Will android application get message about system locale changes?

Question

In JNI method I use call to Java objects to get locale settings.

My JNI call is similar to Locale.getDefault() that I used to get it.

Will application be notified about system locale changes?

So, typical usecase:

1. Run my application.
2. In native code get locale from Locale.getDefault();
3. Change current system locale by settings menu on device.
4. In native code get locale from Locale.getDefault();

Will I get actual information about current locale in step 4?

Answer 1

An Intent is broadcast for this the ACTION_LOCALE_CHANGED should let you know when a change in the preferences has happened. However if you're calling it after its changed without having been notified, you'll still get the new locale information.

Answer 2

Will I get actual information about current locale in step 4?

Yes, I will.

But there is one issue:

If main activity blocked by native call , locale information will not change till the main activity not recive ACTION_LOCALE_CHANGED.
