/**
 * Generate a lookup URI that will populate the quick contact with the number. Used when the lookup
 * URI is not available (non-contact and no other sources). The info is encoded into a JSON string
 * that is not governed by any public interface. URI format:
 * content://com.android.contacts/contacts/lookup/encoded/[JSON]
 *
 * <p>The JSON is a object containing "display_name", "display_name_source" ({@link
 * DisplayNameSources}), and several {@link ContactsContract.Data} rows keyed by the {@link
 * ContactsContract.Data#MIMETYPE}. In this case only {@link
 * ContactsContract.CommonDataKinds.Phone#CONTENT_ITEM_TYPE} is available.
 *
 * <p>Example JSON:<br>
 * {"display_name":"+1 650-253-0000","display_name_source":30,"vnd.android.cursor.item\/contact":{
 * "vnd.android.cursor.item\/phone_v2":[{"data1":"+1 650-253-0000","data2":12}]}}
