我遇到问题我在哪里使用
注册位置更新 mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME_MS, 1, mSingleShotGpsListener);
我可以看到联系人数据库已更新，我希望Z似乎需要一段时间，然后加载一系列GC操作（参见下面的日志）。由于我在触发位置检查后很快显示一些动画，因此结果是次优性能。知道为什么会发生这样的事情/我能做些什么来阻止它？
我已经在Nexus S上测试过，并且在日志中看不到此行为/性能问题/联系人检查。
感谢您的帮助！

注册更新会导致GPS出现并报告位置。很可能在该设备上有一个被动位置接收器由于某种原因而被注册，因为您获取更新是因为您导致获取GPS位置并且报告正在对联系人数据库进行某些操作。
鉴于你在Nexus设备上没有看到这种行为，它不是Android的一部分。因此，制造商已对设备或该设备上安装的其他应用程序进行了一些自定义。
您可以使用“adb shell dumpsys location”查看为被动位置更新注册的应用。
