Recently in doing an Android project, need to use GPS to obtain location information, check from the API, found that access to location information only need a very simple sentence can: Copy Code code as follows: Getlastknownlocation (Locationmanager.gps_provider), So happy. But in the code, the return value (Location type) is always null. It's so depressing. Check on the internet for

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.#-*-coding:utf-8-*-ImportAndroidhelperImport Time fromMathImportradiansdroid=Androidhelper.

First you need to know the GPS coordinate system. The GPS coordinate system follows the WGS-84 standard, under which the GPS chip can emit different packet formats. The GPS data can be classified into Gpgga, Gpgsa, GPGSV, GPRMC and so on, according to the different frame-frame head of the data. These frame headers iden
