Original Image

Masked Image (Needs to create like this)

From the above original image I have to mask the dog and create it as a bitmap or png

You need to make a custom view which support draw line, make custom view background be transparent. Then put that view on top the ImageView in your layout. And after drawed the mask, just save the drawing bitmap create from custom view.
