需要考虑的事情:

不要太频繁地要求更新GPS，这会消耗电池电量。我目前 使用30分钟作为默认的应用程序。 增加“到最后已知位置的最小距离”检查。没有这个，你的分数 当GPS无法使用，位置被三角定位时，会“跳来跳去”吗 从发射塔传来的。或者您可以检查新位置是否在精度范围之外 最后一个已知位置的值。

Skyhook (http://www.skyhookwireless.com/)提供的位置提供程序比谷歌提供的标准程序快得多。也许这就是你要找的。我和他们没有关系。

需要考虑的事情:

不要太频繁地要求更新GPS，这会消耗电池电量。我目前 使用30分钟作为默认的应用程序。 增加“到最后已知位置的最小距离”检查。没有这个，你的分数 当GPS无法使用，位置被三角定位时，会“跳来跳去”吗 从发射塔传来的。或者您可以检查新位置是否在精度范围之外 最后一个已知位置的值。

目前我正在使用，因为这是可靠的获取位置和计算距离为我的应用程序......我正在用它来申请出租车。

使用谷歌开发人员开发的融合API，融合GPS传感器，磁力计，加速度计，还使用Wifi或细胞定位来计算或估计位置。它还能够准确地提供建筑物内部的位置更新。 详情请访问链接 https://developers.google.com/android/reference/com/google/android/gms/location/FusedLocationProviderApi

要为你的应用程序选择正确的位置提供者，你可以使用Criteria对象:

Criteria myCriteria = new Criteria();
myCriteria.setAccuracy(Criteria.ACCURACY_HIGH);
myCriteria.setPowerRequirement(Criteria.POWER_LOW);
// let Android select the right location provider for you
String myProvider = locationManager.getBestProvider(myCriteria, true); 

// finally require updates at -at least- the desired rate
long minTimeMillis = 600000; // 600,000 milliseconds make 10 minutes
locationManager.requestLocationUpdates(myProvider,minTimeMillis,0,locationListener); 

阅读requestLocationUpdates的文档，了解如何考虑参数的更多细节:

通知的频率可以使用minTime和 minDistance参数。如果minTime大于0，则LocationManager . properties将自动返回 可能会在位置更新之间休息minTime毫秒 为了节约能源。如果minDistance大于0，一个位置只会 如果设备按minDistance米移动，则广播。获得 尽可能频繁地通知，将两个参数都设置为0。

更多的想法

You can monitor the accuracy of the Location objects with Location.getAccuracy(), which returns the estimated accuracy of the position in meters. the Criteria.ACCURACY_HIGH criterion should give you errors below 100m, which is not as good as GPS can be, but matches your needs. You also need to monitor the status of your location provider, and switch to another provider if it gets unavailable or disabled by the user. The passive provider may also be a good match for this kind of application: the idea is to use location updates whenever they are requested by another app and broadcast systemwide.
