How to run onLoadConfig()

[TazKilla]

Hello all,

I can't update my CarrierConfig.

Even if I follow the official documentation, I can't run my overrided method onLoadConfig(), in my MainActivity, via notifyConfigChangeForSubId().
No logs are displayed by this method (onLoadConfig()) that I override, even after reboot, which have to run this method, no ?
Have I to implement some kind of service just after the boot, to bypass the native onLoadConfig method ?

Thanks in advance for your help.
