Question

在我的android应用中，编译该应用时出错。我正在最新的android studio中工作，并且使用Firebase UI Auth和Firebase数据库，所有版本都在应用程序级别成绩文件中相同，那么为什么我会收到此错误

错误：

Build.gradle错误所有com.android.support库都必须使用完全相同的版本规范（混合版本可能导致运行时崩溃）。找到版本28.0.0、27.1.0、27.0.2。示例包括com.android.support:animated-vector-drawable:28.0.0和com.android.support:exifinterface:27.1.0 less ...（⌘F1）有一些库，工具或库的组合不兼容或可能导致错误。一种不兼容的情况是使用不是最新版本的Android支持库版本进行编译（或者特别是低于目标targetSdkVersion的版本）。问题ID：GradleCompatible

build.gradle（项目：我的应用程序）

// 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:3.2.1'
        classpath 'com.google.gms:google-services:4.0.1'

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

allprojects {
    repositories {
        google()
        jcenter()
        maven{
            url="com.google.maven"
        }
    }
}

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

build.gradle（模块：应用）

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


android {
    compileSdkVersion 28

Answer 1

添加：

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

在build.gradle（模块：应用）文件中的dependencies{}之后

Answer 2

只需尝试用抱怨的较低版本重新添加所有依赖项，例如add

implementation 'com.android.support:exifinterface:28.0.0'

同步并编译，如果有的话，也添加它。让我知道会发生什么。

Lcom / google / firebase / FirebaseApp类中没有虚拟方法zzbqo（）Z；或其超一流
