I try to force the locale in my app to one the user specified. As this may be used to demonstrations, I want to change the language/locale in the app and not anytime for the whole device.
I looked around SO and tried to use every hint I found here. The result: I can restart my test activity with the new language, but if I change the orientation, the locale will always be reseted to the device one.
I uploaded a minimalistic project so you can reproduce my issue. Please ignore the shrinking of the UI, it's not important :)
Is the reset of the locale occurring because your Activity is being restarted on orientation change?
If so, you can intercept or prevent orientation changes: Activity restart on rotation Android
