hidl_interface: generate VTS things Bug: 117348839 Test: refreshmod; m $(allmod | grep -P "vts\.(profiler|driver)") Test: m vts_specs # and check to see HALs are there Change-Id: I70a9a8bd7719d9d27041967f34614d057fc6f89c Merged-In: I70a9a8bd7719d9d27041967f34614d057fc6f89c

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).
This is a helper tool to convert C headers to valid .hal files.
m c2hal && c2hal -h
This tool generates html documentation for hal interfaces.
m hidl-doc && hidl-doc -h
