LocationManager每分钟更新，消耗了大量的电池电量 [英] LocationManager updates every minute, consuming a lot of battery power

问题描述

我有一些code类似以下内容：

I've got some code similar to the following:

LocationManager m = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
Criteria c = new Criteria();
c.setAccuracy(Criteria.ACCURACY_COARSE);
String provider = m.getBestProvider(c, true);
Intent i = new Intent(context, LocationReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);

m.requestLocationUpdates(provider, 900000, 0, pi);

下面是接收器清单条目：

Here is the manifest entry for the receiver:

<receiver android:name=".LocationReceiver" />

它的大部分工作正常，并更新每15分钟的时间。但有时，它每分钟更新，并消耗了一堆电池电量。我在做什么错在这里？

Most of the time it works fine, and updates every 15 minutes. Sometimes, however, it updates every minute, and consumes a bunch of battery power. What am I doing wrong here?

编辑：是的LocationManager并不意味着这样使用的后台操作

Is the LocationManager not meant to be used like this for background operations?
