Re: [gpsd-dev] RFC: GPSd on Android as a system service

[A.S.]

I have had the opportunity to clean up and test the additions needed to make libgps build and work on Android.

https://gitlab.com/aserbinski/gpsd/tree/android

Three parts to it;

1) shared library. This will be the typical approach to using it.

2) static library.

3) very simple test client.

The test client uses the static version of libgps, since it simplifies running it on a normal device where you don't have access to the system or vendor partitions.

Build instructions;

check out the gpsd respository to platform/external/gpsd

lunch your device

m libgps or gpsdtest

That will create the libgps.so in the vendor/lib/ and vendor/lib64/, or it will create gpsdtest in vendor/bin/

My goal is to use GPSd to provide location services for Android.

This project can be broken down into three phases;

1) Building the libgps client library,

2) Building a GNSS HAL that uses libgps,

3) Building GPSd.

The Android build system is sufficiently unique to require a change in the build process. For example, it is not possible to use scons to generate configuration files, specifically, gpsd_config.h and gps_maskdump.c. This makes it necessary to generate those files in advance.

The following makes it possible to build libgps for Android using the Android build system:

Further, I have begun implementation of a GNSS 1.1 HAL that leverages libgps, here;

https://gitlab.com/aserbinski/gpsd/commit/81899450f6f8346ef6e2d630eb4c19d6bb374e33

Note that neither of these is actually tested beyond successful compile yet.

Thanks,
