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
`MemoryInfo()`

Public methods
open Int	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
open Unit	`readFromParcel(source: Parcel!)`
open Unit	`writeToParcel(dest: Parcel, flags: Int)` Flatten this object in to a Parcel.

Properties
static Parcelable.Creator<ActivityManager.MemoryInfo!>	`CREATOR`
Long	`advertisedMem` The advertised memory of the system, as the end user would encounter in a retail display environment.
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

Added in API level 1

MemoryInfo()

Public methods

describeContents

Added in API level 1

open fun describeContents(): Int

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel,int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

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

Flatten this object in to a Parcel.

Parameters
`dest`	Parcel: The Parcel in which the object should be written. This value cannot be `null`.
`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 the following: `PARCELABLE_WRITE_RETURN_VALUE`

Properties

CREATOR

Added in API level 1

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

advertisedMem

Added in API level 34

var advertisedMem: Long

The advertised memory of the system, as the end user would encounter in a retail display environment. This value might be different from totalMem. This could be due to many reasons. For example, the ODM could reserve part of the memory for the Trusted Execution Environment (TEE) which the kernel doesn't have access or knowledge about it.

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.
