Wie build.gradle konfigurieren

Question

Ich versuche CPPFLAGS hinzufügen, aber immer Fehler melden:

"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>"

Bitte helfen Sie mir, danke!

Hier sind meine gradles:

1. oben gradle

   // 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. App 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 Wrapper

   #Mon Dec 28 10:00:20 PST 2015 
   distributionBase=GRADLE_USER_HOME 
   distributionPath=wrapper/dists 
   zipStoreBase=GRADLE_USER_HOME

Answer 1

Schauen Sie sich das an. Dieses Beispiel enthält die Konfiguration, die Sie in Ihrer cpp-unterstützten Anwendung benötigen.

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