before the native canvas instance was created. If the canvas constructors throw an exception (because the bitmap passed in is immutable or already recycled), the constructor terminates early without allocating the native canvas instance. For the most part, that's okay, since the Canvas instance will never be returned to the application. However, the GC will still call finalize() on the half-initialized Canvas. The native methods for Canvas all assume that the canvas pointer passed down is not null.
