android - 像地理围栏一样使用 geofire

Question

我想制作一个应用程序，当用户进入某个区域时发送通知。我知道存在 Geofire，我想使用，因为我使用的是 Firebase 数据库，但我从未使用过它，而且我不知道它是否具有与 Google Geofences 相同的行为。

谁能告诉我能否用 Geofire 实现我的想法？

非常感谢您的回答!

如本文中的官方 Firebase 博客所示，GeoFire Goes Mobile

What is GeoFire?

If you're new to GeoFire, it's a geolocation library that maps string keys to locations and stores them in Firebase. Using GeoFire, you can answer a simple but important question: Which keys lie within a given geographic region? But GeoFire's features don't stop at simple location queries, it's true power is that everything happens in realtime. When objects move, events will be fired as they enter, exit and move around the region.

GeoFire opens a wide range of possibilities: You can build an app that displays who's going for a run within a mile radius of yourself and show their location in realtime. You can display taxis within a search radius and animate them as they move. Or you can build an app that simply lists all interesting bars nearby.

回答您的问题，是的，可以使用 Geofire 实现您的想法，甚至更多。
