Install VNDK snapshot libraries for system build
When BOARD_VNDK_VERSION := <VNDK version>, or
PRODUCT_EXTRA_VNDK_VERSIONS includes the needed <VNDK version> list,
the prebuilt VNDK libs in prebuilts/vndk/ directory will be
installed.
Each prebuilt VNDK module uses "vndk_prebuilt_shared" for shared
VNDK/VNDK-SP libs.
Following is the sample configuration of a vndk snapshot module:
vndk_prebuilt_shared {
name: "libfoo",
version: "27",
vendor_available: true,
vndk: {
enabled: true,
},
arch: {
arm64: {
srcs: ["arm/lib64/libfoo.so"],
},
arm: {
srcs: ["arm/lib/libfoo.so"],
},
},
}
The Android.bp for the snapshot modules will be auto-generated by a
script.
