Get current IP address of device

[t...@pixelsedge.ca]

I have the need to capture the users IP address and pass that along as part of a call. What I used was

import java.net.InetAddress;

text += ":" + InetAddress.getLocalHost().getHostAddress();

but that doesn't seem to be supported by the platform... Can someone suggest one that will work?

Thanks

This is supported as part of the Socket API in com.codename1.io:
Socket.getHostOrIP().

[t...@pixelsedge.ca]

Awesome! Thats exactly what I needed. Thanks :)

I have run com.codename1.io.Socket.getHostOrIP() on Galaxy 4 and getting  (localhost 127.0.0.1) back

I need the IP address assigned to my wifi connection like 192.168.1.123

Please advise.

Did you run this on the device?

[shop.servic...@gmail.com]

Yes, this ran on Samsung model sch-1545, android version 5.0.1

[Shai Almog]

OK, I see an issue. We'll fix it for the next update

[shop.servic...@gmail.com]

Thanks,

No Pressure, roughly can we expect this update?

Check out the git project. I already committed it yesterday. It should be up by Friday.

Thanks, Appreciate your looking at this.

I don't understand "It should be up by Friday"

How do these updates work?

Seamlessly.
When you send a build a new version will be used and you will receive updated libraries.

Thanks.

I have tested this today:

deviceIP.setText(com.codename1.io.Socket.getHostOrIP());

is returning "localhost"

Should be returningthe 192.168.1.114 IP address assigned to the wireless network.

Thoughts?

[Shai Almog]

I guess that means the fix failed in which case we'll need to re-examine it. Please file an issue in git.

Thanks.

 

Done.

com.codename1.io.Socket.getHostOrIP() on Android is now returning what appears to be an IPV6 address.

"fe80::ce3a:61ff:fe06:7346%wlan0"

Thoughts?

It looks like a valid operator hostname. Keep in mind that a device has more than one network interface (cell, wifi, roam...).

This is the code that implements this feature https://github.com/codenameone/CodenameOne/blob/master/Ports/Android/src/com/codename1/impl/android/AndroidImplementation.java#L7373-L7396

You can try and fix it. Then submit a pull request https://www.codenameone.com/blog/how-to-use-the-codename-one-sources.html

Or you can use a native interface to get the result you want: https://www.codenameone.com/how-do-i---access-native-device-functionality-invoke-native-interfaces.html

Thanks,

I would prefer to use all Codenameone generic interfaces/translations so I don't lock myself into a specific device/OS

Can we get the enumeration of all interfaces and decide which ones we want?

Curious, I don't even know what to do with this return string "fe80::ce3a:61ff:fe06:7346%wlan0".

Is there a way to translate this to an xxx.xxx.xxx.xxx net address?

Currently we don't have such an API. It gets pretty hairy even in native Java SE/Android as you can see from the API calls above.
It's worse since this can change dynamically as the user walks around...
