Question

I have some problem with displaying emoji icon in Android TextView

First, I found a list of emoji icon in unicode at here:
http://www.easyapns.com/category/just-for-fun

Second, I found how to display emoji icon at here:
https://github.com/sharakova/EmojiTextView/blob/master/src/jp/sharakova/android/emoji/EmojiTextView.java

The EmojiTextView.java can convert the predefined character to emoji icon automatically. Therefore, I want to replace all the occurrences of emoji icon in a String to some predefined character, and put the result to EmojiTextView.java
The problem is my code cannot recognize emoji icon in the String which contains emoji icon.

Here is my code snippet – I am trying to find if the input match any unicode of emoji icon:

// Array list of all emoji icon
private static final String[] ArrayEUnicodeString ={
    "\uE415",
    "\uE056",
    "\uE057",
    ...
}

// Nothing matched when it receive emoji icon with unicode "\uE415" from iphone. 'input' is message received from XMPP server
for (int i=0; i < emojiLength; i++)
{

    if (input.getBytes() == ArrayEUnicodeString[i].getBytes())
        Log.e("test", "ArrayEUnicodeString found");
}
// Note: iphone can display the emoji icon if I send "\uE415"

I am not good at unicode comparison/convention. Can somebody help me please, thanks!

You could also try to find the emoji using a regular expression: “[\ue415\ue056\ue057]”, instead of comparing the bytes.
