it out

Anybody who can help?

Basically OverrideURL is the sub that's called before the page is loaded. So the order of operations is:

Link is pressed in webview -> OverrideURL -> New url is loaded -> PageFinished

So what you want to do is intercept all hyperlinks that start with "mailto:" within the OverrideURL sub.

This is easily done, like so:
B4X: 
Sub OverrideURL (Url As String)
   If url.IndexOf("mailto:") > -1 Then
      'Do what you want with the mailto link
   End If
End Sub
So now that you know the link pressed is a mailto link you can work with it.

Use the phone library (that is, check the "Phone" library in the IDE) for Email like so:
B4X: 
Dim Message As Email
Message.To.Add(url)
Message.Body = "Email body"
StartActivity(Message.GetIntent)

Bare in mind you need to strip the "mailto:" part from the Url string as well:
B4X: 
url.replace("mailto:","")

Altogether now!
B4X: 
Sub OverrideURL (Url As String)
   If url.IndexOf("mailto:") > -1 Then
      Dim Message As Email
      Message.To.Add(Url.replace("mailto:",""))
      Message.Body = "Email body"
      StartActivity(Message.GetIntent) 
   End If
End Sub

I don't have an answer for the numbers question although I imagine the solution will be quite similar.

Hi.

Don't forget that the OverrideUrl Sub should return a Boolean value to indicate whether the URL has been handled by your activity or not:

Basic4android - Views (Core)

So if your activity has handled a mailto link then OverrideUrl should return a True value otherwise it should return a False value.

Mailto: OverrideURL

Thanks.
This is how I made it work. Thought I'd share it in OverrideURL.

Dim p As PhoneCalls
Dim Message As Email

If Url.Contains("@") Then
' send email

Message.To.Add(Url)
' Message.Attachments.Add(File.Combine(File.DirRootExternal, "SomeFile.txt"))
Message.Subject = "Your Ad at PawsitesOnline.com"
StartActivity(Message.GetIntent)

Else

StartActivity(p.Call(Url))

End If
