Localized apps, LANG environment variables, and .po files

[GJTorikian]

It is not clear to me how to reference/set the LANG environment
variable in a pure C app in order to provide a localized experience.

I have gettext() calls throughout my code, and I have a .po folder
with some definitions. It seems that the only piece I am unable to
figure out is setting LANG. I can make a call in Java to get the
language settings a user has for his or her device. Can I assume a
language is set already and that the proper .po file will be selected
for localization?

Locales are not supported on Android, or to be more precise, anything other than the "C" locale is not supported from native code.

You will thus need to call the VM to get the current locale. According to http://developer.android.com/guide/topics/resources/localization.html this looks like doing the equivalent of:

String locale = context.getResources().getConfiguration().locale.getDisplayName();

through JNI.

Hope this helps

Thanks very much. I'll try to pass in the locale to the JNI. Cheers!
