java - Android studio3.1.3-Windows 10 中的 Gradle 项目同步失败

Question

我正在尝试在我的 Windows 10 上创建一个 Android Studio 项目，但我的 Android.mk 文件出现了一些错误。ffmpeg文件夹不在 Sdk 文件夹中，我不明白为什么。我正在使用默认的 SDK 位置。怎么了？

SDK：C:\Users\danilo\AppData\Local\Android\Sdk

JDK：C:\Program Files\Android\Android Studio\jre

NDK：C:\Users\danilo\AppData\Local\Android\Sdk\ndk-bundle

安卓.mk：

LOCAL_PATH := $(call my-dir)
CVROOT:= C:\Users\danilo\Desktop\appandroid\OpenCV-android-sdk\sdk\native\jni
OPENCV_LIB_TYPE:=STATIC
include $(CVROOT)/OpenCV.mk
# Path to ffmpeg
# Has to be built and Android.mk written (libavformat, libavcodec, libavutil, libswscale needed)
# See https://enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/
FFMPEG_PATH := ../../../../sources/ffmpeg-2.2.3/android/arm

# Path to OpenCV
# http://sourceforge.net/projects/opencvlibrary/files/opencv-android/3.1.0/OpenCV-3.1.0-android-sdk.zip/download
OPENCV_PATH := C:\Users\danilo\Desktop\appandroid\OpenCV-android-sdk

LOCAL_SRC_FILES := FFmpegEncoder.cpp com_prouast_heartbeat_FFmpegEncoder.cpp
