如何编译进系统:
1. place ublox/gps to <android4.3>/hardware/
2. vim <android4.3>/device/fsl/imx6/imx6.mk
add the gps.default which name is the same to LOCAL_MODULE:=gps.default in ublox/gps/hal/Android.mk
if LOCAL_MODULE:=gps.default is not set in the imx6.mk , that will not complie the ulox source code.
In this case, you can enter directory of ublox source code and use mm -B or mmm
#source build/envsetup.sh
