name string, The name of the module. Must be unique across all modules.

 src string, Source file of this prebuilt.

 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`.

 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 Modules that can build in the current environment but are not usually required (e.g. superceded by a prebuilt) should not be disabled as that will prevent them from being built by the checkbuild target and so prevent early detection of changes that have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

 ramdisk_available bool, Make this module available when building for ramdisk.

 recovery bool, Whether this module is installed to recovery partition

 recovery_available bool, Make this module available when building for recovery.

 required list of strings, names of other modules to install if this module is installed

 schema string, Optional DTD that will be used to validate the xml file.

 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

 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_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.
