1220024 - [GPS] Support of loading the gps config dynamically

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: General, defect)

Description

[Alphan Chen [:alchen]]

This bug is from bug 1201778 comment 56.

[Quote Bhavna Sharma's comment]
The need for loading the gps config dynamically i.e. 
loading the GPS_LOCK based on the SIM card (i.e. every carrier may have their own GPS_LOCK setting)
Say if SIM card is changed, and each carrier had their own GPS_LOCK config, then a hard coded GPS_LOCK set in gps.conf will not work.

This is needed so that OEM's do not have to care about setting a different GPS_LOCK as per carrier requirement. This support is needed from OS layer.

Hi Bhavna:

1. Besides GPS_LOCK, is there any other gps config we need to take care?
2. Will one carrier correspond to only one config set?

Hi Alphan,

You can refer to this function to see what all properties can be loaded and updated.
frameworks/base/services/core/java/com/android/server/location/GpsLocationProvider.java#subscriptionOrSimChanged

gps.h also provides an interface to update HAL with the new properties
Please refer to use of GnssConfigurationInterface on how the update is made to HAL.

I am also still trying to go through and understand the code.

I don't see GPS_LOCK related code in this file.

Is it only for Gnss but GPS?
