get the application's resources languages

Question

Is it possible, at runtime, to know which resources languages are embedded in my app?

i.e the presence of this folders:

values-en values-de values-fr ... 

Answer 1

It's complicated because even if you have a folder named values-de it doesn't mean you have any resources there. If you have string.xml in values-de it doesn't mean you have string value there.

values:

<resources>     <string name="app_name">LocTest</string>     <string name="hello_world">Hello world!</string>     <string name="menu_settings">Settings</string> </resources> 

values-de:

<resources>     <string name="hello_world">Hallo Welt!</string> </resources> 

You can test if a resource for a specific locale is different than the default:

DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); Resources r = getResources(); Configuration c = r.getConfiguration(); String[] loc = r.getAssets().getLocales(); for (int i = 0; i < loc.length; i++) {     Log.d("LOCALE", i + ": " + loc[i]);      c.locale = new Locale(loc[i]);     Resources res = new Resources(getAssets(), metrics, c);     String s1 = res.getString(R.string.hello_world);     c.locale = new Locale("");     Resources res2 = new Resources(getAssets(), metrics, c);     String s2 = res2.getString(R.string.hello_world);      if(!s1.equals(s2)){         Log.d("DIFFERENT LOCALE", i + ": "+ s1+" "+s2 +" "+ loc[i]);     } } 

It has one fault - you can check one value whether it has translation.

The dirty code above will print something like:

LOCALE(5667): 51: en_NZ LOCALE(5667): 52: uk_UA LOCALE(5667): 53: nl_BE LOCALE(5667): 54: de_DE DIFFERENT LOCALE(5667): 54: Hallo Welt! Hello world! de_DE LOCALE(5667): 55: ka_GE LOCALE(5667): 56: sv_SE LOCALE(5667): 57: bg_BG LOCALE(5667): 58: de_CH DIFFERENT LOCALE(5667): 58: Hallo Welt! Hello world! de_CH LOCALE(5667): 59: fr_CH LOCALE(5667): 60: fi_FI
