Android N - Change Locale In Runtime

I have an android app to which I want to add a simple preferences screen with a single option to switch between to languages (english and portuguese). I have already the proper str

Solution 1:

Language @parameter that you are setting for Locale object should be

An ISO 639 alpha-2 or alpha-3 language code, or a language subtag
     * up to8 characters in length.

According to the documentation. Therefore if you're using something else, you'll not see the updating locales.
