First, thank you for your work. I tested this library and it works great. But the library minSdkVersion is set to 16. I am working on an application that has millions of user supporting minSdkVersion 15. I tried to override this in manifest but as I expected, I got runtime error in an emulator on Api version 15.

NoSuchMethodError: android.content.res.Configuration.setLocale

This happens in your LocalizationContext Class. Configuration.setLocale() is added in Api 17 and previously this had been done with Configuration.locale = .... If this is the only reason to set minSdk to 17, could you consider supporting Api version 15?

Also a question, if setLocale is defined in Api 17, how your library supports Api 16?
