添加Firebase

Question

当我将firebase库添加到android studio时，我收到错误：

我已成功下载google-service.json文件并正确放置，添加库时出现错误

// Top-level build file where you can add configuration options common to allsub-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()
    }
}

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

这是我的应用级依赖

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.example.omarr.fireapp"
        minSdkVersion 21
        targetSdkVersion 26
        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 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.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compie 'com.google.firebase:firebase-database:11.6.0'
    compile 'com.google.firebase:firebase-crash:11.6.0'
    compile 'com.google.firebase:firebase-auth:11.6.0'
    testCompile 'junit:junit:4.12'

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

请帮帮我 还请建议我应该熟悉的主题，以便将来能够自己处理这些错误。 感谢

Answer 1

compie 'com.google.firebase:firebase-database:11.6.0'

中有拼写错误

必须编译而不是 compie 。正确的陈述是：

    compile 'com.google.firebase:firebase-database:11.6.0'

Answer 2

有一个拼写错误：

使用：

compile 'com.google.firebase:firebase-database:11.6.0'

而不是：

compie 'com.google.firebase:firebase-database:11.6.0'

同时添加google maven repo：

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}
