android Locale.Builder() doesn't mirror the page in right-to-left locales

Question

When I use

locale = new Locale("ar");

the screen is mirrored in the right way.

In order to give the option to set the numeric system, i have to use the Locale.Builder() inserted with lollipop.

locale = new Locale.Builder().setLanguage("ar").setRegion("MA").setExtension(Locale.UNICODE_LOCALE_EXTENSION, "nu-latn").build();

The problem is that in this way the screen is not mirrored properly. There is a way, like an Extension, to set the rtl attribute?

My impression is that the problem is with android ignoring RTL when you set the extension and not with Locale.Builder not doing its job. But I didn't find a way to fix it — kingston, Dec 14 '15 at 14:29

SOLUTION: In order to mirror the screen properly, you have to use the Configuration.

Configuration config = new Configuration();
config.locale = locale;
config.setLayoutDirection(new Locale("ar"));

with this config you create a new Resources and then you use these resources for getting the strings? – kingston Dec 15 '15 at 13:43
How do you force the context to use this new config? context.getApplicationContext().getResources().updateConfiguration(config, context.getApplicationContext().getResources().getDisplayMetrics()); – kingston Dec 15 '15 at 13:49
Another problem with the solution above is that after setting the extension the country is ignored so if you have en_gb and en_ie, en_gb is used for Ireland too – kingston Jan 04 '16 at 10:34
