How to send emoji in intent to whatsapp?

Question

I know that we can send plain text to whatsapp through an intent like :

 Intent sendIntent = new Intent();
 sendIntent.setAction(Intent.ACTION_SEND);
 sendIntent.putExtra(Intent.EXTRA_TEXT,"Text to be sent on whatsapp");
 sendIntent.setType("text/plain");
 sendIntent.setPackage("com.whatsapp");
 startActivity(sendIntent);

But I want to be able to send emojis (emoticons) to whatsapp through an intent.
How is it possible? Do we have some special codes for the emojis?

Answer 1

I used StringBuilder for this like:

int unicode = 0x1F600
StringBuilder s = new StringBuilder();
s.append("YOUR MESSAGE HERE");
s.append(Character.toChars(unicode));

The resulting string will be something like this

YOUR MESSAGE HERE😀

Copy the unicode from here But remember to change the code that you will copy from this webpage from U-1F600 to 0x1F600.

U-1F600 is the unicode but android doesn't recognizes this. 0x1F600 is the hexcode for android.
