我对这个问题感到非常沮丧。我不断得到它，我不知道为什么。这是我在 src/jni 中的 Android.mk

LOCAL_PATH := $(call my-dir) 
include $(CLEAR_VARS)
LOCAL_MODULE    := tutorial01
LOCAL_SRC_FILES := tutorial01.c
LOCAL_LDLIBS := -llog -lz
LOCAL_SHARED_LIBRARIES := libavformat_static libavcodec_static libavutil_static 
include $(BUILD_SHARED_LIBRARY)
$(call import-module,ffmpeg-2.4.2/android/armv7-a)

这是我的 /jni/ffmpeg-2.4.2/android/armv7-a 中的 Android.mk

LOCAL_PATH:= $(call my-dir)
#static version of libavcodec
include $(CLEAR_VARS)
LOCAL_MODULE:= libavcodec
LOCAL_SRC_FILES:= lib/libavcodec.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
include $(PREBUILT_STATIC_LIBRARY)
#static version of libavformat
include $(CLEAR_VARS)
LOCAL_MODULE:= libavformat
LOCAL_SRC_FILES:= lib/libavformat.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
include $(PREBUILT_STATIC_LIBRARY)
#static version of libswscale
include $(CLEAR_VARS)
LOCAL_MODULE:= libswscale
LOCAL_SRC_FILES:= lib/libswscale.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
include $(PREBUILT_STATIC_LIBRARY)
#static version of libavutil
include $(CLEAR_VARS)
LOCAL_MODULE:= libavutil
LOCAL_SRC_FILES:= lib/libavutil.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
include $(PREBUILT_STATIC_LIBRARY)

通过eclipse构建（ndk-build）或清理项目时，我不断遇到这个问题

**** Clean-only build of configuration Default for project android-ffmpeg-tutorial01 ****

/Applications/adt-bundle-mac-x86_64-20130514/android-ndk-r10c/ndk-build clean

要使用import-module，您需要设置/导出NDK_MODULE_PATH指向导入模块的父文件夹路径的环境变量。

    $(call import-module,ffmpeg-2.4.2/android/armv7-a)

所以对于<parent-path>/ffmpeg-2.4.2/android/armv7-a, 设置/导出NDK_MODULE_PATH = parent-path

另一种选择是显式添加路径，在 之前添加以下行call import-module，例如：

    $(call import-add-path, parent-path)
    $(call import-module,ffmpeg-2.4.2/android/armv7-a)

有关其他示例，请参见此内容

我解决了！！我的问题是我的 ffmpeg 文件夹不在我的 NDK/sources 文件夹中。我必须在 NDK/sources 中移动 ffmpeg 文件夹，并且能够毫无问题地构建它。
