Public Methods

public static String calledPartyBCDFragmentToString (byte[] bytes, int offset, int length)

Added in API level 1

Like calledPartyBCDToString, but field does not start with a TOA byte. For example: SIM ADN extension fields

public static String calledPartyBCDToString (byte[] bytes, int offset, int length)

Added in API level 1

3GPP TS 24.008 10.5.4.7 Called Party BCD Number See Also TS 51.011 10.5.1 "dialing number/ssc string" and TS 11.11 "10.3.1 EF adn (Abbreviated dialing numbers)"

Parameters
bytes the data buffer
offset should point to the TOA (aka. TON/NPI) octet after the length byte
length is the number of bytes including TOA byte and must be at least 2
Returns
  • partial string on invalid decode FIXME(mkf) support alphanumeric address type currently implemented in SMSMessage.getAddress()

public static boolean compare ( String a, String b)

Added in API level 1

Compare phone numbers a and b, return true if they're identical enough for caller ID purposes.

public static boolean compare ( Context context, String a, String b)

Added in API level 5

Compare phone numbers a and b, and return true if they're identical enough for caller ID purposes. Checks a resource to determine whether to use a strict or loose comparison algorithm.

public static String convertKeypadLettersToDigits ( String input)

Added in API level 1
