跟踪超过100个并发geofences新的Andr​​oid API [英] Tracking more than 100 simultaneous geofences with the new Android API

问题描述

我在9000平方公里的区域利益3500左右的地理点，我想我的应用程序在后台运行，并通知用户，只要他或她是在接近上述任何点。

I have around 3500 geographical points of interest in an area of 9000 km^2, and I want my app to run in the background and notify the user whenever he or she is in proximity to any of the aforementioned points.

新地理栅栏API 在谷歌我介绍/ O 2013似乎是完美的这项工作，特别是它的电池寿命优化，但我似乎无法注册超过100 geofences之前，我的状态code <一个href="https://developer.android.com/reference/com/google/android/gms/location/LocationStatus$c$cs.html#GEOFENCE_TOO_MANY_GEOFENCES"相对=nofollow> GEOFENCE_TOO_MANY_GEOFENCES （使用演示应用程序的修改版本）。

The new Geofence API introduced during Google I/O 2013 seemed perfect for the job, especially as its optimized for battery life, but I can't seem to register more than 100 geofences before I get the status code GEOFENCE_TOO_MANY_GEOFENCES (using a modified version of the demo app).

是否有可能增加此限制？也许通过一些设置或API？

Is it possible to increase this limit? Perhaps through some setting or API?

推荐答案

我建议你下载所有指向设备上的sqlite的分贝。然后找到最接近99点是这样的：<一href="http://stackoverflow.com/questions/3695224/android-sqlite-getting-nearest-locations-with-latitude-and-longitude">Android - SQLite的获取最近的位置（经纬度）并注册那些点与Android监控

I'd recommend downloading all points to a sqlite db on the device. Then find the closest 99 points with something like this: Android - SQlite Getting nearest locations (with latitude and longitude) and register those points with Android to monitor.

然后设置一个显著改变地理围栏，你可以用它来监控，如果用户的位置发生了变化，以至于当他们退出地理围栏，你应该重新加载感兴趣的最近点。

Then set a "significant change" geofence that you can use to monitor if the user's location has changed enough that when they exit this geofence, you should reload the closest points of interest.
