我正在尝试使用OpenCV4Android + Android Studio + NDK制作Android应用程序。
我尝试了多种解决方案，但在尝试构建应用时仍然出现以下错误：

:app:ndkBuild FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:ndkBuild'.
> A problem occurred starting process 'command 'C:\Users\Mansi_PC\Downloads\android-ndk-r10e\ndk-build.cmd'
这是我的Gradle文件：
import org.apache.tools.ant.taskdefs.condition.Os
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.androidsrc.facedetection"
minSdkVersion 19
targetSdkVersion 23
versionCode 1
versionName "1.0"
sourceSets.main {
// jniLibs.srcDir 'src/main/libs' //set .so files directory to libs
jni.srcDirs = [] //disable automatic ndk-build call
}
project.ext.versionCodes = ['armeabi': 1, 'armeabi-v7a': 2, 'arm64-v8a': 3, 'mips': 5, 'mips64': 6, 'x86': 8, 'x86_64': 9]
//versionCode digit for each supported ABI, with 64bit>32bit and x86>armeabi-*
android.applicationVariants.all { variant ->
// assign different version code for each output
variant.outputs.each { output ->
output.versionCodeOverride =
project.ext.versionCodes.get(output.getFilter(com.android.build.OutputFile.ABI), 0) * 1000000 + defaultConfig.versionCode
}
}
// call regular ndk-build(.cmd) script from app directory
task ndkBuild(type: Exec) {
if (Os.isFamily(Os.FAMILY_WINDOWS)) {
commandLine 'C:\\Users\\Mansi_PC\\Downloads\\android-ndk-r10e\\ndk-build.cmd', '-C', file('src/main/jni').absolutePath
} else {
commandLine 'C:\\Users\\Mansi_PC\\Downloads\\android-ndk-r10e\\ndk-build', '-C', file('src/main/jni').absolutePath
}
}
tasks.withType(JavaCompile) {
compileTask -> compileTask.dependsOn ndkBuild
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.0'
compile project(':libraries:opencv')
}
这是我的Android.mk
LOCAL_PATH := $(call my-dir)
#OPENCV_CAMERA_MODULES:=off
#OPENCV_INSTALL_MODULES:=off
#OPENCV_LIB_TYPE:=SHARED
include F:\softwares\opencvandroid\OpenCV-android-sdk\sdk\native\jni\OpenCV.mk

include $(BUILD_SHARED_LIBRARY)
P.S。 - 我在local.properties文件中设置了ndk路径。 另外，在gradle.properties中我有＆＃34; android.useDeprecatedNdk = true＆＃34;
我尝试了所有可能的解决方案 谁能告诉我我做错了什么？
