2013-12-19Move some system services to separate directoriesAmith Yamasani
Refactored the directory structure so that services can be optionally excluded. This is step 1. Will be followed by another change that makes it possible to remove services from the build. Change-Id: Ideacedfd34b5e213217ad3ff4ebb21c4a8e73f85
2013-12-12Introduce a Lifecycle for system servicesAdam Lesinski
Provide an abstract class for system services to extend from, similar to the android.app.Service. This will allow services to receive events in a uniform way, and will allow services to be created and started in the correct order regardless of whether or not a particular service exists. Similar to android.app.Service, services are meant to implement Binder interfaces as inner classes. This prevents services from having incestuous access to each other and makes them use the public API. Change-Id: Iaacfee8d5f080a28d7cc606761f4624673ed390f
2013-08-07batteryservice: add battery current now and charge counter dataTodd Poynor
Available for retrieval via future APIs if desired. Dumped by dumpsys. Not added to batterystats or ACTION_BATTERY_CHANGED intents at this point. Also fixes a formatting problem in the existing dumpsys output for voltage. Change-Id: I5320b19035914256fb872c13095c09c648dd522a
2013-07-30BatteryService use IBatteryProperties interfaces, drop JNITodd Poynor
IBatteryPropertiesListener binder interface to deliver notifications of changed battery/power status from healthd system health daemon. healthd watches uevents from power_supply. Change-Id: I1ab38622baf28356a6627fe2354b77e2ef99d838
2013-07-12Reduce some event log noise:Dianne Hackborn
- Only log battery levels on level changes, not voltage or temp. - Reduce the text in the start service log to only the suffix of the service component, and a uid field. Change-Id: I6d65e6700e021b3b005dccc90d64f36c1f97137f
2013-06-26Work on issue #9586838: Crash after waking up Hammerhead deviceDianne Hackborn
I made the power manager more rigid, not allowing different uids to use the same wake lock. This never should happen. I would guess there is somewhere that the activity manager is acquiring the wake lock without clearing the calling identity... but it is hard to follow all the paths this may happen in. So here we add some checks when acquiring/releasing the wake lock to make sure it is being done as the system uid. Also: - Protect the new activity stack calls with a permission, and make sure to clear the calling uid once past that. - Collect uid data from process stats so we can correctly associate CPU use with a uid even if we don't know about the pid for some reason. - Fix battery stats dump commands to clear calling uid before executing so they aren't broken.

2013-06-24Use FastPrintWriter... everywhere.Dianne Hackborn
One problem this turned up is, because FastPrintWriter does its own buffering, a lot of code that used to use PrintWriter would fail -- if it pointed to a StringWriter, there was no buffering, so it could just immediately get the result. Now you need to first flush the FastPrintWriter. Also added some new constructors to specify the size of buffer that FastPrintWriter should use. Change-Id: If48cd28d7be0b6b3278bbb69a8357e6ce88cf54a
2013-05-06am b0675df8: am faa47b52: Merge "Idle maintenance scheduling broken." into ↵Svetoslav
jb-mr2-dev * commit 'b0675df8fd377230edc392e02ba0eba275b57992': Idle maintenance scheduling broken.
2013-05-03Idle maintenance scheduling broken.Svetoslav
1. The scheduling was relying on receiving battery level broadcasts which however are not sent if the device is asleep. The maintenance window was not bound and we could miss a frame if the user did not interact the device longer than the min time between two maintenance windows. 2. Hide the idle maintenance intents since this will be rewritten to user services. bug:8688454 Change-Id: I17b421b09823cb46ec218cabda19e02432d94f8c
2013-04-30Better --unplugged support when dumping battery.Jeff Sharkey

