# Generate Android.bp for AOSP blob self-extractors.
|
|
#
|
|
# For example, a blob package may contain:
|
|
# ./vendor
|
|
# └── qcom
|
|
# └── coral
|
|
# └── proprietary
|
|
# ├── lib64
|
|
# | ├── libfoo.so
|
|
# | └── libbar.so
|
|
# ├── libfoo.so
|
|
# └── libbar.so
|
|
#
|
|
# Generate prebuilt modules for these blobs:
|
|
# $ export SYSTEM_EXT_SPECIFIC=true # If installing prebuilts to system_ext/ partition
|
|
# $ export OWNER=qcom # Owner is relevant if PRODUCT_RESTRICT_VENDOR_FILES is set
|
|
# $ ./generate-android-bp-for-blobs.sh ./vendor/qcom/coral/proprietary > Android.bp.txt
|
|
# $ mv Android.bp.txt ${ANDROID_BUILD_TOP}/device/google/coral/self-extractors/qcom/staging/
|
|
#
|
|
# You may need to review the contents of Android.bp.txt as some of the blobs may
|
|
# have unsatisfied dependencies. Add `check_elf_files: false` to bypass this
|
|
# kind of build errors.
