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.
:
* 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.
Android gets the current location through gps
GPS Positioning includes GPS Positioning and base station positioning: GPS positioning is based on satellite positioning, requires the head to be empty, the positioning error is 2-10 m
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:

Modifying only the activity file is not enough. Because the Android system is secure and the service is authorized, You need to modify the manifest. xml file.
Many friends may have questions, that is, the debugging problem of GPS
Welcome to add ArcGIS API for Android QQ Exchange Group: 337469080First talk about the reasons for writing this article, in the process of discussion in the group, someone mentioned the problem of positioning, just, I have done related work when the relevant things, so summed up, to share out, because I level limited, the bug is unavoidable, but also hope that a higher high man criticized. Nonsense not much to say, directly into the subject.To locate
Positioning GPS positioning and base station positioning: GPS positioning is based on satellite positioning, the need to open the head, positioning error in 2-10 meters, the base station network positioning is based on distance from the mobile phone positioning, the error is large, as long as the mobile phone has a signal can be located; Getting GPS information i
Recently, GPS is being used on Android. It is always difficult to get up or down, no data, and debugging is in progress. Therefore, we carefully analyzed the code from top to bottom. The soul function is
The requestlocationupdates function is mainly used to start a monitor and listen for location change information.
Not much nonsense. Start analysis.

First, the location city is based on the Map service API.GPS positioning the city requires two steps:1, to obtain the user's current location of longitude, latitude.2. Convert to city name according to latitude and longitude.You can only use map services when you convert to city name by latitude. I can't do it by myself.There are two Map service APIs, one is Baidu map, the other is Google map. Baidu Map API
