<a name="androidGpsIntroduction"></a><h2>Introduction</h2>
|
|
|
|
<p>Android defines a user space C abstraction interface for GPS hardware. The interface header is defined in <code>include/hardware/gps.h</code>. In order to integate GPS with Android, you need to build a shared library that implements this interface. </p>
|

|
|
<a name="androidGPSBuildingDriver"></a><h2>Building a GPS Library</h2>
|
|
|
|
<p>To implement a GPS driver, create a shared library that implements the interface defined in <code>gps.h</code>. You must name your shared library <code>libgps.so</code> so that it will get loaded from <code>/system/lib</code> at runtime. Place GPS sources and Android.mk in <code>partner/acme/chipset_or_board/gps/</code> (where "acme" is your product name and "chipset_or_board" is your hardware target).</p>
|
|
|
|
<p>The following stub <code>Android.mk</code> file ensures that <code>libgps</code> compiles and links to the appropriate libraries:</p>

LOCAL_PATH := $(call my-dir)
