我都有Android ndkbuild不是抄袭我的共享库的中间体/ ndkbuild文件夹中的一个问题。我创建了我的模块在Android.mk这样的：的Android NDK产生错误的命令

Android.mk

LOCAL_PATH := $(call my-dir) 
include $(CLEAR_VARS) 
EXT_LIB_ROOT := $(LOCAL_PATH)/../prebuilt/dcmtk 

LOCAL_MODULE := ofstd 
LOCAL_SRC_FILES := $(EXT_LIB_ROOT)/ofstd/lib/$(TARGET_ARCH_ABI)/libofstd.so 
LOCAL_EXPORT_C_INCLUDES := $(EXT_LIB_ROOT)/ofstd/include 
include $(PREBUILT_SHARED_LIBRARY) 

include $(CLEAR_VARS) 
LOCAL_MODULE := oflog 
LOCAL_SRC_FILES := $(EXT_LIB_ROOT)/oflog/lib/$(TARGET_ARCH_ABI)/liboflog.so 
LOCAL_EXPORT_C_INCLUDES := $(EXT_LIB_ROOT)/oflog/include 
LOCAL_SHARED_LIBRARIES := ofstd 
include $(PREBUILT_SHARED_LIBRARY)

它建立和产生的命令是：

D:\android-sdk\ndk-bundle\\build\ndk-build.cmd NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=C:\dev\trunk\myApp\app\Android.mk NDK_APPLICATION_MK=C:\dev\trunk\myApp\app\Application.mk APP_ABI=x86 NDK_ALL_ABIS=x86 NDK_DEBUG=1 APP_PLATFORM=android-21 NDK_OUT=C:/dev/trunk/myApp/app/build/intermediates/ndkBuild/debug/obj NDK_LIBS_OUT=C:\dev\trunk\myApp\app\build\intermediates\ndkBuild\debug\lib APP_SHORT_COMMANDS=false LOCAL_SHORT_COMMANDS=false -B -n

现在，从日志的输出：

不幸的是，没有文件被复制或生成。通过从命令行运行相同的命令，结果是相同的。但是，如果我们在命令结束跳过-n标志，命令成功与文件复制完成。所以，我的问题是如何省略-n，什么是该标志的目的是什么？我正在使用最新的稳定ndk版本。

检查local.properties项目文件夹中的文件的路径NDK。它显示了用于构建makefile的ndk-bundle路径。
```
ndk.dir=/Users/../Library/Android/sdk/ndk-bundle 
```

检查gradle文件中的构建脚本。该脚本显示了共享库应位于：

sourceSets.main { 
    jni.srcDirs = [] 
    jniLibs.srcDir 'src/main/libs' 
}

，这表明生成文件路径NDK建设：

externalNativeBuild { 
    ndkBuild { 
     path 'src/main/jni/Android.mk' 
    } 
}

检查我的另一个答案也是，也许它会帮助你。 Linking shared libraries

我明明宣布ndkBuild和NDK工具路径，因为它编译和执行生成文件的脚本。我试图设置jniLibs.srcDir“的src/main /库”，但我不知道什么是应该做的，虽然 –

@NumLock你尝试与终端建设？只需转到jni文件夹，然后运行ndk-build。如果它构建共享库，然后再次检查你的gradle脚本。 – JavadKhan

我用Windows命令行，正如我所说，NDK-建设将文件复制到相应的目录，但只有当我跳过-n标志 –

的Android NDK产生错误的命令

Android.mk
