This is a plug-in for Locale and Tasker that can be used to have the Scanner Radio app automatically perform various actions such as start playing one of your favorite scanner feeds, automatically stop playing a scanner, display your favorites, or display nearby scanners based on certain conditions occurring.
This plug-in will control only Scanner Radio. If you want to control Scanner Radio Pro, you need to install "Scanner Radio Pro Locale Plgin", also available for free in the Google Play Store.
In order to use this plug-in you *must* have Scanner Radio installed (in addition to Tasker or Locale).
Using this plug-in, you could have Locale or Tasker automatically have Scanner Radio start playing a scanner when a Bluetooth connection is established with your car and have it automatically stop playing when the connection is lost.
