对同一提供商使用多个 LocationManager requestLocationUpdates(...)
我的应用程序后台运行了一个位置服务，其中 requestLocationUpdates(LocationManager.GPS_PROVIDER, 5*60*1000 , 1, this) 每 5 分钟获取一次位置更新。在一项给定的活动中，我需要更频繁的更新。我可以创建另一个 LocationManager 并在此活动中为同一提供程序注册另一个 requestLocationUpdates 侦听器，如下所示？
locManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 1, this);
我已经尝试过了，它似乎有效，但我想确保它不会与后台服务产生任何冲突......
I've got a location service running in background of my app with requestLocationUpdates(LocationManager.GPS_PROVIDER, 5*60*1000 , 1, this) to get a location update every 5 min. In one given activity I need much more frequent updates. Can I create another LocationManager and register another requestLocationUpdates listener for the same provider in this activity as shown below?
locManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 1, this);
I've tried and it seems to work, but I'd like to be sure that it won't create any conflict with the background service...

别担心。在后台，只有一个 GPS 位置提供程序实例以您设置的两次频率的最小值运行。
值得关注的一点是您设置的 100 毫秒间隔。我认为 1 秒更新是大多数 GPS 芯片组可以设置的最小间隔。
Don't worry about it. Under the hood there is only one GPS location provider instance running with a frequency of minimum of those two time that you have set.
A point of concern is the 100ms interval that you have set. I think that 1 sec updates is the least interval that you can set for most GPS chipsets.
