DeviceTraceCollector

public DeviceTraceCollector ()

Public methods

extraInit

public void extraInit (IInvocationContext context, 
                ITestInvocationListener listener)

Throws
DeviceNotAvailableException

onTestEnd

public void onTestEnd (DeviceMetricData testData, 
                 currentTestCaseMetrics)

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

Parameters
testData	DeviceMetricData: the DeviceMetricData holding the data for the test case. Will be the same object as during onTestStart(com.android.tradefed.device.metric.DeviceMetricData).
currentTestCaseMetrics	: the current map of metrics passed to ERROR(/#testEnded(com.android.tradefed.result.TestDescription,Map)).

Throws
DeviceNotAvailableException

onTestRunEnd

public void onTestRunEnd (DeviceMetricData runData, 
                 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

onTestStart

public void onTestStart (DeviceMetricData testData)

Callback when a test case is started.

Parameters
testData	DeviceMetricData: the DeviceMetricData holding the data for the test case.

Throws
DeviceNotAvailableException

rebootEnded

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

rebootStarted

public void rebootStarted (ITestDevice device)

Gets notification when reboot started in device.

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

Parameters
device	ITestDevice: ITestDevice where the reboot started.

Throws
DeviceNotAvailableException

setInstrumentationPkgName

public void setInstrumentationPkgName (String packageName)

Parameters
packageName	String
