How to programmatically send a emoji image to Whatsapp App on Android?

Question

Whatsapp's Android documentation explains how to send text and images as messages but I can't find anything about setting a new emoji image into WhatsApp.

I have downloaded a sticker/emoji creation app on my Android phone. After creating a new memoji, it shows a "Add to WhatsApp" button. I suspect it sends some Intent to WhatsApp, then WhatsApp would show a confirmation to the user about adding the Memoji. Once confirmed, the memoji is added to the Whatsapp keyboard. I haven't seen such Intent documented so want to know what Intent it may be.

You can use StringBuilder like this:

int smilingFaceUnicode = 0x1F60A; //U+1F60A

StringBuilder sb = new StringBuilder();
sb.append("Hello everyone ");
sb.append(Character.toChars(smilingFaceUnicode));

Result :

Hello everyone

You can search your emoji character with unicode in the link below. https://unicode.org/emoji/charts/full-emoji-list.html
