This condition plugin for Locale and Tasker detects what type of internet connection is active on your device. Connection types that can be detected are wifi, Bluetooth PAN, mobile data, mobile roaming, or no connection.

This plugin is useful to sync files when you're on wifi, disable non-essential data usage when you're on a mobile data network, or warn yourself when you're connected to data roaming.

Important: This is only a plug-in. It requires either "Locale" or "Tasker" from the Google Play store.
