I have found out that on Android contact, at least HTC Sense stores Facebook ID with the following mime type: vnd.android .cursor.item / vnd.facebook.profile This is different from their mimetype formats like com.htc.socialnetwork.facebook / smallavatar
I wonder where from I get a list of officially supported mimates for Android?
Anyone on Android "except that they are documenting in random places in Android SDK, usually On CONTENT_TYPE public static data subscribers (e.g., android.provider.ContactsContract.Contacts.CONTENT_TYPE ).
To do the best of my knowledge, HTC Sense is not SDK, and therefore is not "officially supported mimetap" for Android, which is related to any version.
