Google Cloud API APK 中复制的重复文件 com/google/cloud/project.properties

Question

这是我的 build.gradle(app) 文件，当我尝试同步此文件时，出现 8 个警告，当我尝试运行此应用程序时，几乎没有警告和错误提示有一个Duplicate file Exception。

我正在尝试在我的 android 应用程序

中实施 Google 云数据存储

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.appspot.myapp"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    configurations.all {
        resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
    }
    packagingOptions {

        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LGPL2.1'

    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:design:25.3.1'
    testCompile 'junit:junit:4.12'
    compile group: 'com.google.cloud', name: 'google-cloud-datastore', version: '+'
}

点击“立即同步”后，我收到以下警告：

Answer 1

排除那些重复项应该可以消除该错误

compile('com.google.cloud:google-cloud-datastore:1.0.0-rc2') {
    exclude group: 'org.json'
    exclude group: 'org.apache.httpcomponents'
}

但是 Android 从 Android 6 开始弃用了 SDK 中的 Apache HTTP 组件。

所以，我真的认为你应该 setup Endpoints 因为

Google Cloud Endpoints [provides] automated Java object marshalling/unmarshalling to JSON, generation of strongly-typed client libraries that can be called from your Android app, built-in authentication support and so on.

我认为 link 部署了一个 Java 后端，但我已经将其与 Python App Engine 应用程序一起使用，只是不记得它是如何工作的。
