我是firebase的新手,我想实施Firebase云消息传递(FCM)我正面临着开始使用它的问题. firebase没有初始化.谢谢你的帮助.

的build.gradle

// 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:2.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

build.gradle(app)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        applicationId "com.example.sai_praneeth7777.hasportal"
        minSdkVersion 21
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs',include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:24.0.0'

    compile 'com.google.firebase:firebase-crash:9.2.0'
    compile 'com.google.firebase:firebase-messaging:9.2.0'

    compile 'com.mcxiaoke.volley:library:1.0.18'
    compile 'com.google.code.gson:gson:2.4'

    compile 'com.android.support:cardview-v7:24.0.0'
}

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