Use String.getBytes().length to determine string length.

String.length() returns the number of UTF-16 code units,
but hidl_string objects are encoded in UTF-8; this will
cause verification failures in strings that are valid UTF-8,
but have a different number of code units in (Java's) UTF-16
encoding than in the native UTF-8 encoding.

Bug: 37722371
Bug: 63899698
Test: hidl_test_java with shiny UTF-8 string (that requires a
      different number of code units in UTF-16)

hidl-gen user guide

1. Build

croot
make hidl-gen

2. Run

hidl-gen -o output-path -L language (-r interface-root) fqname

output-path: directory to store the output files.
language: output file for given language. e.g.c++, vts..

fqname: fully qualified name of the input files.
For singe file input, follow the format: package@version::fileName
For directory input, follow the format: package@version

interface-root(optional): prefix and root path for fqname.
If not set, use the default prefix: android.hardware and default root path
defined in $TOP.

examples:

croot
hidl-gen -o output -L c++ -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0::INfc.hal
hidl-gen -o output -L vts -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
hidl-gen -o test -L c++ -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
hidl-gen -L hash -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
