Question

我正在使用Google API，因此我将此脚本添加到 build.gradle 文件（在我的项目中的 app / 文件夹中）但我收到错误＆＃ 34; 无法解决：com.google.apis ：请帮忙。

apply plugin: 'com.android.application'

android {

compileSdkVersion 22
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId "com.example.gmailquickstart"
    minSdkVersion 11
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),
                'proguard-rules.pro'
    }       
}

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.google.android.gms:play-services:7.3.0'
    compile 'com.google.api-client:google-api-client:1.20.0'
    compile 'com.google.api-client:google-api-client-android:1.20.0'
    compile 'com.google.api-client:google-api-client-gson:1.20.0'
    compile 'com.google.apis:google-api-services-gmail:v1-rev29-1.20.0' 
}

您希望在build.gradle中使用此代码：

familyType <- function(relation, gender) {
  polygamy = sum(relation == 2, na.rm = TRUE)
  headgender = gender[relation == 1]
  polygamy = as.integer(levels(polygamy))[polygamy]
  headgender = as.integer(levels(headgender))[headgender]
  if(polygamy == 0) {
    if(headgender == 1){
      return (1L)
    } else {
      return (2L)
    }
  } else if(polygamy == 1){
    if(headgender == 1){
      return (3L)
    } else {
      return (4L)
    }
  } else if(polygamy > 1) {
    return (5L)
  }
}

tbl[, type:=familyType(Relation.to.Head, Gender), by=Id]

编辑：根据参考资料，你也可以在那里下载jar文件以避免引用maven，如果你愿意的话。
