Effective in 2026, to align with our trunk stable development model and ensure platform stability for the ecosystem, we will publish source code to AOSP in Q2 and Q4. For building and contributing to AOSP, use android-latest-release. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.

DeviceMetricData

public class DeviceMetricData
extends Object implements Serializable

java.lang.Object
↳	com.android.tradefed.device.metric.DeviceMetricData

Object to hold all the data collected by metric collectors. TODO: Add the data holding and receiving of data methods.

Summary

Public constructors
`DeviceMetricData(IInvocationContext context)` Ctor

Public methods
`void`	`addMetric(String key, MetricMeasurement.Metric.Builder metric)` Add a single metric associated with the primary device.
`void`	`addMetricForDevice(ITestDevice device, String key, MetricMeasurement.Metric.Builder metric)` Add a single metric associated with a specified device.
`void`	`addToMetrics(HashMap<String, MetricMeasurement.Metric> metrics)` Push all the data received so far to the map of metrics that will be reported.

Public constructors

DeviceMetricData

public DeviceMetricData (IInvocationContext context)

Ctor

Parameters
`context`	`IInvocationContext`

Public methods

addMetric

public void addMetric (String key, 
                MetricMeasurement.Metric.Builder metric)

Add a single metric associated with the primary device.

Parameters
`key`	`String`: The key of the metric.
`metric`	`MetricMeasurement.Metric.Builder`: The value associated with the metric.

addMetricForDevice

public void addMetricForDevice (ITestDevice device, 
                String key, 
                MetricMeasurement.Metric.Builder metric)

Add a single metric associated with a specified device.

Parameters
`device`	`ITestDevice`: the `ITestDevice` the metric is associated to.
`key`	`String`: The key of the metric.
`metric`	`MetricMeasurement.Metric.Builder`: The value associated with the metric.

addToMetrics

public void addToMetrics (HashMap<String, MetricMeasurement.Metric> metrics)

Push all the data received so far to the map of metrics that will be reported. This should also clean up the resources after pushing them.

Parameters
`metrics`	`HashMap`: The metrics currently available.
