getPowerMonitorReadings

Added in API level VanillaIceCream
open fun getPowerMonitorReadings(
    powerMonitors: MutableList<PowerMonitor!>, 
    executor: Executor?, 
    onResult: OutcomeReceiver<PowerMonitorReadings!, RuntimeException!>
): Unit

Asynchronously retrieves the accumulated power consumption reported by the specified power monitors.

Parameters
powerMonitors MutableList<PowerMonitor!>: power monitors to be retrieved. This value cannot be null.
executor Executor?: optional Executor to deliver the callbacks. If not supplied, the callback may be invoked on an arbitrary thread. This value may be null.
onResult OutcomeReceiver<PowerMonitorReadings!, RuntimeException!>: callback for the result This value cannot be null.

getSupportedPowerMonitors

Added in API level VanillaIceCream
open fun getSupportedPowerMonitors(
    executor: Executor?, 
    onResult: Consumer<MutableList<PowerMonitor!>!>
): Unit

Asynchronously retrieves a list of supported PowerMonitor's, which include raw ODPM (on-device power rail monitor) rails and modeled energy consumers. If ODPM is unsupported on this device this method delivers an empty list.

Parameters
executor Executor?: optional Handler to deliver the callback. If not supplied, the callback may be invoked on an arbitrary thread. This value may be null.
onResult Consumer<MutableList<PowerMonitor!>!>: callback for the result This value cannot be null.

takeMyUidSnapshot

Added in API level 24
open fun takeMyUidSnapshot(): HealthStats!

Return a HealthStats object containing a snapshot of system health metrics for the application calling this API. This method is the same as calling takeUidSnapshot(Process.myUid()).

Return
HealthStats! A HealthStats object containing the metrics for this application. The keys for this HealthStats object will be from the UidHealthStats class.

takeUidSnapshot

Added in API level 24
open fun takeUidSnapshot(uid: Int): HealthStats!

Return a HealthStats object containing a snapshot of system health metrics for the given uid (user-id, which in usually corresponds to application).

Parameters
uid Int: User ID for a given application.
Return
HealthStats! A HealthStats object containing the metrics for the requested application. The keys for this HealthStats object will be from the UidHealthStats class.

takeUidSnapshots

Added in API level 24
open fun takeUidSnapshots(uids: IntArray!): Array<HealthStats!>!

Return a HealthStats object containing a snapshot of system health metrics for the given uids (user-id, which in usually corresponds to application).

Parameters
uids IntArray!: An array of User IDs to retrieve.
Return
Array<HealthStats!>! An array of HealthStats objects containing the metrics for each of the requested uids. The keys for this HealthStats object will be from the UidHealthStats class.
