convert latitude and longitude to location

When you use the built-in LocationManager and Location of Android to obtain a location, the Location is often null, and the operation is not very convenient, in this Demo, I used the location SDK In the Baidu map API to get the longitude and

This article illustrates the latitude and longitude of Android programming to get a location. Share to everyone for your reference, specific as follows: In the Android application, you can use Locationmanager to get the location information of your mobile device. See the following example: New Android application test

I. preparations: 1. first, convert the obtained longitude and latitude coordinates (generally longitude and latitude) to the degree format. The conversion formula is = left (C3, 3) + mid (C3, find ("°", C3) + 3600)/60 + mid (C3, find ("'", C3) +)/(Note: each parameter depend
