Name of activity to use for wallpaper on the home screen.

Whether to notify the user of open networks.

If not connected and the scan results have an open network, we will put this notification up. If we attempt to connect to a network or the open network(s) disappear, we remove the notification. When we show the notification, we will not show it again for WIFI_NETWORKS_AVAILABLE_REPEAT_DELAY time.

Delay (in seconds) before repeating the Wi-Fi networks available notification. Connecting to a network will reset the timer.

The timeout for a background ping

The number of initial pings to perform that *may* be ignored if they fail. Again, if these fail, they will *not* be used in packet loss calculation. For example, one network always seemed to time out for the first couple pings, so this is set to 3 by default.

The maximum number of access points (per network) to attempt to test. If this number is reached, the watchdog will no longer monitor the initial connection state for the network. This is a safeguard for networks containing multiple APs whose DNS does not respond to pings.

Convenience function to read all of the current configuration-related settings into a Configuration object.

Convenience function for retrieving a single system settings value as a floating point number. Note that internally setting values are always stored as strings; this function converts the string to an float for you. The default value will be returned if the setting is not defined or not a valid float.

This version does not take a default value. If the setting has not been set, or the string value is not a number, it throws Settings.SettingNotFoundException.

Construct the content URI for a particular name/value pair, useful for monitoring changes with a ContentObserver.

Convenience function to write a batch of configuration-related settings from a Configuration object.

Convenience function for updating a single settings value as a floating point number. This will either create a new entry in the table if the given name does not exist, or modify the value of the existing row with that name. Note that internally setting values are always stored as strings, so this function converts the given value to a string before storing it.
