GPSd on Android/AOSP:
---------------------
The files in this path, as well as the Android.bp in the path below,
are used for building the GPSd client as a platform library for AOSP.
Three components are currently implemented;
Shared library, libgps (builds libgps.so)
Static library, libgps_static
Test client, gps_test (builds executable gps_test)
Build instructions:
-------------------
1) clone gpsd into your Android build tree at;
platform/external/gpsd
2) initialize your build environment for your target device;
cd platform/
. build/envsetup.sh
lunch
3) build the component;
m libgps
or
m gps_test
This will build the component and output it at;
platform/out/target/product/<device name>/vendor/
As a platform dependency:
-------------------------
You can add the components to your device's dependency list by adding
it to the PRODUCT_PACKAGES variable in one of your device's makefiles.
For example;
PRODUCT_PACKAGES += libgps gps_test
Following this, performing a full build for your device will
incorporate the component(s) into the vendor partition image for
your device.
Running gps_test:
-----------------
gps_test is an extremely simple test client that continually prints
fix and SV details to the console.
It accepts one parameter, which is the IP address or hostname of
a running instance of GPSd.
Building other components using libgps:
---------------------------------------
gps_test is a good starting point for building other components using
libgps. libgps can be added either as a shared object or static
linked. For use as a shared object, add "libgps" to the list of
shared_libs that your module depends on. For static, use
"libgps_static" in the list of static_libs.
Future work:
------------
I am currently in the process of writing a GNSS 1.1 HAL for Android
based on libgps. Once this is working, I will move on to getting
GPSd itself to build.
