Android Get Country Emoji Flag Using Locale

Question

I have seen that since Lollipop, Android has built in Emoji flags for different countries. Is it possible to use the devices locale to retrieve the

Answer 1

Based on this answer, I wrote a Kotlin version below using extension function.

I also added some checks to handle unknown country code.

/**
 * This method is to change the country code like "us" into                                                                     

                                                        
            

Answer 2

When I first wrote this answer I somehow overlooked that I've only worked on Android via React Native!

Anyway, here's my JavaScript solution that works with or without ES6 support.

    function countryCodeToFlagEmoji(country) {
      return typeof String.fromCodePoint === "function"
        ? String.fromCodePoint(...[...country].map(c => c.charCodeAt() + 0x1f185))
        : [...country]
            .map(c => "\ud83c" + String.fromCharCode(0xdd85 + c.charCodeAt()))
            .join("");
    }

console.log(countryCodeToFlagEmoji("au"));
console.log(countryCodeToFlagEmoji("aubdusca"));

If you want to pass in the country codes as capital letters instead, just change the two offsets to 0x1f1a5 and 0xdda5.

Answer 3

I am using this so easily. Get the Unicode from here.

For Bangladesh flag it is U+1F1E7 U+1F1E9 Now,

{...

 String flag = getEmojiByUnicode(0x1F1E7)+getEmojiByUnicode(0x1F1E9)+ " Bangladesh";
    }
    public String getEmojiByUnicode(int unicode){
        return new String(Character.toChars(unicode));
    }

It will show > (Bangladeshi flag) Bangladesh

Answer 4

You can get the country code very simple. I want to talk about flag selection according to country code.

I wrote a class about it and it is very simple to use.

usage:

String countryWithFlag = CountryFlags.getCountryFlagByCountryCode("TR") + " " + "Türkiye";

Output :

I was looking for that too but I don't think it's possible yet.

Have a look here: http://developer.android.com/reference/java/util/Locale.html

No mentioning about flags.

Alternately you can check the answer here:

that might help you.

Answer 6

Emoji is a Unicode symbols. Based on the Unicode character table Emoji flags consist of 26 alphabetic Unicode characters (A-Z) intended to be used to encode ISO 3166-1 alpha-2 two-letter country codes (wiki).

That means it is possible to split two-letter country code and convert each A-Z letter to regional indicator symbol letter:

private String localeToEmoji(Locale locale) {
    String countryCode = locale.getCountry();
    int firstLetter = Character.codePointAt(countryCode, 0) - 0x41 + 0x1F1E6;
    int secondLetter = Character.codePointAt(countryCode, 1) - 0x41 + 0x1F1E6;
    return new String(Character.toChars(firstLetter)) + new String(Character.toChars(secondLetter));
}

Or in Kotlin, for example (assuming UTF-8):

val Locale.flagEmoji: String
    get() {
      val firstLetter = Character.codePointAt(country, 0) - 0x41 + 0x1F1E6
      val secondLetter = Character.codePointAt(country, 1) - 0x41 + 0x1F1E6
      return String(Character.toChars(firstLetter)) + String(Character.toChars(secondLetter))
    }

Where 0x41 represents uppercase A letter and 0x1F1E6 is REGIONAL INDICATOR SYMBOL LETTER A in the Unicode table.

Note: This code example is simplified and doesn't have required checks related to country code, that could be not available inside the locale.
