Android NDK: Aborting stop?

问题:

I am working on ffmpeg for android. I have successfully compile ffmpeg-2.0.1 after that I make Android.mk file in my NDK's sources/ffmpeg-2.0.1/android/arm as

      LOCAL_PATH:= $(call my-dir)

      include $(CLEAR_VARS)

      LOCAL_MODULE:= libavcodec

      LOCAL_SRC_FILES:= lib/libavcodec-55.so

       LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

      include $(PREBUILT_SHARED_LIBRARY)

After that make android project and in android project Android.mk file is as

  LOCAL_PATH := $(call my-dir)

    include $(CLEAR_VARS)

   LOCAL_MODULE    := tutorial01
   LOCAL_SRC_FILES := tutorial01.c
   LOCAL_LDLIBS := -llog -ljnigraphics -lz 
   LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil

   include $(BUILD_SHARED_LIBRARY)
    $(call import-module,ffmpeg-2.0.1/android/arm)

but showing a problem

See the Android.mk structure firstly.

Need change Android.mk file like this :

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE    := ffmpeg
LOCAL_SRC_FILES := libs/ffmpeg.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := final_ffmpeg
LOCAL_SRC_FILES := ffmpeg.cpp
LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog
LOCAL_PREBUILTS := libs/ffmpeg.so
#libavformat libavcodec libswscale libavutil
include $(BUILD_SHARED_LIBRARY)

p/s : I also get the Android NDK : Aborting problem as you when put data together like this :

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE:= ffmpeg
LOCAL_SRC_FILES:= libs/ffmpeg.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := ffmpeg
LOCAL_SRC_FILES := ffmpeg.cpp
LOCAL_SHARED_LIBRARIES := ffmpeg
include $(BUILD_SHARED_LIBRARY)

This problem happens when LOCAL_MODULE name is duplicated.

The result will help you :

It still be exactly when you need call the C++ function in C++ file from Java file.

I run into a similar problem when I tried to build HelloComputeNDK sample with NDK64-Linux-r10.

Then I notice that NDK64-Linux-r10 only have Android-L platform, so I download NDK32-Linux-R10, and merge it with NDK64-Linux-r10.

It goes well for me.

U can download NDK32-Linux-r10 here: https://developer.android.com/tools/sdk/ndk/index.html
