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.

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 meters, the Base Station Network Positioning i

I was developing androidProgramWhen calling GPS, they all use functions directly. Public void Requestlocationupdates (Long mintime, float mindistance, Criteria, pendingintent intent) However, the customer recently said that the GPS of the mobile phone is not accurate enough, so he learned about the two parameters in the function signature from the Google developer website.

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

As we all know, we need to simulate GPS on the simulator when we develop, we can always null in the location, check the Internet, and find the following solutions: Online Warrior's Solution: When acquiring GPS information on the simulator, the location loc = locationmanager.getlastknownlocation ("GPs") is used to obtain location information, but often in debuggi

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

GetBestProvider (criteria, false ); TxtCrerita. setText ("best provider:" + bestProviders ); } }); Www.2cto.com Conclusion (see GPS again ): From the above knowledge, we can know that we need to use the LocationManager System Service to use the GPS service on the Android platform. We can use the Context. getSystemServi

: * 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.
