MemoryInfo

Kotlin |Java

open class MemoryInfo : Parcelable

kotlin.Any
↳	android.app.ActivityManager.MemoryInfo

Information you can retrieve about the available memory through ActivityManager#getMemoryInfo.

Summary

Inherited constants

From class Parcelable

Int

CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int

PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Public constructors
`<init>()`

Public methods
open Int	`describeContents()`
open Unit	`readFromParcel(source: Parcel!)`
open Unit	`writeToParcel(dest: Parcel!, flags: Int)`

Properties
static Parcelable.Creator<ActivityManager.MemoryInfo!>	`CREATOR`
Long	`availMem` The available memory on the system.
Boolean	`lowMemory` Set to true if the system considers itself to currently be in a low memory situation.
Long	`threshold` The threshold of `availMem` at which we consider memory to be low and start killing background services and other non-extraneous processes.
Long	`totalMem` The total memory accessible by the kernel.

MemoryInfo()

Public methods

describeContents

Added in API level 1

open fun describeContents(): Int

Return
`Int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR`

readFromParcel

Added in API level 1

open fun readFromParcel(source: Parcel!): Unit

writeToParcel

Added in API level 1

open fun writeToParcel(
    dest: Parcel!, 
    flags: Int
): Unit

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`. Value is either `0` or a combination of `android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES

Properties

CREATOR

Added in API level 1

static val CREATOR: Parcelable.Creator<ActivityManager.MemoryInfo!>

availMem

Added in API level 1

var availMem: Long

The available memory on the system. This number should not be considered absolute: due to the nature of the kernel, a significant portion of this memory is actually in use and needed for the overall system to run well.

lowMemory

Added in API level 1

var lowMemory: Boolean

Set to true if the system considers itself to currently be in a low memory situation.

threshold

Added in API level 1

var threshold: Long

The threshold of availMem at which we consider memory to be low and start killing background services and other non-extraneous processes.

totalMem

Added in API level 16

var totalMem: Long

The total memory accessible by the kernel. This is basically the RAM size of the device, not including below-kernel fixed allocations like DMA buffers, RAM for the baseband CPU, etc.
