EMPTY_STRING_ARRAY
final ArrayList
mHistory
The back history of all previous (and possibly still running) activities. It contains HistoryRecord objects.
final ArrayList
mParallelBroadcasts
List of all active broadcasts that are to be executed immediately (without waiting for another broadcast to finish). Currently this only contains broadcasts to registered receivers, to avoid spinning up a bunch of processes to execute IntentReceiver components.
final ArrayList
mOrderedBroadcasts
List of all active broadcasts that are to be executed one at a time. The object at the top of the list is the currently activity broadcasts; those after it are waiting for the top to finish..
boolean
mBroadcastsScheduled
Set when we current have a BROADCAST_INTENT_MSG in flight.
boolean
mUserLeaving
Set to indicate whether to issue an onUserLeaving callback when a newly launched activity is being brought in front of us.
HistoryRecord
mPausingActivity
When we are in the process of pausing an activity, before starting the next one, this variable holds the activity that is currently being paused.
HistoryRecord
mResumedActivity
Current activity that is resumed, or null if there is none.
HistoryRecord
mFocusedActivity
Activity we have told the window manager to have key focus.
HistoryRecord
mLastPausedActivity
This is the last activity that we put into the paused state. This is used to determine if we need to do an activity transition while sleeping, when we normally hold the top activity paused.
final ArrayList
mWaitingVisibleActivities
List of activities that are waiting for a new activity to become visible before completing whatever operation they are supposed to do.
final ArrayList
mStoppingActivities
List of activities that are ready to be stopped, but waiting for the next activity to settle down before doing so. It contains HistoryRecord objects.
final ArrayList
mRecentTasks
List of intents that were used to start the most recent tasks.
final ArrayList
mFinishingActivities
List of activities that are ready to be finished, but waiting for the previous activity to settle down before doing so. It contains HistoryRecord objects.
final com.android.server.ProcessMap
mProcessNames
All of the applications we currently have running organized by name. The keys are strings of the application package name (as returned by the package manager), and the keys are ApplicationRecord objects.
final com.android.server.ProcessMap
mProcessCrashTimes
The last time that various processes have crashed.
final com.android.server.ProcessMap
mBadProcesses
Set of applications that we consider to be bad, and will reject incoming broadcasts from (which the user has no control over). Processes are added to this set when they have crashed twice within a minimum amount of time; they are removed from it when they are later restarted (hopefully due to some user action). The value is the time it was added to the list.
final android.util.SparseArray
mPidsSelfLocked
All of the processes we currently have running organized by pid. The keys are the pid running the application.

NOTE: This object is protected by its own lock, NOT the global activity manager lock!

