Usage: art [OPTIONS] [--] [ART_OPTIONS] CLASS

Supported OPTIONS include:
  --32                     Use the 32-bit Android Runtime.
  --64                     Use the 64-bit Android Runtime.
  -d                       Use the debug ART library (libartd.so).
  --debug                  Equivalent to -d.
  --gdb                    Launch the Android Runtime in gdb.
  --gdbserver <comms>      Launch the Android Runtime in gdbserver using the
                           supplied communication channel.
  --help                   Display usage message.
  --invoke-with <program>  Launch the Android Runtime in <program>.
  --perf                   Launch the Android Runtime with perf recording.
  --perf-report            Launch the Android Runtime with perf recording with
                           report upon completion.
  --profile                Run with profiling, then run using profile data.
  --verbose                Run script verbosely.
  --no-clean               Don't cleanup oat directories.
  --no-compile             Don't invoke dex2oat before running.
  --allow-default-jdwp     Don't automatically put in -XjdwpProvider:none.
                           You probably do not want this.

The ART_OPTIONS are passed directly to the Android Runtime.

Example:
  art --32 -cp my_classes.dex MainClass

Common errors:
  1) Not having core.art available (see $ANDROID_BUILD_TOP/art/Android.mk).
     eg m -j32 build-art-host
  2) Not having boot.art available (see $ANDROID_BUILD_TOP/build/make/core/dex_preopt_libart_boot.mk)
     eg m -j32 out/target/product/generic_x86_64/dex_bootjars/system/framework/x86_64/boot.art
