This article introduces the concept of GPS and common classes and methods involved in GPS application development in Android. In this article, a small application is developed to obtain positioning information in real time, including the user's latitude, longitude, height, direction, and moving speed. The Code is as follows: Activity: [java] package comhome. loca

Concepts and basic classes
Recently I learned GPS, so I made a GPS signal parsing tool on the Android system (HTC G7 mobile phone). The following is a summary. Thank you for your correction.

Today, due to work needs, I took out a previously written GPS test program and modified it again. I wrote this program for 11 years. It was not long before I learned Android development. It was an experimental work. Work now needs to be done again. At the same time, I found that I do not know much about the GPS service of And
Today, because of the needs of the work, the previous compilation of a GPS test program has been revised again. This program is a bit of a history, I wrote 11 years, when I learned how to develop Android, is an experimental work. Now the work needs to be put back out to fix. At the same time I found that the Android GPS
Android GPS obtains the coordinates of the current longitude and latitude
In the APP, there may be a need to upload the coordinates of the current location to the server. Today, I provide three ways to obtain the coordinates of the longitude and latitude. The first is implemented through the Android API, the second is
onLocationChanged (Location location){Log. I ("onLocationChanged", "come in ");If (location! = Null){Log. w ("Location", "Current altitude =" + location. getAltitude ());Log. w ("Location", "Current latitude =" + location. getLatitude ());}}
After testing, you can obtain the Location after a period of time (the acquisition time is related to minTime and minDistance ). You must also note that after setting the listener, you cannot use the following method to disable
If you haven't deleted the mobile phone navigation, you will find that you haven't opened anything, but the mobile phone navigation in running services is on! I believe everyone has tried it. When I buy it, everyone only has mobile phone navigation customized.Positioning is not supported. In order to prevent everyone from using Google (Yumin + earning money), China Mobile removed the Google service package (GMS ).Is the most basic and important service package for

I have developed GPS-related embedded software for several years, So when talking about a program to test the GPS positioning module, the first reaction is to read the data from the GPS module through the serial port, and then parse the NMEA format data of GPS.
Today, due to work needs, I took out a previously written
The gps function provided by android allows you to conveniently obtain location information. Because this is the gps used in the simulator again, the gps location information should be sent through ddms.The main. xml file has only one textview node and is not provided. The following permissions are required to operate

Note: Do not forget to add permissions for all of the following operations:
Locationmanager
You can use locationmanager to locate, track, and approaching devices. It does not need to be instantiated directly. We can use context. getsystemservice (context. location_service). To obtain the locationmanager instance.
