3fd0baf651 When a stub is built for APEX, it is generated with --apex
Now, symbols that are only to be visible to across APEXes can be tagged
as # vndk. Then when generating the stubs library, the tagged symbol
is included. The symbol is NOT included in other cases; build NDK stubs,
etc.

6437995170 Remove -include <file> when compiling stubs.
Otherwise, the force included headers might cause conflicting types
error with the symbols in the generated stubs source code. e.g.

double acos(double); // in header
void acos() {} // in the generated source code

0ddfcd1188 Don't create unnecessary APEX variations
This change fixes a problem that APEX variations are created for the
modules that actually shouldn't built for any APEX. For example,
consider this case.

apex { name: "myapex", native_shared_libs: ["mylib"],}

cc_library { name: "mylib", shared_libs: ["libfoo#10"],}
cc_library { name: "libfoo",
             shared_libs: ["libbar"],
             stubs: { versions: ["10"], }, }
cc_library { name: "libbar", ...}

Before this change, both the stubs and non-stubs variations of libfoo
were mutated with apexMuator, which is incorrect for the non-stubs
varia; there is no dependency chain from the apex "myapex" to the
non-stubs variation, but to the stubs variation due to the #10 syntax.

This was happening becauses we used the name of the module to determine
whether it should be built for APEX or not. Both stubs and non-stubs
variations have the same module name "libfoo".

Fixing this issue by recording the list of APEX variations required
directly on the module. So, the stubs variation of libfoo has myapex in
its apex variations list, but the non-stubs variation doesn't, and thus
apexMutator does not pick up the non-stubs variation.

28d395a149 Fix: build error when a lib with stubs is included in an APEX
apex { name: "foo", native_shared_libs: ["mylib"] }
cc_library { name: "mylib", shared_libs: ["other_lib"],
             stubs: { versions: ["1"]}, }

This is causing build error due to missing variant for other_lib.
This is happening because the stubs variant of mylib is added to apex
foo instead of the non-stubs variant. Because stubs variant does not
have any further dependencies, other_lib is not included to the APEX and
is not built for it.

Fixing this issue by specifying the version variant when adding a lib to
the dependency of an APEX, so that non-stub variant of the lib is
depended on.

7c2ee713ec Fix: a module with sub_dir can't be placed in APEX
This change fixes the bug that when a module is defined with sub_dir,
then build breaks when the module is included in an APEX.

This was happening because, for example when we have a prebuilt_etc
module having sub_dir set to "foo/bar", then only etc/foo/bar is added
to the canned_fs_config file and other intermediate directories (etc,
etc/foo) are not added. e2fsdroid however expects that every directories
to be listed.

Fixing the problem by adding parent directories when adding a directory
to canned_fs_config.

5098a612fc Add zip-apex
This adds support for an apex-like file where the payload is a zip
file instead of a FS image. This makes it easier to examine and use
without root. These can also be built for the host.

This can be controlled using the 'type' modifier in the apex build
rule. 'type' may be "image" to build an apex file called {name}.apex
with an FS image payload, "zip" to build an apex with called
{name}.zipapex with a zip-file payload or "both" to build both. By
default we will use "image".

This also adds support for setting apex rules to
"host_supported: true".

Test: cd art/build/apex; mma; examine the com.android.runtime.host.zipapex
      artifact.
Test: go test android/soong/apex -v

25fc6a9cc9 Stubs variant is used when building for APEX
When a native module is built for an APEX and is depending on a native
library having stubs (i.e. stubs.versions property is set), the stubs
variant is used unless the dependent lib is directly included in the
same APEX with the depending module.

Example:

apex {
    name: "myapex",
    native_shared_libs: ["libX", "libY"],
}

cc_library {
    name: "libX",
    shared_libs: ["libY", "libZ"],
}

cc_library {
    name: "libY",
    stubs: { versions: ["1", "2"], },
}

cc_library {
    name: "libZ",
    stubs: { versions: ["1", "2"], },
}

In this case, libX is linking to the impl variant of libY (that provides
private APIs) while libY is linking to the version 2 stubs of libZ. This is
because libY is directly included in the same apex via
native_shared_libs property, but libZ isn't.

