FeatureFlagTargetPreparer

public class FeatureFlagTargetPreparer
extends BaseTargetPreparer

This class is deprecated.
Use AFlagsTargetPreparer instead.

Updates the DeviceConfig (feature flags tuned by a remote service).

This can be used to reproduce the state of a device (by dumping all flag values to a file using `adb shell device_config list`) or to bulk enable/disable flags (all-on/all-off testing).

Example usage:

• To use for all-on/all-off testing, specify the necessary flag file:

  --flag-file=flag_file_path

• To override one or more flags, specify their values (can be combined with flag files):

  --flag-file=flag_file_path --flag-value=namespace/name=value

• To use for reversibility testing, specify the all-on file followed by the all-off file, and enable rebooting between the two files:

  --flag-file=all_on_file_path --flag-file=all_off_file_path --reboot-between-flag-files
         

Should be used in combination with DeviceSetup to disable DeviceConfig syncing during the test which could overwrite the changes made by this preparer.
