Question

我对这个问题感到非常沮丧。我一直得到它，我无法弄清楚为什么。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)

在构建（ndk-build）或通过eclipse清理项目时，我一直遇到这个问题

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

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

Answer 1

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

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

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

另一种选择是明确添加路径，在call import-module之前添加以下行，例如：

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

请参阅this for other examples

Answer 2

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。我不得不在NDK / sources中移动ffmpeg文件夹，我能够毫无问题地构建它。

在导入路径中找不到带标签的模块（Android NDK）
