Public methods

onNetworkActive

Added in API level 21

public abstract void onNetworkActive ()

Called on the main thread of the process to report that the current data network has become active, and it is now a good time to perform any pending network operations. Note that this listener only tells you when the network becomes active; if at any other time you want to know whether it is active (and thus okay to initiate network traffic), you can retrieve its instantaneous state with ConnectivityManager.isDefaultNetworkActive.
