In the application I am building I am accessing the contacts of the mobile, but I need to know whether those contacts are editable (like the ones of the google account) or not (like the ones coming from Skype). I haven't found anything related to this topic anywhere, but I see that the contacts application from Samsung is able to distinguish between them, so it has to be possible. Any help or guide would be very appreciated. Thanks a lot!!
Well, it seems that maybe what I am asking is not completely clear. This is my specific use case: I am building an app that has a map. From it you can access the contact list and when you select a contact, this will be shown in a balloon on the map. If that contact is writeable, you will have a button in that bubble to edit that contact. But if that contact is not writeable, that button will not appear.
