Android and iOS Application's language does not match

[lano-vargas]

I have implemented the localize plugin, and Im' facing issues:

"get the default language on user's phone via the language property of the Device class."

I have Android which phone language setting is set United Kingdom (en) this picks up correctly. On iOS I also have the setting language to English as preferred language but this isn't printing correctly. I the following code.

    console.log('DEVICE LANGUAGE', device.language);
    console.log('From Cores, Device.language);
    console.log('from __app__language__', ApplicationSettings.getString('__app__language__'))
    const localeOverriddenSuccessfully = overrideLocale(Device.language); 

On Android is correct:

On iOS is incorrect:

ns --version 8.5.3 ✔ Up to date.

============================================= It seems to me that on iOS some how it cached into the the phone's default language variables, earlier on I was manually updating the language like so: const localeOverriddenSuccessfully = overrideLocale('nl'); could this have been cached for iOS on this variables prior?

device.language Device.language __app__language__

Depending on your code, if you followed the README, you may have added:

Application.on(Application.launchEvent, (args) => {
	if (args.android) {
		androidLaunchEventLocalizationHandler();
	}
});

that resets the language (i.e. remove __app__language setting).

This doesn't exist for iOS so __app__language still exist and therefore is still used to localise your app.

earlier on I was manually updating the language like so

I guess you removed the overrideLocale('nl') so iOS is still using __app__language and android's one has been reset.

Re-installing the app will remove the app settings and use the correct language. If you want to "reproduce" the same behaviour as android, I would simply add:

Application.on(Application.launchEvent, (args) => {
	if (args.android) {
		androidLaunchEventLocalizationHandler();
	}
       if (args.ios) {
		ApplicationSettings.remove('__app__language__');
	}
});

On a personal note, I have never used this androidLaunchEventLocalizationHandler() function and it seems to work :)
