Example 1 with InterfaceConfiguration

use of android.net.InterfaceConfiguration in project android_frameworks_base by ParanoidAndroid.

the class CommonTimeManagementService method reevaluateServiceState.

    String bindIface = null;

    try {
        // Check to see if this interface is suitable to use for time synchronization.
        //
        // TODO : This selection algorithm needs to be enhanced for use with mobile devices.  In
        // particular, the choice of whether to a wireless interface or not should not be an all
        // or nothing thing controlled by properties.  It would probably be better if the
        // platform had some concept of public wireless networks vs. home or friendly wireless
        // networks (something a user would configure in settings or when a new interface is
        // added).  Then this algorithm could pick only wireless interfaces which were flagged
        // as friendly, and be dormant when on public wireless networks.
        //
        // Another issue which needs to be dealt with is the use of driver supplied interface
        // name to determine the network type.  The fact that the wireless interface on a device
        // is named "wlan0" is just a matter of convention; its not a 100% rule.  For example,
        // there are devices out there where the wireless is name "tiwlan0", not "wlan0".  The
        // internal network management interfaces in Android have all of the information needed
        // to make a proper classification, there is just no way (currently) to fetch an
        // interface's type (available from the ConnectionManager) as well as its address
        // (available from either the java.net interfaces or from the NetworkManagment service).
        // Both can enumerate interfaces, but that is no way to correlate their results (no
        // common shared key; although using the interface name in the connection manager would
        // be a good start).  Until this gets resolved, we resort to substring searching for
        // tags like wlan and eth.
