Android moto 360 gen 1 上的可穿戴 GPS
Android wearable GPS on moto 360 gen 1
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，这是否可能，即使他们说它没有内置 gps 连接？我问的原因是它还说你可以 "track your watches location".. 如果它没有 gps，这怎么可能？它只使用主机设备吗？
- 即使他们说它没有内置 gps 连接，这是否可能？
是的，根据文档，这是可能的 "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.
- 没有gps怎么可能呢？它只使用主机设备吗？
可穿戴设备可以依赖系留连接获取位置数据。
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
注意：
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.
没有内置 GPS 的穿戴设备将依赖配对的手持 GPS 来获取或了解其位置。
希望对您有所帮助！
