ActivityManager.MemoryInfo

public static class ActivityManager.MemoryInfo
extends Object implements Parcelable

java.lang.Object
   ↳ android.app.ActivityManager.MemoryInfo


Information you can retrieve about the available memory through ActivityManager.getMemoryInfo(ActivityManager.MemoryInfo).

Summary

Inherited constants

Fields

public static final Creator<ActivityManager.MemoryInfo> CREATOR

public long availMem

The available memory on the system.

public boolean lowMemory

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

public long threshold

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

public long totalMem

The total memory accessible by the kernel.

Public constructors

ActivityManager.MemoryInfo()

Public methods

int describeContents()

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

void readFromParcel(Parcel source)
void writeToParcel(Parcel dest, int flags)

Flatten this object in to a Parcel.

Fields

CREATOR

added in API level 1
public static final Creator<ActivityManager.MemoryInfo> CREATOR

availMem

added in API level 1
public long availMem

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
public boolean lowMemory

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

threshold

added in API level 1
public long threshold

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
public long totalMem

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.

Public constructors

ActivityManager.MemoryInfo

added in API level 1
public ActivityManager.MemoryInfo ()

Public methods

describeContents

added in API level 1
public int describeContents ()

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(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

readFromParcel

added in API level 1
public void readFromParcel (Parcel source)

Parameters
source Parcel

writeToParcel

added in API level 1
public 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.PARCELABLE_WRITE_RETURN_VALUE.
