name
string, The name of the module. Must be unique across all modules.
src
string, Source file of this prebuilt.
host_supported
bool, If set to true, build a variant of the module for the host. Defaults to false.
device_supported
bool, If set to true, build a variant of the module for the device. Defaults to true.
arch
interface
compile_multilib
string, control whether this module compiles for 32-bit, 64-bit, or both. Possible values
are "32" (compile for 32-bit only), "64" (compile for 64-bit only), "both" (compile for both
architectures), or "first" (compile for 64-bit on a 64-bit platform, and 32-bit on a 32-bit
platform
device_specific
bool, whether this module is specific to a device, not only for SoC, but also for off-chip
peripherals. When set to true, it is installed into /odm (or /vendor/odm if odm partition
does not exist, or /system/vendor/odm if both odm and vendor partitions do not exist).
This implies `soc_specific:true`.
⊕dist
targets
list of strings, copy the output of this module to the $DIST_DIR when `dist` is specified on the
command line and any of these targets are also on the command line, or otherwise
built
dest
string, The name of the output artifact. This defaults to the basename of the output of
the module.
dir
string, The directory within the dist directory to store the artifact. Defaults to the
top level directory ("").
suffix
string, A suffix to add to the artifact file name (before any extension).
enabled
bool, emit build rules for this module
Disabling a module should only be done for those modules that cannot be built
in the current environment. Modules that can build in the current environment
but are not usually required (e.g. superceded by a prebuilt) should not be
disabled as that will prevent them from being built by the checkbuild target
and so prevent early detection of changes that have broken those modules.
filename
string, optional name for the installed file. If unspecified, name of the module is used as the file name
filename_from_src
bool, when set to true, and filename property is not set, the name for the installed file
is the same as the file name of the source file.
host_required
list of strings, names of other modules to install on host if this module is installed
init_rc
list of strings, init.rc files to be installed if this module is installed
installable
bool, Whether this module is directly installable to one of the partitions. Default: true.
licenses
list of strings, Names of the licenses that apply to this module.
multilib
interface
native_bridge_supported
bool, Whether this module is built for non-native architecures (also known as native bridge binary)
notice
string, relative path to a file to include in the list of notices for the device
owner
string, vendor who owns this module
product_specific
bool, whether this module is specific to a software configuration of a product (e.g. country,
network operator, etc). When set to true, it is installed into /product (or
/system/product if product partition does not exist).
proprietary
bool, whether this is a proprietary vendor module, and should be installed into /vendor
ramdisk
bool, Whether this module is installed to ramdisk
recovery
bool, Whether this module is installed to recovery partition
required
list of strings, names of other modules to install if this module is installed
soc_specific
bool, whether this module is specific to an SoC (System-On-a-Chip). When set to true,
it is installed into /vendor (or /system/vendor if vendor partition does not exist).
sub_dir
string, optional subdirectory under which this file is installed into
symlinks
list of strings, install symlinks to the binary
system_ext_specific
bool, whether this module extends system. When set to true, it is installed into /system_ext
(or /system/system_ext if system_ext partition does not exist).
target
interface
⊕target.host, target.android
target_required
list of strings, names of other modules to install on target if this module is installed
vendor
bool, whether this module is specific to an SoC (System-On-a-Chip). When set to true,
it is installed into /vendor (or /system/vendor if vendor partition does not exist).
Use `soc_specific` instead for better meaning.
vintf_fragments
list of strings, VINTF manifest fragments to be installed if this module is installed
visibility
list of strings, Controls the visibility of this module to other modules. Allowable values are one or more of
these formats:
["//visibility:public"]: Anyone can use this module.
["//visibility:private"]: Only rules in the module's package (not its subpackages) can use
this module.
["//visibility:override"]: Discards any rules inherited from defaults or a creating module.
Can only be used at the beginning of a list of visibility rules.
["//some/package:__pkg__", "//other/package:__pkg__"]: Only modules in some/package and
other/package (defined in some/package/*.bp and other/package/*.bp) have access to
this module. Note that sub-packages do not have access to the rule; for example,
//some/package/foo:bar or //other/package/testing:bla wouldn't have access. __pkg__
is a special module and must be used verbatim. It represents all of the modules in the
package.
