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, we recommend utilizing android-latest-release instead of aosp-main. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.

FastbootUpdateBootstrapPreparer

public class FastbootUpdateBootstrapPreparer
extends DeviceFlashPreparer

java.lang.Object
↳	com.android.tradefed.targetprep.BaseTargetPreparer
	↳	com.android.tradefed.targetprep.DeviceFlashPreparer
		↳	com.android.tradefed.targetprep.FastbootUpdateBootstrapPreparer

An ITargetPreparer that stages specified files (bootloader, radio, device image zip) into IDeviceBuildInfo to get devices flashed with FastbootDeviceFlasher, then injects post-boot device attributes into the build info for result reporting purposes.

This is useful for using fastboot update as device image update mechanism from externally sourced devices and builds, to fit into existing automation infrastructure.
