  # - If Pre-reboot Dexopt is disabled or unsupported, the command returns

  #   non-zero. This is always the case if the current system is Android 14 or

  #   earlier.

  # - If Pre-reboot Dexopt is enabled in synchronous mode, the command blocks

  #   until Pre-reboot Dexopt finishes, and returns zero no matter it succeeds or

  #   not. This is the default behavior if the current system is Android 15.

  # - If Pre-reboot Dexopt is enabled in asynchronous mode, the command schedules

  #   an asynchronous job and returns 0 immediately. The job will then run by the

  #   job scheduler when the device is idle and charging.
