错误：向Android Studio项目添加Firebase存储依赖项时出错？

我在Android Studio中创建了一个Firestore项目。我已经在其中实现了Firebase授权，并且工作非常好。我能够将文档推送到Firestore数据库

但现在，我正在尝试添加功能，使用该功能我可以将媒体/图像存储到Firebase存储，但当我将此依赖项添加到应用程序的build.gradle文件时，我遇到以下错误：

添加了依赖项：

implementation 'com.google.firebase:firebase-storage:16.0.1'

这是我得到的错误：

Could not find firebase-common.jar (com.google.firebase:firebase-common:16.0.0).
Searched in the following locations:https://jcenter.bintray.com/com/google/firebase/firebase-common/16.0.0/firebase-common-16.0.0.jar

仅供参考，在我的项目中，我已经有了这种配置：

classpath 'com.android.tools.build:gradle:3.1.3'

及

当我只是将firebase存储依赖项添加到我的Android项目中时，我找不到哪里出了问题

这是我的应用程序级别build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "com.firebase.example"

}

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

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

这是我的模块级build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "com.firebase.example"

您是否已将这些添加到根级别的gradle文件中

buildscript {

    dependencies {

        classpath 'com.google.gms:google-services:4.0.1' 
    }
}

allprojects {

    repositories {

        google() 
    }
}

---

您必须在根级别的build.gradle文件上添加

依赖项{classpath'com.google.gms:google services:4.0.1'}

和

存储库{google（）}

。你加上去了吗？此外，请提供完整的build.gradle文件以了解您的问题。

升级以下内容：

 implementation 'com.google.firebase:firebase-firestore:16.0.0'
 implementation 'com.google.firebase:firebase-auth:15.1.0'

为此：

 implementation 'com.google.firebase:firebase-firestore:17.0.2'
 implementation 'com.google.firebase:firebase-auth:16.0.2'

查看此处了解更多信息：

您也可以使用firebase助手设置

伙计们，我成功了。您可以简单地比较我的新gradle文件。问题在于谷歌服务库和gradle版本之间存在冲突。所以，我创建了一个新的项目，只是像这样再次添加了依赖项，它成功了

因此，我从app/build.gradle:

implementation 'com.google.android.gms:play-services-auth:15.0.1'

classpath 'com.google.android.gms:play-services-base:15.0.1'

classpath 'com.google.gms:google-services:4.0.1'

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

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:4.0.1' // google-services plugin

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

allprojects {

很好，您使用的auth版本是什么？应用程序gradle

implementation'com.google.firebase:firebase-firestore:16.0.0'implementation'com.google.firebase:firebase-auth:15.1.0'implementation'com.google.firebase:firebase-auth:15.1.0'implementation'com.google.firebase:firebase-storage:16.0.1'implementation'com.google.android.gms:play services auth:15.0.1'

在根目录gradle

classpath'com.google.android.gms:play services base:15.0.1'classpath'com.google.gms:google services:4.0.1'

这对我来说效果很好它成功生成了BuildBuild将firebase存储添加到这个配置中给我错误：无法解决：firebase Common你的应用程序gradle和我的应用程序gradle之间的区别在于

targetSdkVersion:27

和

compileSdkVersion 27

以及在根级别

classpath'com.android.tools.build:gradle:3.2.0-beta01'

检查这是否能产生差异，我尝试了这一点，但在构建项目时仍然遇到错误。未能解决：firebase数据库集合未能解决：protolite著名类型SADD

implementation'com.google.firebase:firebase数据库：16.0.1'

添加上述依赖项，然后清理并重建Bijal，谢谢。这已经存在了，但我仍然会出错。
