Answer 1

Found a solution:

In my unicode I replaced 'U+' by '0x'

Example: replace 'U+1F60A' by '0x1F60A'

This way I got an 'int' like

int unicode = 0x1F60A;

Which can be used with

public String getEmojiByUnicode(int unicode){
    return new String(Character.toChars(unicode));
}

So Textview displays

NOte: For Kotlin

fun getEmoji(unicode: Int): String { return String(Character.toChars(unicode)) }

You can directly use Emojis in string resources by using the decimal code like this:

�

for example:

<string name="emoji">I am happy &#x128522;</>

NOTE: The x is required in android vs standard XML escape sequences.
