65279 Error

When Android Studio IDE compiler occurs error about 65279 message.

Because code file (.java) has so illegal character, so .. you need to modify your code file codepage like that UTF-8 to UTF-8(NON BOM).

Example: Using your Notepad++ software to open code file (.java) and change your codepage(UTF-8 to UTF-8(NON BOM)) then save it.
