                 currentRunMetrics)

Callback when a test run is ended. This should be the time for clean up.

Parameters
`runData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the run. Will be the same object as during `BaseDeviceMetricCollector.onTestRunStart(com.android.tradefed.device.metric.DeviceMetricData)`.
`currentRunMetrics`	: the current map of metrics passed to `ERROR(/#testRunEnded(long,Map))`.

Throws
`DeviceNotAvailableException`

public void rebootEnded (ITestDevice device)

Gets notification when the reboot ended in device.

NOTE: Receivers should avoid rebooting during this callback. Any reboot attempt will be ignored.

Parameters
`device`	`ITestDevice`: `ITestDevice` where the reboot ended.

Throws
`DeviceNotAvailableException`

public void rebootStarted (ITestDevice device)

Gets notification when reboot started in device.
