android - Change language settings (locale) for the device

Question

I know it's possible to have multiple languages in a single application through the res/string and depending on Locale. Here is a case (ANDROID) controling the user language

Now how can I change the language in the phone ? Like I'd do by Menu > Settings > Language & Keyboard > Select locale > languages

Is there some real code to access to these settings ? Or should I create intent for a shortcut to the language settings. Please post some code

Edit : With Locale class developer.android.com/intl/fr/reference/java/util/Locale.html

The constructor is at least Locale(String language) The input is language. How can you retrieve the current language used on the device ?

Answer 1

Not sure about setting it directly from the app, but if you want to send the user there to change it themselves, try this:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.settings", "com.android.settings.LanguageSettings");            
startActivity(intent);
