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
The Global Positioning System (positioning System,gps) is a medium-range circular orbiting satellite navigation system that provides accurate positioning, speed measurement and high precision time standards for the vast majority of the Earth's surface (98%). GPS is widely used in military, logistics, geography, mobile phones, digital cameras, aviation and other fields, has a very powerful function.

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

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.
Common attributes and Metho
LBS (Location Based Services) is based on geographical service, there are at least two layers of meaning, the first to be able to easily obtain the current geographical location, such as latitude and longitude elevation, and the other is based on the current position to provide value-added services, such as to find nearby gas stations, Restaurants, hotels and so on. This is the first step: Get the user's current location, we can use the Android

:
* LocationManager.GPS_PROVIDER:GPS, high precision, but slow and consumption of electricity, and may be due to weather reasons or obstacles to obtain satellite information, the other equipment may not have GPS modules;
* Locationmanager.network_provider: Through the network to obtain positioning information, low precision, less power consumption, access to information faster, do not rely on GPS modules.
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
