addTtsSpan

Added in API level 23

public static void addTtsSpan (Spannable s, 
                int start, 
                int endExclusive)

Attach a TtsSpan to the supplied Spannable at the indicated location, annotating that location as containing a phone number.

Parameters
`s`	`Spannable`: A `Spannable` to annotate.
`start`	`int`: The starting character position of the phone number in `s`.
`endExclusive`	`int`: The position after the ending character in the phone number `s`.

                String number2,

Determines if two phone numbers are the same.

Matching is based on compare(java.lang.String, java.lang.String), matching takes into account national dialing plans rather than simply matching the last 7 digits of the two phone numbers. As a result, it is expected that some numbers which would match using the previous method will no longer match using this new approach.

Parameters
`number1`	`String`: This value cannot be `null`.
`number2`	`String`: This value cannot be `null`.
`defaultCountryIso`	`String`: The lowercase two letter ISO 3166-1 country code. Used when parsing the phone numbers where it is not possible to determine the country associated with a phone number based on the number alone. It is recommended to pass in `TelephonyManager#getNetworkCountryIso()`. This value cannot be `null`.

Returns
`boolean`	True if the two given phone number are same.
