I apologize if this is a duplicate post. I am in need of some additional information on PowerManager, and I've seen several posts dealing with the issue, but still haven't found the specific information I need. Related links are below.
When the screen goes dark, it looks like the file subsystem becomes unavailable to the CPU. File I/O through a DataInputStream/DataOutputStream generates IOExceptions, even if the thread executing the calls to the file system completes fine. A FULL_WAKE_LOCK solves the problem, and a PARTIAL_WAKE_LOCK allows the file I/O to fail. Can anyone provide me more information about how a particular wake lock preserves the availability of each subsystem (e.g. File I/O, GPS, WI-FI notifications, etc.). I know this behavior is defined in the PowerManager, which in turn is relying on the Linux power management module (so, each phone will have different behavior potentially).
