Android Question running cmd using shellasync

[mohammad javad]

I'm trying to get my real Public IP even if I use Proxy. After some research I found this command:

nslookup myip.opendns.com resolver1.opendns.com

This is run perfectly on cmd. I mean even if I use proxy it returns my real public IP. I tried to use shellasync to run it on B4A by below code but that is not running perfectly.

Sub myip
    Dim p As Phone
    Wait For (p.ShellAsync("nslookup", Array As String("myip.opendns.com","resolver1.opendns.com"))) Complete (Success As Boolean, ExitValue As Int, StdOut As String, StdErr As String)
    If Success Then
        Log(ExitValue)
        Log(StdErr)
        Log(StdOut)
    End If
End Sub

I have faced these logs

1
nslookup: can't resolve 'myip.opendns.com'
Server: 208.67.222.222
Address 1: 208.67.222.222


why can't it resolve?

What does it mean? Have you ran it from the device command line?

Phone.ShellAsync runs the command and returns the result. The error that you see comes from nslookup.

Have you ran it from the device command line?

Yes, I’m using Android emulator (bluestack) on my desktop. When I ran the code in desktop command prompt it is ok but when I use emulator to run Phone.shellasync I got that message.
Pay attention it works without error on logs or any other crash but it doesn’t return the answer which is returned by command prompt

There is no relation between the desktop command line and the emulator.
