Hello everyone, Is there a way to detect the language of the operating system in B4J?
 
Solution
You can try this:

B4X: 
Public Sub getSystemLanguage As String
    ' Get the default locale of the system
    Dim defaultLocale As JavaObject
    defaultLocale.InitializeStatic("java.util.Locale")
    Dim systemLocale As JavaObject = defaultLocale.RunMethod("getDefault", Null)
   
    ' Get the language code of the default locale
    Return systemLocale.RunMethod("getLanguage", Null)
End Sub

This code works perfectly, in my case it returns the variable with the value "es". I want to see if GetSystemProperty("lang", "not found"), or whatever, performs better.

I found on Google, to show all the variables, in the command prompt you need to run:

java -XshowSettings:all

User = GetSystemProperty("user.language", ""), but is user not operating system.

If you want the language DisplayName change

B4X: 
Return systemLocale.RunMethod("getLanguage", Null)

to

B4X: 
Return systemLocale.RunMethod("getDisplayName", Null)

First one gives me 'en'
Second 'English (United Kingdom)'

Thanks @Daestrum, I need to identify the language with an id, getLanguage is the one I need.
My project is to make a B4X Ping, I have the B4A ready, the B4I halfway since I use @Erel's iPing and I don't know if it works in a class.

[SOLVED] iPing not working

I am trying to implement iPing from this post from @Erel . https://www.b4x.com/android/forum/threads/iping-send-and-receive-ping-icmp-packets.132440/ I don't know if a special permission is needed or what the problem is. If I solve this issue, I will have the B4X Ping ready. I am attaching the...

In the case of B4J, I did not find a native ping, just like B4A I am going to execute the CMD command with the Shell and capture the result. B4J becomes more complex because I depend on the language in which the operating system is installed.
Google Example for English: 
ping paessler.com

    (0% perdidos),
Tiempos aproximados de ida y vuelta en milisegundos:
    Mínimo = 14ms, Máximo = 16ms, Media = 15ms

To solve this issue, I am making a json file with the different character strings for the RegEx, depending on the language. I will make a post later asking forum users to copy and paste the text in other languages to cover all possible languages.



Thank you for your collaboration
