ios & android: detect current language [SOLVED]

[Jibus]

Is there a way to detect the current language on mobile device ?

My aim is to adapt the language of the visual novel according to the language of the device

I don't know of any. If you can find an android or iOS API that can do this, it's something I can add to Ren'Py.

[Jibus]

In Python, I suppose ?

[Jibus]

ios :

NSString * language = [[NSLocale preferredLanguages] objectAtIndex:0];
Can we mimic this with Pyobjus ?

android :

Locale.getDefault().getDisplayLanguage()

[Jibus]

I am trying to detect the current local with Pyobjus, but i am bit stuck.

Code: Select all

init python:
    if renpy.ios:
        import pyobjus
        NSLocale = pyobjus.autoclass("NSLocale")
        languages = NSLocale.preferredLanguages()
        current_language = languages[0]

preferredLanguages should return the user's language preference order as an array of strings.

But current_language seems to be empty

[PyTom]

Have you tried languages.objectAtIndex_(0) ?

[Jibus]

Code: Select all

    if renpy.ios:
        import pyobjus
        NSLocale = pyobjus.autoclass("NSLocale")
        languages = NSLocale.preferredLanguages()
        current_language = str(languages.objectAtIndex_(0))

I got :

Code: Select all

___main___-____NSCFString object at 0x121ac4f50

[PyTom]

Maybe,

current_language = languages.objectAtIndex_(0).UTF8String().decode("utf-8")

will turn it into a unicode string properly.

[Jibus]

Yes ! It's working ! Thanks you PyTom

Here is the full code to get the current language in ios

Code: Select all

    if renpy.ios:
        import pyobjus
        NSLocale = pyobjus.autoclass("NSLocale")
        languages = NSLocale.preferredLanguages()
        current_language = languages.objectAtIndex_(0).UTF8String().decode("utf-8")

I will now look for android and post the result in this thread

[Jibus]

And here is the working code for android device :

Code: Select all

    if renpy.android:
        from jnius import autoclass
        Locale = autoclass('java.util.Locale')
        current_language = str(Locale.getDefault().getLanguage())

[PyTom]

Can I include this code in a future version of Ren'Py?

[Jibus]

No need to ask Of course !

[Jibus]

Bump this thread. I notice that the code for ios doesn't work anymore in the latest release.

I was wondering if you have change something that may have impacted this ?

Thanks in advance !

[PyTom]

What's broken about it?

[Jibus]

Found it!

It seems that iOS returns now the language and the region, ie: en-US.

Updated code:

Code: Select all

init python:
    if renpy.ios:
        import pyobjus
        NSLocale = pyobjus.autoclass("NSLocale")
        languages = NSLocale.preferredLanguages()
        current_language_region = languages.objectAtIndex_(0).UTF8String().decode("utf-8")
        current_language = current_language_region.split("-")

current_language[0] contains the language code and current_language[1] the region code.
