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

Example 6 with NetworkRequest

use of android.net.NetworkRequest in project platform_frameworks_base by android.

the class ConnectivityService method listenForNetwork.

@Override
public NetworkRequest listenForNetwork(NetworkCapabilities networkCapabilities, Messenger messenger, IBinder binder) {
    if (!hasWifiNetworkListenPermission(networkCapabilities)) {
        enforceAccessPermission();
    }
    NetworkCapabilities nc = new NetworkCapabilities(networkCapabilities);
    if (!ConnectivityManager.checkChangePermission(mContext)) {
        // Apps without the CHANGE_NETWORK_STATE permission can't use background networks, so
        // make all their listens include NET_CAPABILITY_FOREGROUND. That way, they will get
        // onLost and onAvailable callbacks when networks move in and out of the background.
        // There is no need to do this for requests because an app without CHANGE_NETWORK_STATE
        // can't request networks.
        nc.addCapability(NET_CAPABILITY_FOREGROUND);
    }
    NetworkRequest networkRequest = new NetworkRequest(nc, TYPE_NONE, nextNetworkRequestId(), NetworkRequest.Type.LISTEN);
    NetworkRequestInfo nri = new NetworkRequestInfo(messenger, networkRequest, binder);
    if (VDBG)
        log("listenForNetwork for " + nri);
    mHandler.sendMessage(mHandler.obtainMessage(EVENT_REGISTER_NETWORK_LISTENER, nri));
    return networkRequest;
}

Example 8 with NetworkRequest

use of android.net.NetworkRequest in project platform_frameworks_base by android.

the class ConnectivityService method processListenRequests.

Example 10 with NetworkRequest

use of android.net.NetworkRequest in project platform_frameworks_base by android.

    // Therefore, to avoid duplicate notifications, we only register a no-op.
    mMobileNetworkCallback = new UpstreamNetworkCallback(CALLBACK_MOBILE_REQUEST);
    // TODO: Change the timeout from 0 (no onUnavailable callback) to some
    // moderate callback timeout. This might be useful for updating some UI.
    // Additionally, we log a message to aid in any subsequent debugging.
