Add min_sdk_version(30) when generating cc modules

Those listed hidl_interface modules are used by mainline
modules(APEX/APK) and they should declare min_sdk_version accordingly.

Setting this prop doesn't change any build outputs, but will let the
module authors know that they contribute the mainlines modules which
target and should run on declared sdk version.

hidl-gen

Full documentation can be found here: https://source.android.com/devices/architecture/hidl/

hidl-gen is a compiler for the HIDL (HAL Interface Design Language) which generates C++ and Java endpoints for RPC mechanisms. The main userspace libraries which this compiler uses can be found at system/libhidl.

1. Build

m hidl-gen

2. Run

Note that options for hidl-gen expected to be invoked by the build system are marked with ‘internal’ in the help menu.

hidl-gen -h

hidl-gen -o output -L c++-impl -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport [email protected]

Some defaults for package roots are also provided

hidl-gen -o output -L c++-impl [email protected]
hidl-gen -o output -L vts [email protected]
hidl-gen -L hash [email protected]

Example command for vendor project

hidl-gen -L c++-impl -r vendor.foo:vendor/foo/interfaces [email protected]

See update-makefiles-helper.sh and update-all-google-makefiles.sh for examples of how to generate HIDL makefiles (using the -Landroidbp option).

c2hal

This is a helper tool to convert C headers to valid .hal files.

m c2hal && c2hal -h
