Change method name. We don't pass a count anymore. Bug: 176240491 Test: atest hidl_lazy_test Change-Id: I9600f6d017af281d4183a42802dbf914b1a7ef57
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.
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 parition by putting a marker file.hidl_for_system_ext
alongside*.hal
files.
This is a helper tool to convert C headers to valid .hal files.
