Please check this link What is the list of supported languages/locales on Android? for supported language.
&
you can do this by simply changing the Locale of your application like this in your Splash or where you loading the maps.
String languageToLoad = "ar";
Locale locale = new Locale(languageToLoad);
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
getBaseContext().getResources().getDisplayMetrics());
Hope this may help you.

Ignore phone's locale and always use English as locale

Is there a way to force using english as the locale for my android app even if the phone's locale is something other that english? The reason I want to do this is that I don't want my UI to change orientatoin from ltr to rtl.

this line
mStrLocale = Locale.getDefault().getLanguage();
will return your current language, lets say EN-US
and with this you can hardcode your locale
Locale locale = new Locale("ru");
Locale.setDefault(locale);
Configuration config = getBaseContext().getResources().getConfiguration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
getBaseContext().getResources().getDisplayMetrics());
and we use Configuration because of this
This class describes all device configuration information that can
impact the resources the application retrieves. This includes both
user-specified configuration options (locale list and scaling) as well
as device configurations (such as input modes, screen size and screen
orientation).
is stated at this doc https://developer.android.com/reference/android/content/res/Configuration.html

Android: Change number format for the whole application?

In Android we can change the applications locale like this:
Locale locale = new Locale("ar","EG");
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
context.getResources().updateConfiguration(config,
context.getResources().getDisplayMetrics());
and we can format the number to display digits according to a certaub locale like this:
NumberFormat nf=NumberFormat.getInstance(new Locale("ar","EG"));
nf.format(numberString);
I'm wondering if there is a way to just change the locale for the number format for the whole application without changing the application's locale? in other words is there a way to set the application's locale to "en-US" while set the number format only to "ar-EG"? is that possible?

Runtime display image from french drawable if language changed to french

I am developing an app with english and french language support.
If user change language , textview texts are changed.
But images in ImageView does not change.
If user selects language=='fr' image should be displayed from drawable-fr.
How to achieve this?
I am changing locale like:
Locale myLocale = new Locale(language);
// set the new locale
Locale.setDefault(myLocale);
Configuration config = new Configuration();
config.locale = myLocale;
getApplicationContext().getResources().updateConfiguration(config,
getApplicationContext().getResources().getDisplayMetrics());

I solved problem.
As user changes language,i was resetting image like iv.setImageResouse(R.drawable.asdf); in onRestart() method of previous activity.
But then i replaced this with iv.setImageDrawable(getResources().getDrawable(R.drawable.asdf));
This worked.
