在moto 360 gen 1上的Android可穿戴GPS [英] Android wearable GPS on moto 360 gen 1
问题描述
我想在moto 360上开发一个应用程序来获取用户当前的gps坐标，即使他们说它没有内置gps连接，这是可能的吗？我问的原因是它也说你可以跟踪你的手表位置..如果它没有GPS，这将是可能的吗？这是否只是使用主机设备？
- 他们说它没有内置GPS连接？
是的，基于文档在Android Wear上检测位置：
穿戴式设备上的位置感知功能可让您创建应用程序，让用户更好地了解其地理位置，移动方式以及周围的情况。
一些可穿戴设备包括一个GPS传感器，可以在没有另一个系绳设备的情况下检索位置数据。但是，当您在可穿戴应用程序中请求位置数据时，您不必担心位置数据的起源位置;系统使用最高效的方法检索位置更新。 您的应用应该能够处理丢失位置数据，以防万一佩戴设备与其配对设备失去连接并且没有内置GPS传感器。
- 如果没有gps ？它是否仅仅为此使用主机设备？
可穿戴设备可能依赖于用于定位数据的连接连接。
如何检查设备上的位置传感器，接收位置数据和监测系留数据连接。
$ b
- 连接到Google Play服务
- 请求位置更新
- 检测车载GPS
- 处理断开连接事件
- 同步数据
注意：不是所有的可穿戴设备都有GPS传感器。如果您的用户外出跑步并将手机留在家中，您的可穿戴应用无法通过连线连接接收位置数据。如果可穿戴设备没有传感器，您应该检测到这种情况并警告用户该位置功能不可用。
依靠连接进行定位的可穿戴设备数据可能会突然丢失连接。如果您的可穿戴应用需要持续的数据流，则必须根据数据中断或不可用的情况处理断开连接。在没有板载GPS传感器的可穿戴设备上，当设备失去连接的数据连接时，会丢失位置数据。
如果您的应用取决于系留数据连接对于位置数据，磨损设备没有GPS传感器，您应该检测到该连接丢失，并警告用户，并优雅地降低您的应用程序的功能。
没有内置GPS的佩戴设备将取决于配对的手持GPS以获知或了解其位置。
希望这帮助！
I would like to develop a app on the moto 360 that gets the users current gps coordinates, is this possible even though they say it doesnt have built in gps connectivity? The reason I ask is it also says you can "track your watches location".. How would this be possible if it doesnt have gps? Does it just use the host device for this?
- Is this possible even though they say it doesnt have built in gps connectivity?
Yes it is possible, based on the document "Detecting Location on Android Wear":
Location awareness on wearable devices enables you to create apps that give users a better understanding of their geographic position, movement and what's around them.
Some wearable devices include a GPS sensor that can retrieve location data without another tethered device. However, when you request location data in a wearable app, you don't have to worry about where the location data originates; the system retrieves the location updates using the most power-efficient method. Your app should be able to handle loss of location data, in case the wear device loses connection with its paired device and does not have a built-in GPS sensor.
- How would this be possible if it doesnt have gps? Does it just use the host device for this?
It is possible for wearable devices to rely on a tethered connection for location data.
How to check for on-device location sensors, receive location data, and monitor tethered data connections.
- Connect to Google Play Services
- Request Location Updates
- Detect On-Board GPS
- Handle Disconnection Events
- Synchronize Data
NOTE:
Not all wearables have a GPS sensor. If your user goes out for a run and leaves their phone at home, your wearable app cannot receive location data through a tethered connection. If the wearable device does not have a sensor, you should detect this situation and warn the user that location functionality is not available.
Wearable devices relying on a tethered connection for location data may lose their connections abruptly. If your wearable app expects a constant stream of data, you must handle the disconnection based upon where that data is interrupted or unavailable. On a wearable device with no onboard GPS sensor, loss of location data occurs when the device loses its tethered data connection.
In cases where your app depends on a tethered data connection for location data and the wear device does not have a GPS sensor, you should detect the loss of that connection, warn the user, and gracefully degrade the functionality of your app.
Wear device without a built-in gps will depend on the paired handheld gps to get or be aware of its location.
Hope this helps!
