向任意设备发送消息
Firebase Cloud Messaging (FCM) provides a reliable and battery-efficient connection between your server and devices that allows you to deliver and receive messages and notifications on iOS, Android, and the web at no cost.

高级消息定位功能
Easily target messages using predefined segments or create your own, using demographics and behavior. Target messages to devices that have subscribed to specific topics, or get as granular as a single device.

自定义通知内容
Deliver notification messages immediately, or at a future time in the user's local time zone. Send custom data, and set priorities, sounds, and expiration dates, and track custom conversion events.

无需编写代码即可发送通知
Notification messages are fully integrated with Google Analytics for Firebase, giving you access to detailed engagement and conversion tracking. Monitor effectiveness from a single dashboard with no coding required.

A/B 测试通知
Use A/B testing to try out different versions of your notification messages, and then easily see which one performs best against your goals. A/B testing can also be used with Remote Config.
A/B testing was built in partnership with Google Optimize, an A/B testing and personalization tool for the web.
