I'm trying to find some official android documentation that discusses
sleep mode, with a focus on issues that might be of relevance to app
developers.   For example, things like:

1. What causes a device to enter / exit sleep mode?

2. How are running processes impacted when the device enters sleep
mode?  (I believe they continue to exist, but don't execute because
cpu activity is suspended.  When the device wakes up execution picks
up where it left off?)

There is some good info in the API docs for PowerManager and WakeLock,
but nothing there that explicitly states what I have assumed in point
2 above.

Are the above issues (and any other relevant issues) documented
anywhere?

Cheers ...

Lack of user input.

They freeze in place, picking up when the CPU starts up again.

Not really, AFAIK.

One thing I've noticed on froyo, and this could be due to my lack of
understanding, is that network connections sometimes fail over wifi even
with cpu and wifi lock. Wifi reports its connected yet calls fail
immediately. The second I wake up the phone, back in business. (if I disable
wifi and re-try, works fine over 3G)
