In this example we will learn how to programatically write text/paste image on an Image in Android . Before beginning with the example lets clear some basics
What is Bitmap Image in Android ?
A Bitmap image is a series of tiny dots(called pixels) which are arranged in a pattern to form an Image. Each pixel is a small square assigned with a color. You can actually see this square pixel when you extra zoom into a image. The whole image can be edited by erasing or changing colors of individual pixels using different software tools. Android also allows us to work on Bitmaps with the help of various APIs.
