int dalvikPrivateDirty
The private dirty pages used by dalvik heap.
int dalvikPss
The proportional set size for dalvik heap. (Doesn't include other Dalvik overhead.)
int dalvikSharedDirty
The shared dirty pages used by dalvik heap.
int nativePrivateDirty
The private dirty pages used by the native heap.

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. |
String getMemoryStat (String statName)
