 /**
+ * This atom is deprecated starting in R.
+ *
  * Logs when an app causes Wifi to run. In this context, 'to run' means to use Wifi Client Mode.
  * TODO: Include support for Hotspot, perhaps by using an extra field to denote 'mode'.
  * Note that Wifi Scanning is monitored separately in WifiScanStateChanged.
