java - Android getting wrong localization strings -
i'm writing app want add multiple language support. have english , bulgarian, when start activities has default values instead of localized. i'm setting manually location via overriding attachbasecontext. when change language english, again bulgarian (without leaving activity, recreating it) working properly. when start app (in mainactivity) working properly. strings in string.xml under values , values-bg folders.
