Canvas Size Limitations?

Do you mean size of drawing a circle?

Please precise.

No, I mean drawable canvas size limitations. Because I need a drawable canvas 8 times bigger than the screen size.
But my app force closes. I checked the log and there was an error entry containing the term "out of memory"
So what is the limit of canvas size?

And does it change phone to phone?

There is no hard limit for the canvas maximum size. It depends on the process available memory (which is much smaller than the device available memory).

You should instead create a much smaller bitmap and when you draw it to the activity you should resize the drawing area (like a digital zoom).
