问题1

致电apply plugin properly

问题2

添加play-services:10.2.1

试试这个方法

 apply plugin: 'com.android.application'
 apply plugin: 'com.google.gms.google-services'
 android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"

    defaultConfig {
        applicationId "aminfocraft.harsh.firebasenotificationdemo"
        minSdkVersion 15
        multiDexEnabled true
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.google.android.gms:play-services:10.2.1'
    compile 'com.google.firebase:firebase-messaging:10.2.1'
}

【解决方案2】：

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

应该在依赖项之外

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:25.3.1'    
    compile 'com.google.firebase:firebase-messaging:10.2.1'
    }

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

【解决方案3】：

这个：

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

应该在dependencies之外

 dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:25.3.1'    
    compile 'com.google.firebase:firebase-messaging:10.2.1'
    }

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

另外你忘了添加播放服务依赖..

添加compile 'com.google.android.gms:play-services:10.2.1'
