I have a background service that gets data from somewhere and likes to draw to a canvas.
The service creates a Canvas object and use the draw primitives on it from the service.
Does Android allow that?
Thanks
Background services don’t interact with UI. If you’re looking to show something to the user, you could instead have the service fetch the data, and notify an activity that draws. That said, I don’t see why a service can’t interact with a Canvas object as long as you’re not displaying it. If you’re just drawing on it and then writing to disk for example, I believe it should be technically possible.
