Android studio 1.5.1:无法找到属性'vectorDrawables'

Question

我正在使用Android Studio 1.5.1,Gradle 2.8和我的项目min sdk vserion:14,目标sdk版本:23.

所以,当我通过文档Google添加vectorDrawables配置时:添加了VectorDrawable支持库,我收到以下错误:

Error:(13, 0) Could not find property 'vectorDrawables' on ProductFlavor_Decorated{name=main, dimension=null, minSdkVersion=ApiVersionImpl{mApiLevel=14, mCodename='null'}, targetSdkVersion=ApiVersionImpl{mApiLevel=23, mCodename='null'}, renderscriptTargetApi=null, renderscriptSupportModeEnabled=null, renderscriptNdkModeEnabled=null, versionCode=25, versionName=1.0.25, applicationId=com.smsoft.alibaba, testApplicationId=null, testInstrumentationRunner=null, testInstrumentationRunnerArguments={}, testHandleProfiling=null, testFunctionalTest=null, signingConfig=null, resConfig=null, mBuildConfigFields={}, mResValues={}, mProguardFiles=[], mConsumerProguardFiles=[], mManifestPlaceholders={}}.

这是我的build.gradle文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.smsoft.alibaba"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 25
        versionName "1.0.25"
        vectorDrawables.useSupportLibrary = true
    }
    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-v7:23.2.0'
     compile 'com.android.support:design:23.2.0'
     compile 'com.android.support:support-v4:23.2.0'
     compile 'com.android.support:cardview-v7:23.2.0'
}

有谁知道如何解决这个问题？

感谢@Gabriele Mariotti表示我在gradle和gradle插件之间感到困惑.在阅读Compact Vector Drawables指令的添加时,我很困惑.

Answer 1

如果您使用的是Gradle插件的v2.0或更高版本,则必须使用:

android {
  defaultConfig {
    vectorDrawables.useSupportLibrary = true
  }
}

如果您使用的是Gradle插件的v1.5.0或更低版本,则需要将以下内容添加到您的应用中:build.gradle

android {
  defaultConfig {
    // Stops the Gradle plugin’s automatic rasterization of vectors
    generatedDensities = []
  }
  // Flag to tell aapt to keep the attribute ids around
  aaptOptions {
    additionalParameters "--no-version-vectors"
  }
}

不要将gradle与gradle插件混淆.检查build.gradle根文件夹(或模块内部)以获取gradle插件使用的版本(检查行classpath 'com.android.tools.build:gradle:1.5.0')

专门升级com.android.tools.build:gradle:1.5.0.

1. 编辑/build.gradle并设置:

   buildscript {
       ...
       dependencies {
           ...
           classpath 'com.android.tools.build:gradle:2.0.0'
           ...
       }
   }
   

2. 编辑/gradle/wrapper/gradle-wrapper.properties并设置:

   distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
   

3. 编辑您的模块'build.gradle并添加:

   android {
       ...
       defaultConfig {
           ...
           vectorDrawables.useSupportLibrary = true
       }
       ...
   }
