android 获得自己的IP

低版本可以，2.3等，高版本不支持NetworkInterface

public String getLocalIpAddress() {

try {

for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {

NetworkInterface intf = en.nextElement();

for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {

InetAddress inetAddress = enumIpAddr.nextElement();

if (!inetAddress.isLoopbackAddress()) {

return i= inetAddress.getHostAddress().toString();

}

}

}

} catch (SocketException ex) {

Log.e(LOG_TAG, ex.toString());

}

return null;

}
