One more tip - I got the best bang for the buck by reducing the
footprints of bitmaps and canvases. Mine were unnecessarily big, at
first.

I've seen crashes like this (did not take snapshots of the traces to
compare) as well. If I remember correctly, the built-in Map app can be
crashed like that, too. Just as your trace shows, this occurs mostly
in animateTo(). I suspected this had to do with memory availability
(or lack thereof) when new tiles are loaded, so I spent a few days on
optimizing memory usage on my end. I found the problem tapered off
considerably after that campaign. When testing, I have to try pretty
hard now to trigger this (on a standard G1 or emulator session).

Hi ,
I have from time to time some crashes on the google code for drawing
tiles on a mapActivity.

Any idea what could cause such crashes and how to avoid/prevent them
