Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

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`.
