When using the VSDK, dexopt is not applied during the vendor build. To avoid a first-boot time regression, dexopt is applied during the merge stage, by running dexopt on the vendor apps and rebuilding the vendor image. Bug: 188179859 Test: Tested in keystone with VSDK target Change-Id: Ie8e2d0a82850a2901fa6f250433bcbb43f0a97f2

"""This script merges two partial target files packages.
|
|
|
|
One input package contains framework files, and the other contains vendor files.
|
|
|
|
This script produces a complete, merged target files package:
|
|
- This package can be used to generate a flashable IMG package.
|
|
See --output-img.
|
|
- This package can be used to generate an OTA package. See --output-ota.
|
|
- The merged package is checked for compatibility between the two inputs.
|
|
|
|
Usage: merge_target_files [args]
|
|
|
|
--framework-target-files framework-target-files-zip-archive
|
|
The input target files package containing framework bits. This is a zip
|
|
archive.
|
|
|
|
--framework-item-list framework-item-list-file
|
|
The optional path to a newline-separated config file that replaces the
|
|
contents of DEFAULT_FRAMEWORK_ITEM_LIST if provided.
|
|
|
|
--framework-misc-info-keys framework-misc-info-keys-file
|
|
The optional path to a newline-separated config file that replaces the
|
|
contents of DEFAULT_FRAMEWORK_MISC_INFO_KEYS if provided.
|
|
|
|
--vendor-target-files vendor-target-files-zip-archive
|
|
The input target files package containing vendor bits. This is a zip
|
|
archive.
|
|
|
|
--vendor-item-list vendor-item-list-file
|
|
The optional path to a newline-separated config file that replaces the
|
|
contents of DEFAULT_VENDOR_ITEM_LIST if provided.
|
|
|
|
--output-target-files output-target-files-package
|
|
If provided, the output merged target files package. Also a zip archive.
|
|
|
|
--output-dir output-directory
|
|
If provided, the destination directory for saving merged files. Requires
|
|
the --output-item-list flag.
|
|
Can be provided alongside --output-target-files, or by itself.
|
|
|
|
--output-item-list output-item-list-file.
|
|
The optional path to a newline-separated config file that specifies the
|
|
file patterns to copy into the --output-dir. Required if providing
|
|
the --output-dir flag.
|
|
|
|
--output-ota output-ota-package
|
|
The output ota package. This is a zip archive. Use of this flag may
|
|
require passing the --path common flag; see common.py.
|
|
|
|
--output-img output-img-package
|
|
The output img package, suitable for use with 'fastboot update'. Use of
|
|
this flag may require passing the --path common flag; see common.py.
|
|
|
|
--output-super-empty output-super-empty-image
|
|
If provided, creates a super_empty.img file from the merged target
|
|
files package and saves it at this path.
|
|
|
|
--rebuild_recovery
|
|
Deprecated; does nothing.
|
|
|
|
--allow-duplicate-apkapex-keys
|
|
If provided, duplicate APK/APEX keys are ignored and the value from the
|
|
framework is used.
|
|
|
|
--rebuild-sepolicy
|
|
If provided, rebuilds odm.img or vendor.img to include merged sepolicy
|
|
files. If odm is present then odm is preferred.
|
|
|
|
--vendor-otatools otatools.zip
|
|
If provided, use this otatools.zip when recompiling the odm or vendor
|
|
image to include sepolicy.
|
|
|
|
--keep-tmp
|
|
Keep tempoary files for debugging purposes.
|
|
|
|
The following only apply when using the VSDK to perform dexopt on vendor apps:
|
|
|
|
--framework-dexpreopt-config
|
|
If provided, the location of framwework's dexpreopt_config.zip.
|
|
|
|
--framework-dexpreopt-tools
|
|
if provided, the location of framework's dexpreopt_tools.zip.
|
|
|
|
--vendor-dexpreopt-config
|
|
If provided, the location of vendor's dexpreopt_config.zip.
