无法更新我的 google 播放服务

Question

我正在制作一个使用 firebase 身份验证的项目。我登录 activity 但是当我运行登录时，它说应用程序不会运行直到 Google 播放服务未更新。

以下是我对 app:gradle 文件所做的一些更改。

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

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

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.devanshisukhija.sicsrattendance"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:27.0.2'
    implementation 'com.android.support:mediarouter-v7:27.0.2'
    implementation 'com.android.support:cardview-v7:27.0.2'
    implementation 'com.android.support:design:27.0.2'
    implementation 'com.android.support:recyclerview-v7:27.0.2'
    implementation 'com.android.support:support-v4:27.0.2'
    implementation 'com.google.gms:google-services:3.2.0'
    //implementation 'com.google.android.gms:play-services-base:11.4.2'
    implementation 'com.google.android.gms:play-services:11.8.0'
    implementation 'com.google.firebase:firebase-core:11.8.0'
    implementation 'com.google.firebase:firebase-auth:11.8.0'
    implementation 'com.google.firebase:firebase-database:11.8.0'
    implementation 'com.google.firebase:firebase-auth:11.8.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

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

但我仍然收到以下错误：

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 11.4.2.

Answer 1

删除构建中的行gradle

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

"com.android.application" 包已经有 'com.google.gms.google-services' 个包。

Answer 2

删除此

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

因为你已经提供了

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

所以不需要应用gms.google.services插件。并添加

classpath 'com.google.gms:google-services:3.0.0'

在项目级构建文件中。

希望对您有所帮助。
