React Native Camera导致gradle构建错误

Question

我在Android上遇到了react-native-camera的问题.它现在正常工作大约一个星期,突然间,Gradle不会构建出现以下错误:

Error:Execution failed for task ':react-native-camera:processReleaseResources'.
> Error: more than one library with package name 'com.google.android.gms.license'

从我收集的内容来看,这是由com.google.android.gms多次加载引起的.我按照RNCamera文档进行操作,确保我的Gradle文件匹配.

Android设备/应用/的build.gradle:

android {
  compileSdkVersion 23
  buildToolsVersion "23.0.1"

  defaultConfig {
    applicationId "com.phase1"
    minSdkVersion 16
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    ndk {
        abiFilters "armeabi-v7a", "x86"
    }
  }
  splits {
    abi {
        reset()
        enable enableSeparateBuildPerCPUArchitecture
        universalApk false  // If true, also generate a universal APK
        include "armeabi-v7a", "x86"
    }
  }
  buildTypes {
    release {
        minifyEnabled enableProguardInReleaseBuilds
        proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
    }
  }
  // applicationVariants are e.g. debug, release
  applicationVariants.all { variant ->
    variant.outputs.each { output ->
        // For each separate APK per architecture, set a unique version code as described here:
        // http://tools.android.com/tech-docs/new-build-system/user-guide/apk-splits
        def versionCodes = ["armeabi-v7a":1, "x86":2]
        def abi = output.getFilter(OutputFile.ABI)
        if (abi != null) {  // null for the universal-debug, universal-release variants
            output.versionCodeOverride =
                    versionCodes.get(abi) * 1048576 + 
  defaultConfig.versionCode
        }
    }
  }
}

dependencies {
  compile (project(':react-native-camera')) {
    exclude group: "com.google.android.gms"
    compile 'com.android.support:exifinterface:27.+'
  }
  //compile project(':react-native-camera')
  compile fileTree(dir: "libs", include: ["*.jar"])
  compile "com.android.support:appcompat-v7:23.0.1"
  compile "com.facebook.react:react-native:+"  // From node_modules
}

安卓/ settings.gradle:

rootProject.name = 'Phase1'
include ':react-native-camera'
project(':react-native-camera').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-camera/android')
include ':app'

安卓/的build.gradle:

 // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
  repositories {
    jcenter()
    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:2.2.3'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
  }
}

allprojects {
  repositories {
    mavenLocal()
    jcenter()

    maven { url "https://jitpack.io" }
    maven {
        // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
        url "$rootDir/../node_modules/react-native/android"
    }
    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
  }
}

以下是外部库中的所有com.google.android.gms条目,我没有看到任何重复项并在此处尝试了所有答案Gradle:错误:包含名称为"com.google.android.gms"的多个库

我已经尝试删除com.android.support:appcompat-v7版本,创建一个新项目,卸载并重新安装Android SDK Build Tools(23.0.1,25.0.2,26.0.1,26.0.2,27.0.3)& Android支持存储库,已经没有想法.我正在使用Android Studio 3.0.1,gradle-2.14.1

一旦我从Gradle文件中删除相机refs,项目构建正常并按预期工作.所以我现在很困惑.任何建议将不胜感激.

这是因为谷歌服务版本更新(12.0.0).您应该通过编辑android/build.gradle文件将其指回11.8.0:

def googlePlayServicesVersion = '11.8.0'

allprojects {
  configurations.all {
    resolutionStrategy {
      eachDependency { DependencyResolveDetails details ->      
        if (requested.group == 'com.google.android.gms') {
          details.useVersion "$googlePlayServicesVersion"
        }
        if (requested.group == 'com.google.firebase') {
          details.useVersion "$googlePlayServicesVersion"
        }
      }
    }
  }
}
