Creating an empty bitmap and drawing though canvas in Android

Question

I'd like to create an empty bitmap and set a canvas to that bitmap and then draw any shape on the bitmap.

Answer 1

This is probably simpler than you're thinking:

int w = WIDTH_PX, h = HEIGHT_PX;  Bitmap.Config conf = Bitmap.Config.ARGB_8888; // see other conf types Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap Canvas canvas = new Canvas(bmp);  // ready to draw on that bitmap through that canvas 

Here's a series of tutorials I've found on the topic: Drawing with Canvas Series
