gains. If I have time, I would like to share with you the second method, which is much easier than this, in fact, you can fully refer to the Code http://blog.csdn.net/octobershiner/article/details/6639040 in the previous article You only need to set two sensor. You can change type_accelerometer to sensor. type_orientatio, but the methods we share today are the best. This should be the future android standard. The sensor should be introduced here for the time being. Let's take a look at t

normal. HTTP request methods include GET, POST, PUT, PATCH, and DELETE. REST can also use these request methods. The REST Webservice usually responds to an XML file, but unlike SOAP, REST does not necessarily need to respond to the returned XML file. It can also be in CSV or Json format. Many companies adopt REST-style WebServices, such as Google Glass API, Twitter, Yahoo, Flickr, and Amazon. For example, Google has a Webservice, Google Maps API, which provides two output formats: JSON and XML.

It took two days to use Google's API to make such a small thing. In fact, there are not many real implementation codes, just a dozen lines. A time-consuming task is to understand the functions of each API and debug JavaScript. The following is a brief introduction of several functions I have used this time. • Constructor google. search. LocalSearch () This actually creates a LocalSearch Service, which is the same as other services (News, Blog, Web) and used by SearchControl. These services deter

application to select an appropriate location provider by setting attributes in the LocationProvider. Geocoder: class used to process geocode and reverse geocode. Geocoding refers to converting an address or other description into a longitude or latitude. Reverse geocoding refers to converting a longitude or latitude to an address or a description language, which contains two constructors, the coordinates

longitude,Location to get the address, positioning can get latitude and longitude, labeled on the map, but the purpose is to output the address,Then both of these involve a common problem, one is to transfer latitude and longitude to the address, one is based on the address of the latitude and longitude, then these two are a reverse process, we see how to implement this process, in the map development, this is what we call geocoding and anti-coding.Now we're talking about the German SDK, so the

The same is the floating widget, look at the search widget, click to see its default configuration is to use ESRI's GeoCode service to perform the search, as shown in If we have other geocode services or have our own need to retrieve service layers, such as Mapservice, Featureservice, can be conf

Java calls the Google Map API to resolve the address, the resolution of latitude and longitude instancesUse the Reverse address resolution feature of Google Maps, provide a latitude and longitude to get the corresponding address, or give a fuzzy address, get latitude and longitude, in the Java Background code processing, this is using Google's GeoCode service. In general, there is no limit to the use of small amounts of data. According to Google's off

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 calls need to register Baidu account, and apply for App_key, Google Maps API directly cal

Quick query of geographic locationThe Geocoder component provides a quick, geographically-based query that can be queried to display the geographic location of a map by entering an address by adding a query input box. Using Geocoder to move the map display to the specified location area is faster than panning and blooming maps. This feature requires the use of the locator service (location services).Prerequisites:* Adobe Flash Builder 4.5.1 and later* Used ArcGIS API for Flex is 3.2 and later1 n
