How to use it?

There are two ways to use this library:

EmojiUtils

Exposes two methods:

1.To replace all emojis found in a string by their aliases, use EmojiUtils#toAlias(String).

For example:

String str = "What a nice day 😍, Let's go outside 😗";
String result = EmojiUtils.toAlias(str);
System.out.println(result);
// Produces:
// "What a nice day :smiling_face_with_heart_eyes:, Let's go outside :kissing_face:"

2.To replace all aliases found in a string by their unicode, use EmojiUtils#toEmoji(String).

For example:

String str = ":smiling_face_with_halo: I am sending you a :love_letter: :upside_down_face::upside_down_face:";
String result = EmojiUtils.toEmoji(str);
System.out.println(result);
// Produces:
// "😇 I am sending you a 💌 🙃🙃"
