android - Android 蓝牙设备定位器

Question

如何定位使用我的应用程序的其他蓝牙设备并在地图上显示它们，包括范围、确切位置，如雷达地图。

Answer 1

Possible design idea :

You want to implement this with the help of a webservice.

Make your app report its being used(may be you want to report at regular intervals and shutdown of app) along with location information (probably you want to use GPS, have a look at this : Obtaining User Location).

Make you radar app to read those information and prepare the map.

Cons :

1. Availability of GPS will affect your application
2. Accuracy is limited.

Answer 2

您可能这样做的唯一方法是，如果您的蓝牙从设备能够单独跟踪和报告其位置（例如 GPS）。

否则根本不可能。Android 设备中的蓝牙无线电和天线将没有测向功能。
