Shared libraries are now installed to different directories depending on
their types.
* NDK libraries: /system/lib/ndk
* VNDK libraries: /system/lib/vndk
* VNDK-ext libraries: /system/lib/vndk-ext
* Framework-only libraries: /system/lib
* Vendor-only libraries: /vendor/lib
* Same-process HALs: /vendor/lib/sameprocess
In addition, a new module type vndk_ext_library is added. It is almost
identical to cc_shared_library but it introduces another attribute
'extends'. This is use to reference the vndk library that this vndk-ext
library is extending.
For example, in order to extend a vndk library libFoo:
cc_library {
name: "libFoo",
srcs: [...]
}
---------------------
vndk_ext_library {
name: "libFoo-extended",
srcs: [...]
extends: "libFoo"
}
Then, libFoo will be installed as /system/lib/vndk/libFoo.so and
libFoo-extended will be installed as /system/lib/vndk-ext/libFoo.so.
Note that file name of the latter is libFoo.so, not libFoo-extended.so:
file name of an extending module is automatically set to that of the
extended module.
Bug: 33681361
Test: build & run. Libraries must be in the correct directories.
