Remarks

Class that answers queries about the state of network connectivity. It also notifies applications when network connectivity changes.

The primary responsibilities of this class are to: <ol> <li>Monitor network connections (Wi-Fi, GPRS, UMTS, etc.)</li> <li>Send broadcast intents when network connectivity changes</li> <li>Attempt to "fail over" to another network when connectivity to a network is lost</li> <li>Provide an API that allows applications to query the coarse-grained or fine-grained state of the available networks</li> <li>Provide an API that allows applications to request and select networks for their data traffic</li> </ol>

Constructors

ConnectivityManager(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Fields

ActionBackgroundDataSettingChanged	Obsolete. Broadcast Action: The setting for background data usage has changed values.

ExtraIsFailover	The lookup key for a boolean that indicates whether a connect event is for a network to which the connectivity manager was failing over following a disconnect on another network.
ExtraNetwork	The lookup key for a `Network` object included with the intent after successfully finding a network for the applications request.
ExtraNetworkInfo	Obsolete. The lookup key for a `NetworkInfo` object.

ExtraOtherNetworkInfo	The lookup key for a `NetworkInfo` object.
ExtraReason	The lookup key for a string that indicates why an attempt to connect to a network failed.
RestrictBackgroundStatusDisabled	Obsolete. Device is not restricting metered network activity while application is running on background.
RestrictBackgroundStatusEnabled	Obsolete. Device is restricting metered network activity while application is running on background.
RestrictBackgroundStatusWhitelisted	Obsolete. Device is restricting metered network activity while application is running on background, but application is allowed to bypass it.
