   /**
-   * Find the cursor pointing to a number that matches the number in a contact lookup URI.
-   *
-   * <p>When determining whether two phone numbers are identical enough for caller ID purposes, the
-   * Contacts Provider uses {@link PhoneNumberUtils#compare(String, String)}, which ignores special
-   * dialable characters such as '#', '*', '+', etc. This makes it possible for the cursor returned
-   * by the Contacts Provider to have multiple rows even when the URI asks for a specific number.
-   *
-   * <p>For example, suppose the user has two contacts whose numbers are "#123" and "123",
-   * respectively. When the URI asks for number "123", both numbers will be returned. Therefore, the
-   * following strategy is employed to find a match.
-   *
-   * <p>If the cursor points to a global phone number (i.e., a number that can be accepted by {@link
-   * PhoneNumberUtils#isGlobalPhoneNumber(String)}) and the lookup number in the URI is a PARTIAL
-   * match, return the cursor.
-   *
-   * <p>If the cursor points to a number that is not a global phone number, return the cursor iff
-   * the lookup number in the URI is an EXACT match.
-   *
-   * <p>Return null in all other circumstances.
-   *
-   * @param cursor A cursor returned by the Contacts Provider.
-   * @param columnIndexForNumber The index of the column where phone numbers are stored. It is the
-   *     caller's responsibility to pass the correct column index.
-   * @param contactLookupUri A URI used to retrieve a contact via the Contacts Provider. It is the
-   *     caller's responsibility to ensure the URI is one that asks for a specific phone number.
-   * @return The cursor considered as a match by the description above or null if no such cursor can
-   *     be found.
