「無法解析：com.google.firebase：火力核心：9.0.0」

Question

我想用火基地，在我的Android應用程序，以驗證

1. 我創建的應用程序，然後下載的JSON文件並將其粘貼到app文件夾

2. 我將此添加到我的build.gradle>項目

   // 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:2.2.1' 
        classpath 'com.google.gms:google-services:3.0.0' 
        // 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 
   } 
   

3. 添加此應用到我的build.gradle>應用程序

   apply plugin: 'com.android.application' 
   android { 
       compileSdkVersion 24 
       buildToolsVersion "23.0.1" 
       defaultConfig { 
        applicationId "com.example.mahmoud.loginwithfirebase" 
        minSdkVersion 15 
        targetSdkVersion 24 
        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-v7:24.2.1' 
       testCompile 'junit:junit:4.12' 
   } 
   apply plugin: 'com.google.gms.google-services' 
   

   但此錯誤出現

此MainActivity.java

package com.example.mahmoud.loginwithfirebase; 

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

    public class MainActivity extends AppCompatActivity { 

     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_main); 
     } 
    } 

Answer 1

添加此行com.google.firebase:firebase-auth:9.6.1'到你的build.gradle依賴項裏ke這裏：https://firebase.google.com/docs/android/setup，而不是核心使用auth。
