A PowerMonitor represents either an ODPM rail (on-device power rail monitor) or a modeled energy consumer.
ODPM rail names are device-specific. No assumptions should be made about the names and exact purpose of ODPM rails across different device models. A rail name may be something like "S2S_VDD_G3D"; specific knowledge of the device hardware is required to interpret the corresponding power monitor data. Energy consumer have more human-readable names, e.g. "GPU", "MODEM" etc. However, developers must be extra cautious about using energy consumers across different device models, as their exact implementations are also hardware dependent and are customized by OEMs.Summary

Constants
POWER_MONITOR_TYPE_CONSUMER
public static final int POWER_MONITOR_TYPE_CONSUMER
Power monitor corresponding to a subsystem. The energy value may be a direct pass-through power rail measurement, or modeled in some fashion. For example, an energy consumer may represent a combination of multiple rails or a portion of a rail shared between subsystems, e.g. WiFi and Bluetooth are often handled by the same chip, powered by a shared rail. Some consumer names are standardized, others are not.
Constant Value: 0 (0x00000000)
POWER_MONITOR_TYPE_MEASUREMENT
public static final int POWER_MONITOR_TYPE_MEASUREMENT
Power monitor corresponding to a directly measured power rail. Rails are device-specific: no assumptions can be made about the source of those measurements across different devices, even if they have the same name.
Constant Value: 1 (0x00000001)
Fields
Public methods
describeContents
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 |
getName
public String getName ()
Returns the name of the power monitor, either a power rail or an energy consumer.
Returns | |
---|---|
String |
This value cannot be null . |
getType
public int getType ()
Returns the type of the power monitor.
Returns | |
---|---|
int |
Value is either 0 or a combination of POWER_MONITOR_TYPE_CONSUMER , and POWER_MONITOR_TYPE_MEASUREMENT |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel : This value cannot be null . |
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 |
