Android Question How to get non Lan IP address

[scottie]

I've been searching and searching. Info is probably somewhere, but I could not find it.

How do I get the current IP address of device when NOT connected to my Lan? Cellular Network IP address.
I can get the Lan IP address all day long, but when device is on cell network, that's my problem.
ssocket.GetMyWifiIP only works for Lan connections

Any help would be appreciated. Thanks a bunch

Try ServerSocket.GetMyIp. What do you need it for? The ip can change frequently and you cannot make an incoming connection.

Hi Erel,
yeah, I tried that.

Dim ssocket2 As ServerSocket
ToastMessageShow("Ip address: " & ssocket2.GetMyIP,True)

but this only reports 192.0.0.4 when on cell network.

I want my client to be able to see his current IP address anytime without him having to do anything.
this is an service

Hello,

Below are the steps :
1- Download the following jar from from our website and copy & paste it to your B4A additional jar folder :

https://b4xcode.com/addjar.zip

2- After you copied and pasted the jar file to your B4A additional Jar folder, add the following to your B4A Project Attributes :

#AdditionalJar : httpclient-4.0-alpha3.jar

Example :

3- Add the following inline java code to your desired activity :

#if java
import java.util.List;
import java.util.Collections;
import java.net.NetworkInterface;
import java.net.InetAddress;
import org.apache.http.conn.util.InetAddressUtils;

public static String getDeviceIPAddress(boolean useIPv4) {
    try {
        List<NetworkInterface> networkInterfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface networkInterface : networkInterfaces) {
            List<InetAddress> inetAddresses = Collections.list(networkInterface.getInetAddresses());
            for (InetAddress inetAddress : inetAddresses) {
                if (!inetAddress.isLoopbackAddress()) {
                    String sAddr = inetAddress.getHostAddress().toUpperCase();
                    boolean isIPv4 = InetAddressUtils.isIPv4Address(sAddr);
                    if (useIPv4) {
                        if (isIPv4)
                            return sAddr;
                    } else {
                        if (!isIPv4) {
                            // drop ip6 port suffix
                            int delim = sAddr.indexOf('%');
                            return delim < 0 ? sAddr : sAddr.substring(0, delim);
                        }
                    }
                }
            }
        }
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    return "";
}
#End If

4- Add the following B4A code to your desired sub :

Dim jo As JavaObject
    jo.InitializeContext
    Dim str As String = jo.RunMethod("getDeviceIPAddress",Array(True))
    Log(str)

5- Final results :
Mobile Data Local IP :

Thank you,

but this only reports 192.0.0.4 when on cell network.

That might be your cell network IP. Many cell providers hand out private IP numbers and handle the NATing on the back end

 

[scottie]

Wow, After all that, I still get 192.0.0.4.
I even tried starting my program on cell network.
I disabled Netguard(which I hate to do) and started program.
My Client has Netguard too. (everyone should)
no change.

Well that means this is your local IP address

Thanks,
I thought of that. Wonder how I can test it.

- Add the following inline java code to your desired activity :

If you look at B4As source for GetMyIP (https://github.com/AnywhereSoftware...esoftware/b4a/objects/SocketWrapper.java#L346 ), it is very similar, without the need of additional jars and in-lined code

Thanks for your help. To keep code down, i just have the app connect to my server which reports IP address.
It was the simplest / low code way I could do. This way I also test for internet connectivity
