*Example:<code>
*Dim Contacts1 As Contacts
*Dim listOfContacts As List
*listOfContacts = Contacts1.FindByName("John", False)
*For i = 0 To listOfContacts.Size - 1
* Dim Contact As Contact
* Contact = listOfContacts.Get(i)
* Log(Contact) 'will print the fields to the LogCat
* Dim photo As Bitmap
* photo = Contact.GetPhoto
* If photo <> Null Then Activity.SetBackgroundImage(photo)
* Dim emails As Map
* emails = Contact.GetEmails
* If emails.Size > 0 Then Log("Email addresses: " & emails)
* Dim phones As Map
* phones = Contact.GetPhones
* If phones.Size > 0 Then Log("Phone numbers: " & phones)
