Hi,

Using this code, you can add a contact.
B4X: 
    Dim i As Intent
    i.Initialize("android.intent.action.INSERT", "content://com.android.contacts/contacts")
    StartActivity(i)
How to check if a contact was added?

In fact, it is not the best solution, but if there is no other solution ...

What is the function "StartActivityForResult", so what can you do?

I would say you can do that easily and effectively using ContentObserver (it will immediately detects the change/add), but unfortunately we do not have it implemented yet in B4A...
However I may be wrong (never tried so before)...

Or... you can use ContentResolver to check if this contact exists there... ContentResolver can be used in B4A.
B4X: 
Sub FindContact(phonenumber As String) As String

    Dim phonesUri As Uri, name As String = ""
    phonesUri.Parse("content://com.android.contacts/phone_lookup")
    phonesUri.WithAppendedPath(phonesUri, phonenumber)
    Dim phones As Cursor = cr.Query(phonesUri, Array As String("number", "display_name"),"number = ?", Array As String(phonenumber), "")
    If phones.RowCount > 0 Then
        phones.Position = 0
        name = phones.GetString("display_name")
    End If
    phones.Close
    Return name

End Sub
