Question

问题更新：在与教程的创建者交谈后，我正在尝试使用Firebase创建实时聊天。他告诉我改变你的Gradle编译com.google.firebase：firebase-core：9.4.0＆＃39; 编译com.google.firebase：firebase-database：9.4.0＆＃39;

如果是这种情况，为了使用这个9.4.0版本，我需要在依赖项中进行哪些更改？

       // 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'

这是我现在得到的错误：

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

由于您使用的是com.android.support:customtabs:26.0.1，因此您必须添加repositories“https://maven.google.com”端点。
自25.4.0以来的所有支持库都在google maven repo中作为described here。

在你的情况下，像;

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

此外，如果您想添加最新的 Firebase库v.11.2.0 ，您必须添加与described here相同的回购。

Answer 2

要在FirebaseUI 2.3.0中使用版本11.2.0的Firebase库，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，因为尚未提供使用11.2.0构建的FirebaseUI版本。这在FirebaseUI documentation。

中有解释

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：

将应用的Play服务依赖项升级到11.2.0或之后，您的应用程序的build.gradle也必须更新以指定 compileSdkVersion至少为26（Android O）

Answer 3

如果尚未安装，则必须转至SDK Manager并下载API 26（Android 8.0）的SDK平台文件。然后将所有支持库文件更新到版本26.0.1，例如编译'com.android.support:design:25.3.1'以编译'com.android.support:design:26.0.1'等等。您还需要将compileSdkVersion 25更改为26，将buildToolsVersion“25.0.2”更改为“26.0.1”，将targetSdkVersion 25更改为26.并将maven“https://maven.google.com”添加到存储库

Firebase正在寻找版本26.0.1的支持库。由于没有安装或者你的buildToolsVersion和compileSdkVersion没有指向它，gradle无法解决它们。

尝试添加Firebase UI 2.3.0时，我一直收到gradle同步错误
