Answer 1

您需要注意以下几点：

运行Android 2.3（Gingerbread）或更新版本以及Google Play服务10.0.1或更高版本的设备
来自Google Repository的Google Play服务SDK，可在Android SDK Manager中找到
最新版本的Android Studio 1.5或更高版本
在Android Studio中，将FCM依赖项添加到您的应用级build.gradle文件中。

摇篮：

dependencies {
       compile 'com.google.firebase:firebase-messaging:10.0.1'
    }

将以下内容添加到您应用的清单中：

<service
    android:name=".MyFirebaseMessagingService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>
<service
    android:name=".MyFirebaseInstanceIDService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>
