Thanks Chris. My issue with startup performance is from when I tap the
application to when I get my first chance to run code. Once I get my first
OnCreate() call on my SplashActivity, I do utilize background threads and
and IoC container, but it's loading the runtime that's the problem.
I know there'll be a lag, and I've seen 2-3secs quoted, but that's
optimistic. On my device (2 year old HTC legend running Android 2.2), it's
5-10 secs. (sample log extract below)
