如何配置build.gradle

Question

我正在尝试添加cppFlags，但始终报告错误：

"Error:(16, 0) Could not find property 'cppFlags' on com.android.build.gradle.internal.dsl.NdkOptions_Decorated@44658d55. <a href="openFile:/Users/liut1/Documents/Projects/Android/GitSourceCode/VideoWall/app/build.gradle">Open File</a>"

请帮助我，谢谢！

这是我的等级：

1. 最重要的

    // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.1.2' // classpath 'com.android.tools.build:gradle-experimental:0.4.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() } } task clean(type: Delete) { delete rootProject.buildDir } 

2. 应用程式gradle

     apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion "23.0.3" defaultConfig { applicationId "andrewl.videowall" minSdkVersion 15 targetSdkVersion 23 versionCode 1 versionName "1.0" ndk { moduleName = "HelloARVideoNative" // cppFlags.add("-I${file("include")}".toString()) cppFlags.add("-DANDROID") cppFlags.add("-fexceptions") cppFlags.add("-frtti") stl = "gnustl_static" ldLibs "log","GLESv2" } } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } sourceSets { main { java.srcDirs = ['src/main/java', 'src/main/java-gen'] jniLibs.srcDirs = ['libs'] } } productFlavors { create("arm") { ndk.with { abiFilters.add("armeabi-v7a") } } } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:23.4.0' compile files('libs/greendao-1.3.7.jar') } 

3. Gradle包装器

Answer 1

看看这个。 此示例包含在cpp支持的应用程序中所需的配置。

ndk {
    moduleName = 'hello-jni'
    toolchain = 'clang'
    CFlags.addAll(['-Wall'])
}
