Android drawText including text wrapping

Yes, StaticLayout is what you're meant to use to draw multi-line text on a Canvas. Save yourself a world of pain and don't think about breaking text yourself -- you're on the right path.

I'm not sure about the bitmap problem, but your second code above worked just fine to draw text on a canvas for me.

Learn to use StaticLayout , then draw the Layout object onto a canvas using the Layout.draw() method.

You should handle it yourself, calculating the text size and wrapping the content in some way (break line at max width or wrap last word).

I already did it on Java SE with the FontMetrics, never for Android; but you should take a look:

As pointed by Lisa, StaticLayout is the way to go to measure text wrapping.
