Desdeeste tutorial.

veo que tengo una biblioteca estática pre-construida llamadastackoverflow.a y tienestackoverflow.h

Ahora quiero usar la función de esa biblioteca estática en

ndk_demo.c // ese tutorial tiene este archivo

por eso dentrondk_demo.c Yo he añadido

<code>#include 'stackoverflow.h'  
</code>

Editar

<code>inside `android-ndk-r7c`

                          Android.mk          libstackoverflow.a
</code>

AhoraAplicación.mk

<code>APP_PROJECT_PATH := $(call my-dir)/project
APP_MODULES      := ndk_demo stackover
</code>

Ahorajni / Android.mk

<code>include $(call all-subdir-makefiles)
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := ndk_demo
LOCAL_SRC_FILES := ndk_demo.c
LOCAL_STATIC_LIBRARIES := stackover
include $(BUILD_SHARED_LIBRARY)
</code>

ahorajni / lib / Android.mk

<code>   LOCAL_PATH := $(call my-dir)
   include $(CLEAR_VARS)
   LOCAL_MODULE := stackover
   LOCAL_SRC_FILES := libstackoverflow.a
   include $(PREBUILT_STATIC_LIBRARY)
   LOCAL_PATH := $(call my-dir)
</code>

Ahora desdeandroid-ndk-r7c directorio ejecuto

<code>make APP=ndk_demo
</code>

me muestra un error como

<code>Android NDK: Building for application 'ndk_demo'    
make: *** No rule to make target `build/core/ndk_demo.c', needed by `out/apps/ndk_demo/armeabi/objs/ndk_demo/ndk_demo.o'.  Stop.
</code>

¿Por qué esto está sucediendo?

si yo comento

<code>#include $(call all-subdir-makefiles)
</code>

esto dejni/Android.mk entonces muestra el siguiente error

<code>Android NDK: Building for application 'ndk_demo'