2012-10-05Fix a deadlock involving BatteryService.Jeff Brown
The PowerManager may call into the BatteryService while holding its locks. We need to be careful that the BatteryService doesn't call into other services, particularly the ActivityManager while holding its own locks. Bug: 7298218 Change-Id: Ibf8ab13224f204a9857825265e864f93583bce8e
2012-10-03Fix issue #7267494, issue #7212347Dianne Hackborn
7267494 Calendar is not syncing Check for whether a content provider is dead before returning it. This is kind-of a band-aid, but probably the right thing to do; I'm just not sure exactly the full details of why this problem is happening. Hopefully this "fixes" it, though I don't have a way to repro to tell. 7212347 System power off dialog is only visible to user 0 Make it visible. Also turn on some battery debugging stuff and clean it up so we can just keep it. Change-Id: I5add25bf2a763c8dfe1df23bc5c753a9ea5d157a
2012-10-02Implement screen on hack for wireless chargers.Jeff Brown
We can't accurately detect whether the device is resting on a wireless charger unless it is actually charging. So we need to tweak the screen on when plugged / unplugged policy accordingly to avoid spurious wakeups. Bug: 7234284 Change-Id: I624b559e2e92b8813b12090bc20eca5f5158997e

2012-08-30Improve multi-user broadcasts.Dianne Hackborn
You can now use ALL and CURRENT when sending broadcasts, to specify where the broadcast goes. Sticky broadcasts are now correctly separated per user, and registered receivers are filtered based on the requested target user. New Context APIs for more kinds of sending broadcasts as users. Updating a bunch of system code that sends broadcasts to explicitly specify which user the broadcast goes to. Made a single version of the code for interpreting the requested target user ID that all entries to activity manager (start activity, send broadcast, start service) use.

2010-08-31Revert "Shutdown when capacity is 0% and no charging or when battery is dead"Jean-Baptiste Queru
This reverts commit fd04143a47770256dabcfa4d8447127b3ec8b2bf. This break most automated tests because with this change, if the device is fully charged, it will simply turn off the screen, regardless if USB is connected to hsot PC or not; so for our tests, most of them are always connected to host PC, and fully charged 99% of the time, as soon as the screen turns off, the front-end test Activity will be suspended.

2010-08-26Shutdown when capacity is 0% and no charging or when battery is deadImre Sunyi
Android framework does not shutdown when battery capacity is 0% and a charger is attached (USB or AC). This handling is incomplete since a charger might very well be attached but charging has stopped because USB suspended or the charging algorithm has stopped because of battery safety handling. Also shutdown when battery is reported 'dead'. This might happen although charging is present. Change-Id: If328260ebf4d38f912e4d2fad204431cbb19c993
2010-06-16Various improvements to battery stats collectionDianne Hackborn
We now clear the battery stats when unplugging after the battery is full. This allows us to use the "total" stats as a new "since last charged" stat. Total is gone. I never used it, it was worthless. Since last charged is a lot more interesting. The battery history now collects a lot more stats, and keeps control over how much it can collect. Printing is now more descriptive. The kinds of stats have been renamed to SINCE_UNPLUGGED and SINCE_DISCHARGED. The other two stats are still there, but no longer printed; a future change will eliminate them completely along with all of their state. Change-Id: I4e9fcfcf8c30510092c76a8594f6021e9502fbc1

2009-12-14Implement API to have new broadcasts replace existing broadcasts.Dianne Hackborn
Use this in various places where it should serve no purpose to deliver both broadcasts. This is intended to reduce somewhat the flurry of broadcasts that we churn through during boot.
2009-12-04move event log tags used by system server into this packageDoug Zongker
We can now locate event log tag definitions in individual packages (and java constants for the tag numbers get auto-generated), so move all the tags used by the system server into the package.

2009-07-16Send all battery broadcasts with REGISTERED_ONLY_BEFORE_BOOTChristopher Tate

2009-04-07Fix issue #1769910 (Track activity launch times)Dianne Hackborn
The usage stats service now collects per-activity launch time stats. There are a number of fixes and improvements to its statistics management and collection; it now operates its calendar in GMT and ensures that for checkin purposes it always reports one day and only one complete day to the checkin service. Also change the checkin option from "-c" to "--checkin" since it is really a special thing.
