int IMPORTANCE_TOP_SLEEPING

Constant for importance: This process is running the foreground UI, but the device is asleep so it is not visible to the user.

Constants

IMPORTANCE_BACKGROUND

Added in API level 3
int IMPORTANCE_BACKGROUND

Constant for importance: This process process contains background code that is expendable.

Constant Value: 400 (0x00000190)

IMPORTANCE_EMPTY

Added in API level 3
int IMPORTANCE_EMPTY

Constant for importance: This process is empty of any actively running code.

Constant Value: 500 (0x000001f4)

IMPORTANCE_FOREGROUND

Added in API level 3
int IMPORTANCE_FOREGROUND

Constant for importance: This process is running the foreground UI; that is, it is the thing currently at the top of the screen that the user is interacting with.

Constant Value: 100 (0x00000064)

IMPORTANCE_FOREGROUND_SERVICE

Added in API level 23
int IMPORTANCE_FOREGROUND_SERVICE

Constant for importance: This process is running a foreground service, for example to perform music playback even while the user is not immediately in the app. This generally indicates that the process is doing something the user actively cares about.

Constant Value: 125 (0x0000007d)

IMPORTANCE_GONE

Added in API level 21
int IMPORTANCE_GONE

Constant for importance: This process does not exist.

Constant Value: 1000 (0x000003e8)

IMPORTANCE_PERCEPTIBLE

Added in API level 9
int IMPORTANCE_PERCEPTIBLE

Constant for importance: This process is not something the user is directly aware of, but is otherwise perceptable to them to some degree.

Constant Value: 130 (0x00000082)

IMPORTANCE_SERVICE

Added in API level 3
int IMPORTANCE_SERVICE

Constant for importance: This process is contains services that should remain running. These are background services apps have started, not something the user is aware of, so they may be killed by the system relatively freely (though it is generally desired that they stay running as long as they want to).

Constant Value: 300 (0x0000012c)

IMPORTANCE_TOP_SLEEPING

Added in API level 23
int IMPORTANCE_TOP_SLEEPING

Constant for importance: This process is running the foreground UI, but the device is asleep so it is not visible to the user. This means the user is not really aware of the process, because they can not see or interact with it, but it is quite important because it what they expect to return to once unlocking the device.

Constant Value: 150 (0x00000096)

IMPORTANCE_VISIBLE

Added in API level 3
int IMPORTANCE_VISIBLE

Constant for importance: This process is running something that is actively visible to the user, though not in the immediate foreground. This may be running a window that is behind the current foreground (so paused and with its state saved, not interacting with the user, but visible to them to some degree); it may also be running other services under the system's control that it inconsiders important.

Constant Value: 200 (0x000000c8)

REASON_PROVIDER_IN_USE

Added in API level 5
int REASON_PROVIDER_IN_USE

Constant for importanceReasonCode: one of the application's content providers is being used by another process. The pid of the client process is in importanceReasonPid and the target provider in this process is in importanceReasonComponent.

Constant Value: 1 (0x00000001)

REASON_SERVICE_IN_USE

Added in API level 5
int REASON_SERVICE_IN_USE

Constant for importanceReasonCode: one of the application's content providers is being used by another process. The pid of the client process is in importanceReasonPid and the target provider in this process is in importanceReasonComponent.

Constant Value: 2 (0x00000002)

REASON_UNKNOWN

Added in API level 5
int REASON_UNKNOWN

Constant for importanceReasonCode: nothing special has been specified for the reason for this level.

Constant Value: 0 (0x00000000)

Fields

importance

Added in API level 3
int importance

The relative importance level that the system places on this process. May be one of IMPORTANCE_FOREGROUND, IMPORTANCE_VISIBLE, IMPORTANCE_SERVICE, IMPORTANCE_BACKGROUND, or IMPORTANCE_EMPTY. These constants are numbered so that "more important" values are always smaller than "less important" values.

importanceReasonCode

Added in API level 5
int importanceReasonCode

The reason for importance, if any.

importanceReasonComponent

Added in API level 5
ComponentName importanceReasonComponent

For the specified values of importanceReasonCode, this is the name of the component that is being used in this process.

importanceReasonPid

Added in API level 5
int importanceReasonPid

For the specified values of importanceReasonCode, this is the process ID of the other process that is a client of this process. This will be 0 if no other process is using this one.

lastTrimLevel

Added in API level 16
int lastTrimLevel

Last memory trim level reported to the process: corresponds to the values supplied to ComponentCallbacks2.onTrimMemory(int).

lru

Added in API level 3
int lru

An additional ordering within a particular importance category, providing finer-grained information about the relative utility of processes within a category. This number means nothing except that a smaller values are more recently used (and thus more important). Currently an LRU value is only maintained for the IMPORTANCE_BACKGROUND category, though others may be maintained in the future.

pid

Added in API level 3
int pid

The pid of this process; 0 if none

pkgList

Added in API level 3
String[] pkgList

All packages that have been loaded into the process.

processName

Added in API level 3
String processName

The name of the process that this object is associated with

uid

Added in API level 5
int uid

The user id of this process.

Public constructors

ActivityManager.RunningAppProcessInfo

Added in API level 3
ActivityManager.RunningAppProcessInfo ()

ActivityManager.RunningAppProcessInfo

Added in API level 3
ActivityManager.RunningAppProcessInfo (String pProcessName,

                String[] pArr)

Parameters
pProcessName String
pPid int
pArr String

Public methods

describeContents

Added in API level 3
int describeContents ()

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

Returns

Parameters
source Parcel

writeToParcel

Added in API level 3
void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written.
flags int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
