Start by locating DoKit's Android LeakCanary integration and the configuration or entry point used by version 3.2.0. Determine how a switch could control leak detection and whether its setting can take effect after the next restart. Done means the integration can be enabled or disabled, with restart-time activation accepted by the request.
