Fields

public static final Creator < ActivityManager.MemoryInfo > CREATOR

Added in API level 1

public long availMem

Added in API level 1

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.

public boolean lowMemory

Added in API level 1

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

public long threshold

Added in API level 1

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

Added in API level 16

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

public ActivityManager.MemoryInfo ()

Added in API level 1

Public Methods

public int describeContents ()

Added in API level 1

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

Returns
  • a bitmask indicating the set of special object types marshalled by the Parcelable.

public void readFromParcel ( Parcel source)

Added in API level 1

public void writeToParcel ( Parcel dest, int flags)

Added in API level 1

Flatten this object in to a Parcel.

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