Sandbox hidl genrules go/roboleaf-busy-beavers-sandboxing Most of these genrules work out of the box with sandboxing, I'm not sure why they were added. However hidl_hash_test_gen needs a fix, and hidl2aidl_translate_cpp_test_gen_src produces nondeterministic results even without sandboxing.

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.
m hidl-gen
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 android.hardware.nfc@1.0
Some defaults for package roots are also provided
hidl-gen -o output -L c++-impl android.hardware.nfc@1.0 hidl-gen -o output -L vts android.hardware.nfc@1.0 hidl-gen -L hash android.hardware.nfc@1.0
Example command for vendor project
hidl-gen -L c++-impl -r vendor.foo:vendor/foo/interfaces vendor.foo.nfc@1.0
See update-makefiles-helper.sh and update-all-google-makefiles.sh for examples of how to generate HIDL makefiles (using the -Landroidbp option).
NOTE: When using the -Landroidbp option, you can force generated modules to be installed in
/system_ext
rather than other partition by putting a marker file.hidl_for_system_ext
alongside*.hal
files.
NOTE: You can also install the vendor variant of the generated modules to be installed in
/odm
rather than/vendor
by putting a marker file.hidl_for_odm
alongside*.hal
files.
This is a helper tool to convert C headers to valid .hal files.
