Thanks Yusuf. That's helpful - I am very familiar with that documentation. I was looking for something more though. I'm hoping to see a more comprehensive discussion about this behavior. I need to put together something for QA testers. No state can be left un- described for what I need.
And thank you Dianne. As always - a big help. This makes sense. What's not complete on my list, though is how a dark screen, phone components, and wake locks relate. I am not just looking for documentation on DIM wake lock and full wake lock. There are additional use cases here: * menu lock on/off (must press the menu button): what affects that? How do wake locks affect that? * dark screen versus a fully functional phone: for the complete list of sensors and application services (e.g TelephonyService notification to my TelephonyListener, Wifi antenna, and sensors), how do wake locks affect each one? When does each one get turned off? * how do each power state affect Timer class objects and application threads - for both foreground apps and background services? * when the user forces the screen to go dark by pressing the end-call button, what power state/wake lock state am I in? * when the application forces the screen to go dark by calling PowerManager. I also have the following case that I need to prove is working properly: 1. A RTC clock alarm fires an intent and wakes up the phone. 2. The application catches the intent and gets a wake lock. A background service is ran (no UI involved). 3. The wake lock is a dim wake lock, but the screen doesn't come on (that great). 4. The application does its processing then releases the wake lock(s) it acquired when responding to the intent. I believe it is. The more comprehensive information I'm looking proves it.....