8fd6192480 APEX can be flattened
When TARGET_FLATTEN_APEX is set to true, APEXes are flattened, which
means files in an APEX is not packaged into the mini file system image,
but instead directly copied to the system partition.

This option is for devices where kernel does not support loopback
devices or the maximum number of loopback devices is too small (though
the threshold is TBD as of now).

This CL also fixes a bug that jars having bytecode are installed instead
of those having dex.

For centralized development of sepolices, file_contexts files for APEXes

The meaning of the existing file_contexts has been changed; when it is
set to <value>, then /system/sepolicy/apex/<value>_file_contexts is
used. When unset, it defaults to the name of the module. The property is
not removed in order to support creating multiple versions of the same

2b11f74130 Fix ext4 image's root directory permissions of APEX packages.
The generateFsConfig rule used to not give execution

stored in an APEX package. This change add these bits, turning the
permissions from 0644 (drw-r--r--) to 0755 (drwxr-xr-x).

Previously, not having the execution permissions on the ext4 image's
root directory meant that the contents of the top-level directory of

397e55e0cf binaries and native_shared_libraires are multilib-aware props
The properties 'binaries' and 'native_shared_libraries' can be
multilib-aware, i.e, can be under multilib.type where type can be either
first, both, lib32, lib64, or prefer32.

Native modules listed in multilib.first are installed only for the first
ABI of the device. Similarily, multilib.both are for both of the ABIs,
while multilib.lib32 and multilib.lib64 are 32 and 64-bit ABI only,
respectively. multilib.prefer32 is for 32-bit only when 32-bit ABI is
available.

Another change is that the binaries property, when not within multilib,
targets only the first ABI.

Test: m apex.test on ...

2) aosp_arm64 with TARGET_PREFER_32_BIT_EXECUTABLES=true
3) aosp_arm
in all cases, vold, surfaceflinger and drmserver are all intalled under
./bin directory of the APEX. And native libraries are installed under
both ./lib and ./lib64 directories in the case of 1) and 2).

678529ef29 arch-specific dependencies are correctly handled in apex
The change fixes the problem that multiple APEXs having native component
(shared lib or executable) can't be built with an error similar to this:

error: bionic/linker/Android.bp:298:1: failed to find variation "com.android.art" for module "libclang_rt.builtins-aarch64-android" needed by "ld-android"

This is happening because the dependency to the built-in library is
arch-specific but apex.go ignores it. Specifically, let's assume that
32-bit variant of libFoo depends on libX while 64-bit variant of libFoo
depends on libY. Also assume that libFoo is included in two APEXs: apex1
(which is 64-bit) and apex2 (which is 32-bit). Then apexDepsMutator
records that libFoo shall be split into apex1 and apex2, while libX will
be only split into apex1 and libY will be split into apex2.

The problem is that, during apexMutator, both 32 and 64-bit varants of
libFoo are split into apex1 and apex2. As a result, a dependency to
apex2 variant of libX and a dependency to apex1 variant of libY are
requested, which don't exist.

Fixing this issue by using module's name AND target string as the key.
So, only the 32-bit variant of libFoo is split into apex1 and 64-bit
variant of libFoo is split into apex2.

Test: have following module somewhere. `m` is successful.

  apex {
      name: "com.android.art",
      manifest: "manifest.json",
      file_contexts: "file_contexts",

48ca7dc535 Add apex variants
Now, APEX-aware modules (the ones implementing android.ApexModule
interface) are created with multiple variants for each APEX that they
are included.

For example, if a module is included (either directly or indirectly -
via static linking) to two APEXs, the module is built separately for the
two APEXs (and of course separately for platform). This is a first step
to limit the symbol visibility to the modules built for APEXs; platform
private symbols and libs shouldn't be allowed for them.

In addition, the build system now tracks transitive dependencies of
the modules in APEXs. For example, if
native_shared_lib_modules:["libFoo"] then libFoo and its dependencies
are all automatically included to the APEX.

Bug: 112672359