final android.util.SparseArray
mForegroundProcesses
final ArrayList
mProcessesOnHold
List of records for processes that someone had tried to start before the system was ready. We don't start them at that point, but ensure they are started by the time booting is complete.
final ArrayList
mStartingProcesses
List of records for processes that we have started and are waiting for them to call back. This is really only needed when running in single processes mode, in which case we do not have a unique pid for each process.
final ArrayList
mPersistentStartingProcesses
List of persistent applications that are in the process of being started.
final ArrayList
mRemovedProcesses
Processes that are being forcibly torn down.
final ArrayList
mLRUProcesses
List of running applications, sorted by recent usage. The first entry in the list is the least recently used. It contains ApplicationRecord objects. This list does NOT include any persistent application records (since we never want to exit them).
final ArrayList
mProcessesToGc
List of processes that should gc as soon as things are idle.
private ProcessRecord
mHomeProcess
This is the process holding what we currently consider to be the "home" activity.
private final ArrayList
mLRUActivities
List of running activities, sorted by recent usage. The first entry in the list is the least recently used. It contains HistoryRecord objects.
final HashSet
mPendingResultRecords
Set of PendingResultRecord objects that are currently active.
final HashMap
mIntentSenderRecords
Set of IntentSenderRecord objects that are currently active.
BroadcastRecord
mPendingBroadcast
Intent broadcast that we have tried to start, but are waiting for its application's process to be created. We only need one (instead of a list) because we always process broadcasts one at a time, so no others can be started while waiting for this one.
final HashMap
mRegisteredReceivers
Keeps track of all IIntentReceivers that have been registered for broadcasts. Hash keys are the receiver IBinder, hash value is a ReceiverList.
final com.android.server.IntentResolver
mReceiverResolver
Resolver for broadcast intents to registered receivers. Holds BroadcastFilter (subclass of IntentFilter).
final HashMap
mStickyBroadcasts
State of all active sticky broadcasts. Keys are the action of the sticky Intent, values are an ArrayList of all broadcasted intents with that action (which should usually be one).
final HashMap
mServices
All currently running services.
final HashMap
mServicesByIntent
All currently running services indexed by the Intent used to start them.
final HashMap
mServiceConnections
All currently bound service connections. Keys are the IBinder of the client's IServiceConnection.
final ArrayList
mPendingServices
List of services that we have been asked to start, but haven't yet been able to. It is used to hold start requests while waiting for their corresponding application thread to get going.
final ArrayList
mRestartingServices
List of services that are scheduled to restart following a crash.
final ArrayList
mStoppingServices
List of services that are in the process of being stopped.
final ArrayList
mPendingThumbnails
List of PendingThumbnailsRecord objects of clients who are still waiting to receive all of the thumbnails for a task.
final ArrayList
mCancelledThumbnails
List of HistoryRecord objects that have been finished and must still report back to a pending thumbnail receiver.
final HashMap
mProvidersByName
All of the currently running global content providers. Keys are a string containing the provider name and values are a ContentProviderRecord object containing the data about it. Note that a single provider may be published under multiple names, so there may be multiple entries here for a single one in mProvidersByClass.
final HashMap
mProvidersByClass
All of the currently running global content providers. Keys are a string containing the provider's implementation class and values are a ContentProviderRecord object containing the data about it.
final ArrayList
mLaunchingProviders
List of content providers who have clients waiting for them. The application is currently being launched and the provider will be removed from this list once it is published.
private final android.util.SparseArray
mGrantedUriPermissions
Global set of specific Uri permissions that have been granted.
private static ThreadLocal
sCallerIdentity
final BatteryStatsService
mBatteryStatsService
All information we have collected about the runtime performance of any user id that can impact battery performance.
final UsageStatsService
mUsageStatsService
information about component usage
android.content.res.Configuration
mConfiguration
Current configuration information. HistoryRecord objects are given a reference to this object to indicate which configuration they are currently running in, so this object must be kept immutable.
HashMap
mAppBindArgs
List of initialization arguments to pass to all processes when binding applications to them. For example, references to the commonly used services.
boolean
mStartRunning
Used to control how we initialize the service.
android.content.ComponentName
mTopComponent
String
mTopAction
String
mTopData
boolean
mSystemReady
boolean
mBooting
android.content.Context
mContext
int
mFactoryTest
boolean
mSleeping
Set while we are wanting to sleep, to prevent any activities from being started/resumed.
PowerManager.WakeLock
mGoingToSleep
Set when the system is going to sleep, until we have successfully paused the current activity and released our wake lock. At that point the system is allowed to actually sleep.
PowerManager.WakeLock
mLaunchingActivity
We don't want to allow the device to go to sleep while in the process of launching an activity. This is primarily to allow alarm intent receivers to launch an activity and get that to run before the device goes back to sleep.
int
mCurTask
Task identifier that activities are currently being started in. Incremented each time a new task is created. todo: Replace this with a TokenSpace class that generates non-repeating integers that won't wrap.
int
mAdjSeq
Current sequence id for oom_adj computation traversal.
boolean
mSimpleProcessManagement
Set to true if the ANDROID_SIMPLE_PROCESS_MANAGEMENT envvar is set, indicating the user wants processes started in such a way that they can use ANDROID_PROCESS_WRAPPER and know what will be running in each process (thus no pre-initialized process, etc).
int[]
mProcDeaths
System monitoring: number of processes that died since the last N procs were started.
String
mDebugApp
boolean
mWaitForDebugger
boolean
mDebugTransient
String

Callback of last caller to {@link #requestPss}.
final ArrayList
mRequestPssList
Remaining processes for which we are waiting results from the last call to {@link #requestPss}.
final Thread
mProcessStatsThread
Runtime statistics collection thread. This object's lock is used to protect all related state.
