java - 为什么我在添加 Firebase 连接时在实现“com.android.support:appcompat-v7:28.0.0”时出现错误？

问题描述

当我修改我的 build.gradle 文件以使用 Firebase 插件时，它在实现“com.android.support:appcompat-v7:28.0.0”时显示错误

我已经将 google-services.json 文件添加到我的 Android 应用程序模块根目录中。

我的错误：问题 ID= Gradle 兼容

所有 com.android.support 库必须具有完全相同的版本规范...找到版本 28.0.0、26.1.0。示例包括 com.android.support:animated-vector-drawable:28.0.0 和 com.android.support:support-media-compat:26.1.0

我试图将其注释掉：

//noinspection GradleCompatible

implementation 'com.android.support:appcompat-v7:28.0.0'

但它也无法与firebase服务器通信

apply plugin: 'com.android.application'

android {
compileSdkVersion 28

defaultConfig {
    applicationId "com.example.android.tinder"
    minSdkVersion 15
    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'
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
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'
implementation 'com.lorentzos.swipecards:library:1.0.9'
implementation 'com.google.firebase:firebase-core:16.0.6'
implementation 'com.google.firebase:firebase-database:16.0.5'
implementation 'com.google.firebase:firebase-auth:16.1.0'
}
apply plugin: 'com.google.gms.google-services'

我的 build.gradle 代码（项目）

// 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:4.2.0'

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

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

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

我只是希望能够将我的 Firebase 连接到我的 android 应用

解决方案

解决方案是：

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
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'
implementation 'com.android.support:design:28.0.0'

implementation 'com.android.support:support-media-compat:28.0.0' // NEED TO ADD
implementation 'com.android.support:support-v4:28.0.0' //NEED TO ADD

implementation 'com.google.firebase:firebase-storage:16.0.5'
