java - 尝试添加 Firebase UI 2.3.0 时，我不断收到 gradle 同步错误

Question

问题更新:与教程的创建者交谈后，我尝试使用 Firebase 创建实时聊天。他告诉我在你的 Gradle 中更改编译 'com.google.firebase:firebase-core:9.4.0' 编译“com.google.firebase:firebase-database:9.4.0”

如果是这种情况，我需要在依赖项中更改哪些内容才能使用此 9.4.0 版本？

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

    buildscript {
        repositories {
            jcenter()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:2.3.3'
            classpath 'com.google.gms:google-services:3.1.0'


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

    allprojects {
        repositories {
            jcenter()
            maven { url 'https://maven.fabric.io/public' }  // <= ADD THIS
            maven {
                url "https://maven.google.com"
            }
        }
    }

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


Below is the Module:app Gradle
Here is where I am trying to compile the Firebase UI in order to make a chat application within my app:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.example.aids.a09application"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        aaptOptions.cruncherEnabled = false
        aaptOptions.useNewCruncher = false

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
android {
    useLibrary 'org.apache.http.legacy'
}
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.google.firebase:firebase-core:11.2.0'
    compile 'com.google.firebase:firebase-messaging:11.2.0'
    compile 'com.android.support:appcompat-v7:26.0.1'
    compile 'com.google.android.gms:play-services-maps:11.2.0'
    compile 'com.google.firebase:firebase-auth:11.2.0' // ADDED
    compile 'com.google.android.gms:play-services-auth:11.2.0' // ADDED
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:design:26.0.1'
    compile 'com.android.support:support-v4:26.0.1'
    compile 'com.android.support:recyclerview-v7:26.0.1'
    compile 'com.google.firebase:firebase-database:9.4.0'
    compile 'com.google.firebase:firebase-core:9.4.0'
}
apply plugin: 'com.google.gms.google-services'

这是我现在遇到的错误:

Error:Execution failed for task ':app:processDebugGoogleServices'.
> Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 11.2.0.

Answer 1

要将 Firebase 库版本 11.2.0 与 FirebaseUI 2.3.0 结合使用，您必须按如下方式更新依赖项:

compile 'com.google.firebase:firebase-core:11.2.0'
compile 'com.google.firebase:firebase-messaging:11.2.0'
compile 'com.android.support:appcompat-v7:26.0.1'
compile 'com.google.android.gms:play-services-maps:11.2.0'
compile 'com.google.firebase:firebase-auth:11.2.0' // ADDED
compile 'com.google.android.gms:play-services-auth:11.2.0' // ADDED
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:design:26.0.1'
compile 'com.android.support:support-v4:26.0.1'
compile 'com.android.support:recyclerview-v7:26.0.1'
compile 'com.firebaseui:firebase-ui-auth:2.3.0'

需要添加 firebase-auth 和 play-services-auth，因为使用 11.2.0 构建的 FirebaseUI 版本尚不可用。 FirebaseUI documentation 对此进行了解释。 .

您还应该进行以下更改:

compileSdkVersion 26
buildToolsVersion "26.0.1"

compileSdkVersion 26 的要求位于 Google Play Services Release Notes 中:

When you upgrade your app’s Play services dependencies to 11.2.0 or later, your app’s build.gradle must also be updated to specify a compileSdkVersion of at least 26 (Android O)
