示例1: sendTunFD

private boolean sendTunFD(String needed, String extra) {
if (!extra.equals("tun")) {
// We only support tun
VpnStatus.logError(String.format("Device type %s requested, but only tun is possible with the Android API, sorry!", extra));
return false;
}
ParcelFileDescriptor pfd = mOpenVPNService.openTun();
if (pfd == null) return false;
Method setInt;
int fdint = pfd.getFd();
try {
setInt = FileDescriptor.class.getDeclaredMethod("setInt$", int.class);

mSocket.setFileDescriptorsForSend(fds);
// Trigger a send so we can close the fd on our side of the channel
// The API documentation fails to mention that it will not reset the file descriptor to
// be send and will happily send the file descriptor on every write ...
