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.
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. 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 MemoryInfo ()
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(android.os.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.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
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 .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
