Thanks David, I will try to modify my codes as you said. I will check if there is another module called gps_hardware, and i think the second reason may be the key as you have said.
I will check and tell you the result,thanks again. 2009/3/20 David Turner <di...@android.com> > Ah, another reason is to generate libfoo.so, you must name use > "LOCAL_MODULE := foo" + "include $(BUILD_SHARED_LIBRARY)" > using "LOCAL_MODULE := libfoo" will probably result in the generate of > "liblibfoo.so" or something, and the build system might not like it. > > I'm just speculating though. > > 2009/3/20 David Turner <di...@android.com> > >> It might be that there is already another module named gps_hardware >> somewhere in the build process, and that the error message is related to >> that.
