【问题标题】:Android Firebase Connection - Gradle ErrorAndroid Firebase 连接 - Gradle 错误
【发布时间】:2018-06-06 17:16:04
【问题描述】:

我尝试将我的 Android Studio 设置为 Firebase 连接。我按照说明进行操作,这就是我现在所在的位置:

build Gradle Project File

build Gradle Error

Message when i hover other the red underlined implementation

所以我所做的是 -> 添加apply plugin: 'com.google.gms.google-services'compile 'com.google.firebase:firebase-core:16.0.0' 进入模块文件,classpath 'com.google.gms:google-services:4.0.0' 进入项目文件。现在我看到了红色下划线,我该如何解决?

这是来自 build.gradle(模块:App)的代码:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.ozan.firebasetest"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile 'com.google.firebase:firebase-core:16.0.0'
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    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'
}

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

build.gradle(项目:FireBaseTest2):

// 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:3.1.2'
        classpath 'com.google.gms:google-services:4.0.0'


        // 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
}

【问题讨论】:

  • 我想这可能会对你有所帮助stackoverflow.com/questions/50183287/…
  • 请不要链接到代码图像。最好将代码和错误信息复制到问题中,以便阅读和搜索。
  • 我包含了代码。
  • 我是否理解正确...我必须手动将示例包含在错误消息中,并使用与实现 'com.android.support:appcompat-v7:27.1.1' 相同的版本?

【解决方案1】:

我找到了解决方案。只需使用实现更改编译即可!

    【解决方案2】:

    建议您使用基于this link 的最新版(4.0.1) google-services。这有助于避免更多错误。

    build.grandle:

    // 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:3.1.2'
            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()
        }
    }
    
    task clean(type: Delete) {
        delete rootProject.buildDir
    }
    

    还有:

    apply plugin: 'com.android.application'
    
    android {
        compileSdkVersion 27
        defaultConfig {
            applicationId "com.example.ozan.firebasetest"
            minSdkVersion 15
            targetSdkVersion 27
            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 'com.google.firebase:firebase-core:16.0.0'
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.android.support:appcompat-v7:27.1.1'
        implementation 'com.android.support.constraint:constraint-layout:1.1.0'
        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'
    }
    
    apply plugin: 'com.google.gms.google-services'
