    Specified by:

    teardown in interface NetworkStateTracker

    Returns:

    true if a teardown occurred, false if the teardown did not occur.

    Re-enable connectivity to a network after a teardown().

    Specified by:

    reconnect in interface NetworkStateTracker

    Returns:

    true if we're connected or expect to be connected

  • captivePortalCheckComplete

    public void captivePortalCheckComplete()

    Description copied from interface: NetworkStateTracker
    Ready to switch on to the network after captive portal check

    Specified by:

    captivePortalCheckComplete in interface NetworkStateTracker

  • setRadio

    public boolean setRadio(boolean turnOn)

    Turn the wireless radio off for a network.

    Specified by:

    setRadio in interface NetworkStateTracker

    Parameters:

    turnOn - true to turn the radio on, false

  • isAvailable

    public boolean isAvailable()

    Description copied from interface: NetworkStateTracker
    Returns an indication of whether this network is available for connections. A value of false means that some quasi-permanent condition prevents connectivity to this network. NOTE that this is broken on multi-connection devices. Should be fixed in J release TODO - fix on multi-pdp devices

    Specified by:

    isAvailable in interface NetworkStateTracker

    Returns:

    true - If are we currently tethered with another device.

  • startUsingNetworkFeature

    public int startUsingNetworkFeature(String feature,
                               int callingPid,
                               int callingUid)

    Tells the underlying networking system that the caller wants to begin using the named feature. The interpretation of feature is completely up to each networking implementation.

    Parameters:

    feature - the name of the feature to be used

    callingPid - the process ID of the process that is issuing this request

    callingUid - the user ID of the process that is issuing this request

    Returns:

    an integer value representing the outcome of the request. The interpretation of this value is specific to each networking implementation+feature combination, except that the value -1 always indicates failure. TODO: needs to go away

    Tells the underlying networking system that the caller is finished using the named feature. The interpretation of feature is completely up to each networking implementation.

    Parameters:

    feature - the name of the feature that is no longer needed.

    callingPid - the process ID of the process that is issuing this request

    callingUid - the user ID of the process that is issuing this request

    Returns:

    an integer value representing the outcome of the request. The interpretation of this value is specific to each networking implementation+feature combination, except that the value -1 always indicates failure. TODO: needs to go away
