Hi RichardC~~ Thanks for your reply.
I am implement GPS hardware on my own platform and I have been create two files named Android.mk and gps_gn7560.c to implement gps interface defined in http://www.netmite.com/android/mydroid/cupcake/development/pdk/docs/gps.html. The libgps.so have created successfully but still have many questions. 1.I create gps_gn7560.c that refer to gps_qemu.c and gps.h(mentioned in http://www.netmite.com/android/mydroid/cupcake/development/pdk/docs/gps.html) but it seems that my function in gps_gn7560.c not called. ex: there is a function in gps_gn7560.c named gps_get_interface( void ) ====================================================================== const GpsInterface* gps_get_interface( void ) ====================================================================== and there is a function call in android_location_GpsLocationProvider.cpp ====================================================================== static jboolean android_location_GpsLocationProvider_is_supported (JNIEnv* env, jclass clazz) { if (!sGpsInterface) sGpsInterface = gps_get_interface(); return (sGpsInterface != NULL); } ====================================================================== I found that it does not call gps_get_interface() in my gps_gn7560.c instead of calling another gps_get_interface() defined in gps.cpp which provided by Android. How can I change it to call my gps_get_interface() 2.How to test GPS if gps is implemented successfully. I know there is a gpstest tool in Android but I don't know how to use it. Can someone tell me the detail about gpstest tool provided by Android. Anyway, I appreciate your reply and suggestion and I will do what you suggest.
