Change language programatically in Android

Question

Is it possible to change the language of an app programmatically while still using Android resources?

If not, is it possible to request a resource in an specific language?

I would like to let the user change the language of the app from the app.

It's possible. You can set the locale. However, i would not recommend that. We've tried it at early stages, it's basically fighting the system. We have same requirement for changing language, but decided to settle to the fact that UI should be same as phone UI. It was working via setting locale but was too buggy. And you have to set it every time you enter activity ( each activity ) from my experience. here is a code if you still need this ( again, i don't recommend that )

    Resources res = context.getResources();
    // Change locale settings in the app.
    DisplayMetrics dm = res.getDisplayMetrics();
    android.content.res.Configuration conf = res.getConfiguration();
    conf.locale = new Locale(language_code.toLowerCase());
    res.updateConfiguration(conf, dm);

If you have language specific content - you can change that base on the setting.
