For animations you can use
overridePendingTransition(0, 0); which I think is more reliable than the
Intent flag.
http://developer.android.com/reference/android/app/Activity.html#overridePendingTransition(int,
int)
Do it right before the startActivity
As for when to start the activity you might have luck creating a handler
and just posting a runnable to it in onCreate. I've done this in
transparent activities to avoid a brief black screen.
