我在哪里使用注册位置更新时遇到问题
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME_MS, 1, mSingleShotGpsListener);
我可以看到联系人DB被更新了，根据我的愿望，Z似乎需要一段时间，然后是大量的GC操作(见下面的日志(。由于我在触发位置检查后很快就显示了一些动画，因此这是次优性能。知道为什么会发生这种事/我能做些什么来阻止它吗？
我在Nexus S上进行了测试，在日志中没有看到这种行为/性能问题/联系检查。
谢谢你的帮助！

注册更新会导致GPS出现并报告位置。很可能在该设备上注册了一个被动定位接收器，原因是在获取更新时，由于您导致GPS位置被提取和报告，正在对联系人数据库进行一些操作。
考虑到你在Nexus设备上看不到这种行为，它不是Android的一部分。因此，这是制造商对该设备或该设备上安装的其他应用程序进行的一些定制。
你可以通过"adb shell dumpsys location"查看哪些应用程序注册了被动位置更新。
