Share generated image

Question

Hello, everyone, I’m new to the forum but whenever I can I follow some topics.

I have an Android application where it generates a bitmap and I would like to share this bitmap via Whatsapp or email but I’ve been cracking heads, if anyone can help me would be very grateful.

Follows Java code class where I put the code:

package br.com.codeapp.kcode;

import android.content.Intent;

import android.graphics.drawable.BitmapDrawable;
