Fused Location Provider是很好的选择吗?

问题描述

我正在开发一个要使用融合位置提供程序的应用程序.但是我有一些疑问，还有几个问题.

I am developing an application where I want to use Fused Location Provider. But I have some doubts, and couple of questions.

1. 当GPS关闭并且我将优先级设置为高"时，这是否意味着GPS将自动打开?
2. 是否可以按需将具有高优先级的Fused提供程序设置为UpdateLocation，以节省至少一点电量?
3. 我怎么知道正在使用什么融合服务提供商(它是GPS还是网络提供商)?最后
4. Fused提供者真的是Android位置的最佳选择吗?是否有任何消极之处?

1. When GPS is off and I set priority to HIGH, does that mean that the GPS will be automatically turned on, or not?
2. Can I set UpdateLocation with Fused provider with HIGH priority on demand to save battery at least a little bit?
3. How can I know what Fused provider is using (is it a GPS or a network provider)?And finally
4. Is Fused provider really the best choice for android location? Are there any negative points about it?

您对此有何看法?预先感谢.

What is your opinion?Thanks in advance.

推荐答案

否，它不会自动打开.但是，如果您使用SettingsApi，则会向用户提示对话框，并提供必须打开GPS的信息.如果用户接受，则GPS将自动激活.检查 SettingsApi

No, it will not be turned on automatically. But if you use SettingsApi, will prompt a dialog to user and gives information that GPS is must be turned on. If user accepts it, the gps will be active automatically. Check the SettingsApi

如果您正确地将融合的提供程序api与SettingsApi一起使用.它将为当前位置请求进行足够的必要设置.

If you use fused provider api with SettingsApi properly. It will make adequate the required settings for current location request.

我认为，在融合提供者之前，您必须直接与提供者(Gps，网络)打交道，但是融合只是问您:您想获得多少准确的位置?"

In my opinion, before fused provider you must deal with directly providers(Gps, network) But fused just asks you, "how accurate locations you wanna receive ?"
