- Since the "Mobile-Data Details Settings" (NETWORK_OPERATOR_SETTINGS) will query Carrier-Config around 70 times during launching, use the Carrier-Config cache to reduce 69 times to speed up the launching time.
- It takes about 3ms to query a Carrier-Config each time.
- Create a singleton class to share the Carrier-Config for all
sub-settings.
