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.

GoogleDeviceFlashPreparer

public class GoogleDeviceFlashPreparer
extends DeviceFlashPreparer implements IInvocationContextReceiver, ILabPreparer

java.lang.Object
↳	com.android.tradefed.targetprep.BaseTargetPreparer
	↳	com.android.tradefed.targetprep.DeviceFlashPreparer
		↳	com.google.android.tradefed.targetprep.GoogleDeviceFlashPreparer

A specialization of DeviceFlashPreparer that supports custom steps needed to flash Google devices.

It handles this by creating the appropriate IDeviceFlasher based on product type

Summary

Public constructors
`GoogleDeviceFlashPreparer()`

Public methods
`IBuildInfo`	`getBuild(TestInformation testInfo)` Wrap the getBuildInfo so we have a change to override it for specific scenarios.
`void`	`setAltStaticDeviceInfoClass(String altStaticDeviceInfoClass)`
`void`	`setInvocationContext(IInvocationContext invocationContext)`
`void`	`setUp(TestInformation testInfo)`

Protected methods
`void`	`checkDeviceProductType(ITestDevice device, IDeviceBuildInfo deviceBuild)` Possible check before flashing to ensure the device is as expected compare to the build info.
`IDeviceFlasher`	`createFlasher(ITestDevice device)` Create `IDeviceFlasher` to use
`FlashingResourcesRetrieverCacheWrapper`	`createFlashingResources(String productType)`
