Hello, all. I'm still new to the NDK and Eclipse, so this is probably an easy question. I have source code for several libraries that I want to have built into libs/armeabi/libNAME.so. Reading the documentation, it seems like all I should have to do is put the libraries into individual folders under the jni folder, create an Android.mk file in jni which has a call to "include $(call all-subdir-makefiles)", and another Android.mk in the sub-folder which has a call to "include $(BUILD_SHARED_LIBRARY)" I think these files are correct, so I'm not sure what I'm missing to have Eclipse/NDK actually build the libraries. For reference, the Android.mk file located in jni is: Code (Text): # If SDL_Mixer should link to libMAD SDL_MIXER_USE_LIBMAD := ifneq ($(strip $(filter mad, $(COMPILED_LIBRARIES))),) SDL_MIXER_USE_LIBMAD := 1 endif ifneq ($(findstring -crystax,$(TARGET_CC)),) $(info Building with CrystaX toolchain - RTTI and exceptions enabled, STLPort disabled) CRYSTAX_TOOLCHAIN=1 endif include $(call all-subdir-makefiles) And an example of an Android.mk file for one of the libraries, located in a sub-folder under jni: Code (Text): LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := xml2 LOCAL_CFLAGS := -Os -I$(LOCAL_PATH) -I$(LOCAL_PATH)/include LOCAL_CPP_EXTENSION := .cpp LOCAL_SRC_FILES := \ SAX.c entities.c encoding.c error.c \ parserInternals.c parser.c tree.c hash.c list.c xmlIO.c \ xmlmemory.c uri.c valid.c xlink.c HTMLparser.c HTMLtree.c \ debugXML.c xpath.c xpointer.c xinclude.c nanohttp.c nanoftp.c \ DOCBparser.c catalog.c globals.c threads.c c14n.c xmlstring.c \ xmlregexp.c xmlschemas.c xmlschemastypes.c xmlunicode.c \ xmlreader.c relaxng.c dict.c SAX2.c xmlwriter.c legacy.c \ chvalid.c pattern.c xmlsave.c xmlmodule.c schematron.c \ triostr.c trio.c trionan.c LOCAL_SHARED_LIBRARIES := LOCAL_STATIC_LIBRARIES := LOCAL_LDLIBS := -lz -ldl include $(BUILD_SHARED_LIBRARY) Let me know if you require any further information (sorry if I've left out something obvious).
