爲什麼連接到火力讓我的應用程序在Android工作室

Question

的build.gradle的問題（應用程序）：

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' 
    compile 'com.android.support:design:24.2.1' 
    compile 'com.android.support:support-v4:24.2.1' 
    compile 'com.google.android.gms:play-services:7.5.0' 
    compile 'com.google.firebase:firebase-core:9.8.0' 

    testCompile 'junit:junit:4.12' 
} 

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

build.grade（項目）：

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.2.0' 
     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 
    } 
} 

谷歌谷歌服務及庫是所有這些都是最新的SDK。

我收到以下錯誤：

Error:(42, 1) A problem occurred evaluating project ':app'. 
> Failed to apply plugin [id 'com.google.gms.google-services'] 
    > Version: 7.5.0 is lower than the minimum version (9.0.0) required for google-services plugin. 

我想從我的應用程序連接到火力地堡和我有google-services.json文件app文件夾內。
