Question

我的应用程序出现问题，每当我尝试向其中添加Firestore时，构建gradle即可工作，但是在尝试运行该程序后，它崩溃并给出以下消息：

错误：程序类型已经存在：com.google.common.base.AbstractIterator $ State

或

错误：程序类型已经存在：com.google.common.base.Absent

和其他一些相同类型的错误“错误：类型已经存在”

这是我的gradle文件：

应用插件：“ com.android.application”

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.myApp.name"
        minSdkVersion 23
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.google.api-client:google-api-client:1.23.0'
    implementation 'com.google.http-client:google-http-client-gson:1.23.0'
    implementation 'com.firebaseui:firebase-ui-auth:4.1.0'
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support.constraint:constraintlayout:1.1.3'
    implementation 'com.google.firebase:firebase-auth:16.0.1'
    implementation 'com.google.firebase:firebase-core:16.0.1'
    implementation 'com.google.firebase:firebase-firestore:17.0.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

}

apply plugin: 'com.google.gms.google-services'


configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '28.0.0'
            }
        }

    }
}

我尝试将所有3个Firebase实现版本都设置为16.0.0，但给了我相同的错误

项目收益如下：

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        classpath 'com.google.gms:google-services:4.1.0'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

如果有人遇到与我相同的问题，这就是我找到的解决方案：

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '28.0.0'
            }
        }
        if (requested.group == 'com.google.android.gms') {
            details.useVersion '12.0.1'
        }
        if (requested.group == 'com.google.firebase') {
            details.useVersion '12.0.1'
        }
    }
}

将Firestore和Firebase Auth / Core一起使用时出现问题
