Is there any other GNSS framework and hal code to be modified?

I have read <AirPrime - Android RIL Integration Guide.pdf>,and I have some questions to ask.
I don’t know if this is enough for android framework to get location fix.
Is there any other GNSS framework and hal code to be modified?

I have also read <SierraWirelessLocationBasedServicesCDMAr2.pdf>,as it said,I have four options
to get location fix from Sierra Wireless module,Application programming interfaces,CnS commands,
AT commands,NMEA interface.So, which option does <AirPrime - Android RIL Integration Guide.pdf> use?

As you know,the call flow of Qcom is
startNavigating(GNSSLocationProvider.java) -> native_start() -> android_location_GnssLocationProvider_start(Native)
-> HIDL -> gps.default.so.
So,when we use Sierra WP7603,not qcom modem, if the call flow is the same? Do we just need to replace gps.default.so with yours?

Hi,

WP76XX was using NMEA interface to get fix.
Yes, you need copy our gps so file to target system. and rename it with gps.default.so

Thanks,
