Examples with Network android.net.Network used on opensource projects

Example 26 with Network

use of android.net.Network in project android_frameworks_base by AOSPA.

the class ConnectivityService method getDefaultNetworkCapabilitiesForUser.

@Override
public NetworkCapabilities[] getDefaultNetworkCapabilitiesForUser(int userId) {
    // The basic principle is: if an app's traffic could possibly go over a
    // network, without the app doing anything multinetwork-specific,
    // (hence, by "default"), then include that network's capabilities in
    // the array.
    //
    // In the normal case, app traffic only goes over the system's default
    // network connection, so that's the only network returned.
    //
    // With a VPN in force, some app traffic may go into the VPN, and thus
    // over whatever underlying networks the VPN specifies, while other app
    // traffic may go over the system default network (e.g.: a split-tunnel
    // VPN, or an app disallowed by the VPN), so the set of networks
    // returned includes the VPN's underlying networks and the system
    // default.
    enforceAccessPermission();

    NetworkAgentInfo nai = getDefaultNetwork();