["//project:__subpackages__", "//other:__subpackages__"]: Only modules in packages project
or other or in one of their sub-packages have access to this module. For example,
//project:rule, //project/library:lib or //other/testing/internal:munge are allowed
to depend on this rule (but not //independent:evil)
["//project"]: This is shorthand for ["//project:__pkg__"]
[":__subpackages__"]: This is shorthand for ["//project:__subpackages__"] where
//project is the module's package. e.g. using [":__subpackages__"] in
packages/apps/Settings/Android.bp is equivalent to
//packages/apps/Settings:__subpackages__.
["//visibility:legacy_public"]: The default visibility, behaves as //visibility:public
for now. It is an error if it is used in a module.
If a module does not specify the `visibility` property then it uses the
`default_visibility` property of the `package` module in the module's package.
If the `default_visibility` property is not set for the module's package then
it will use the `default_visibility` of its closest ancestor package for which
a `default_visibility` property is specified.
If no `default_visibility` property can be found then the module uses the
global default of `//visibility:legacy_public`.
The `visibility` property has no effect on a defaults module although it does
apply to any non-defaults module that uses it. To set the visibility of a
defaults module, use the `defaults_visibility` property on the defaults module;
not to be confused with the `default_visibility` property on the package module.
See https://android.googlesource.com/platform/build/soong/+/master/README.md#visibility for
more details.

list of strings, install symlinks to the binary
system_ext_specific
bool, whether this module extends system. When set to true, it is installed into /system_ext
(or /system/system_ext if system_ext partition does not exist).
target
interface
⊕target.host, target.android
target_required
list of strings, names of other modules to install on target if this module is installed
test_config
string, the name of the test configuration (for example "AndroidTest.xml") that should be
installed with the module.
test_config_template
string, the name of the test configuration template (for example "AndroidTestTemplate.xml") that
should be installed with the module.
test_suites
list of strings, list of compatibility suites (for example "cts", "vts") that the module should be
installed into.
vendor
bool, whether this module is specific to an SoC (System-On-a-Chip). When set to true,
it is installed into /vendor (or /system/vendor if vendor partition does not exist).
Use `soc_specific` instead for better meaning.
vintf_fragments
list of strings, VINTF manifest fragments to be installed if this module is installed
visibility
list of strings, Controls the visibility of this module to other modules. Allowable values are one or more of
these formats:
["//visibility:public"]: Anyone can use this module.
["//visibility:private"]: Only rules in the module's package (not its subpackages) can use
this module.
["//visibility:override"]: Discards any rules inherited from defaults or a creating module.
Can only be used at the beginning of a list of visibility rules.
["//some/package:__pkg__", "//other/package:__pkg__"]: Only modules in some/package and
other/package (defined in some/package/*.bp and other/package/*.bp) have access to
this module. Note that sub-packages do not have access to the rule; for example,
//some/package/foo:bar or //other/package/testing:bla wouldn't have access. __pkg__
is a special module and must be used verbatim. It represents all of the modules in the
package.
["//project:__subpackages__", "//other:__subpackages__"]: Only modules in packages project
or other or in one of their sub-packages have access to this module. For example,
//project:rule, //project/library:lib or //other/testing/internal:munge are allowed
to depend on this rule (but not //independent:evil)
["//project"]: This is shorthand for ["//project:__pkg__"]
[":__subpackages__"]: This is shorthand for ["//project:__subpackages__"] where
//project is the module's package. e.g. using [":__subpackages__"] in
packages/apps/Settings/Android.bp is equivalent to
//packages/apps/Settings:__subpackages__.
["//visibility:legacy_public"]: The default visibility, behaves as //visibility:public
for now. It is an error if it is used in a module.
If a module does not specify the `visibility` property then it uses the
`default_visibility` property of the `package` module in the module's package.
If the `default_visibility` property is not set for the module's package then
it will use the `default_visibility` of its closest ancestor package for which
a `default_visibility` property is specified.
If no `default_visibility` property can be found then the module uses the
global default of `//visibility:legacy_public`.
The `visibility` property has no effect on a defaults module although it does
apply to any non-defaults module that uses it. To set the visibility of a
defaults module, use the `defaults_visibility` property on the defaults module;
not to be confused with the `default_visibility` property on the package module.

more details.
