Android的 - 是否有已轮询GPS定位可查询的服务？ [英] Android - Are there query-able services that already poll for GPS location?

问题描述

我为检查您的位置大约每5分钟或更少的应用程序的一些想法。也许每1分钟，我还没有确定。很显然，我可以简单地创建，检查手机的GPS定位，是每个N分钟的服务。但是，这是对电池的潜在流失。

I have some ideas for an app that checks your location about every 5 minutes or less. Maybe every 1 minute, I'm not sure yet. Obviously I can simply create a service that checks what the phone's GPS location is every N minutes. But that is a potential drain on the battery.

我想知道，是否有已经在Android操作系统，已经为手机GPS定位查询运行的任何内部服务？这样，或许我可以简单地问这些服务的位置而不是使GPS位置请求自己是什么，为了节省电池用量。

What I was wondering, are there any internal services that are already running in the Android OS that are already polling for the phones GPS location? That way perhaps I can simply ask those services for what the location is instead of making the GPS location request myself, in order to save on battery usage.

推荐答案

没有这样的系统服务存在。您可以创建一个服务，并定期检查<一href=\"http://developer.android.com/reference/android/location/LocationManager.html#getLastKnownLocation%28java.lang.String%29\"相对=nofollow> lastKnownLocation（） 。

No such system services exist. You can create a service and periodically check for lastKnownLocation().

设计一个位置感知应用程序依赖于很多因素。试着回答这个问题：

Designing a location-aware app depends on a lot of factors. Try answering this questions:

1. 请你总是需要GPS定位或基于位置不够好网络？


2. 如何保鲜确实位置需？


3. 请你需要的位置，即使用户不移动？


4. 请你需要的位置，即使手机处于睡眠模式？
