describe a concept, a map overlay: All overlays or overlays to the map, collectively referred to as map overlays. such as callouts, vector graphic elements (including: Polylines and polygons, and circles), positioning icons, and so on.

GPS positioning is now a lot of mobile phones have the function, and very practical. This paper describes the use of GPs positioning in Android in the form of an example. Share for everyone to use for reference. The specific methods are as follows: Generally in

On Android, we can use Qpython to write and execute Python scripts. It on many AndroidThe system functions are conveniently encapsulated, and it is easy to use Qpython to write small programs with simple functions.This example is the underlying script that I used to read the phone's location information and serve as a further process for processing the data.#-*-c
