Fused Location Provider是很好的选择吗? [英] Is Fused Location Provider good choice?
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.
- 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?
- 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?
- 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
- 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?
- When GPS is off and I set priority to HIGH, does that mean that the GPS will be automatically turned on, or not?
- Can I set UpdateLocation with Fused provider with HIGH priority on demand to save battery at least a little bit?
- How can I know what Fused provider is using (is it a GPS or a network provider)? And finally
- 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
当GPS关闭并且我将优先级设置为HIGH时，是否表示GPS将自动打开?
When GPS is off and I set priority to HIGH, does that mean that GPS will be automatically turned on, or not?
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
我怎么知道正在使用什么融合服务提供商(是GPS还是网络提供商)
How can I know what Fused provider is using (is it a GPS or a network provider)
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.
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?
Is Fused provider really the best choice for android location? Are there any negative points about it?
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 ?"
