How to use aggregated data
Question 2: The main function of aggregated data: mobile phone aggregation: The mobile phone aggregated data platform is the first original data service platform specially designed for the development of smart phones in China. Provide tens of millions of professional data calling services including LBS, information, public relations, transportation and daily life. Website aggregation: the website aggregation platform provides free data query for website users; Data call; Data update service. JS one-click call, steadily increase website traffic. LBS aggregation: LBS location service platform provides all kinds of location-based query and call services for free. Users can query LBS location information through the platform, and developers can call API for free. LBS(Location Based Service) location query service is widely used in business, medical care, industry and personal life. 1. Location query service for ordinary users. 2. Open API services provided by developers. Users can query related information according to IP address, latitude and longitude, address and mobile phone base station information on the LBS homepage of aggregated data.
Question 3: Who can use aggregated data? Teach me how to find personal data. I can use some tools to summarize the data directly and then analyze it, such as this one. . .
Question 4: How to use aggregated data in android studio? First, register the api to be used in the application (strictly speaking, data is obtained through the api). At first, I thought I had to verify my ID card, but I didn't know it was necessary until I tried it, so I won't describe the steps in detail. I chose the weather forecast under the weather forecast (there is also a national weather 20 15.07.03). After the successful application, there is an operation menu in my file, and there is an "interface" below.
Question 5: How to use Android to develop an aggregated data Api in a project is very simple. After registration, it depends on which API you want to click to apply for data, and then you can get APPkey. .
Question 6: Functional classification of aggregated data Aggregated data is a comprehensive cloud data platform, which provides original data API services for smartphone developers, webmasters, mobile device developers and graphic manufacturers. Including mobile phone aggregation, website aggregation and LBS aggregation. Aggregated data provides free base station data for developers, mobile Unicom base stations and telecom base stations, covering more than 1000 major cities at home and abroad, such as public transport information data, food, clothing, housing, transportation, finance, LBS data and other valid and legal information data. API calls are flexible and convenient, and support developers to customize data services.
Functional classification:
Mobile phone aggregation
Mobile phone aggregation data platform is the first original data service platform in China, which is specially provided for the development of smart phones. Provide tens of millions of professional data calling services including LBS, information, public relations, transportation and daily life.
Website aggregation
The website aggregation platform provides free data query for website users; Data call; Data update service. JS one-click call, steadily increase website traffic.
LBS polymerization
LBS location service platform provides various location-based query and call services for free. Users can query LBS location information through the platform, and developers can call API for free.
LBS(Location Based Service) location query service is widely used in business, medical care, industry and personal life (1). (2) Open API service provided by developers. Users can query related information according to IP address, latitude and longitude, address and mobile phone base station information on the LBS homepage of aggregated data.

Question 7: How to use the aggregate data Api for Android development in the project? You should know about network requests and json parsing.
Question 8: How do I aggregate the values in a dataset using an aggregation transformation? It's not convertible.
Question: How does the nba interface aggregate data analysis data? Java parsing JSON steps.
The 1. server converts the data into json strings.
First, the server-side project needs to import the jar package of json and the jar package that json depends on into the builtPath path.
Then the data is converted into a json string, and the core function is:
Public static string createJsonString (string key, object value)
{
JSON object JSON object = new JSON object()；
jsonObject.put(key，value)；
Returns JSONObject. tostring ();
}
2. The client converts json strings into corresponding javaBean.
The client gets the json string (because the jar package of json has been integrated into the android project, there is no need to import it here).
Public class HttpUtil
{
Public static string getJsonContent (string urlStr)
{
attempt
{get HttpURLConnection connection object.
URL url = new URL (urlstr);
HttpURLConnection = (HttpURLConnection) url
. open connection()；
Set connection properties
conn . setconnecttimeout(3000)；
conn . setdoinput(true)；
conn . setrequestmethod(GET)；
Get the corresponding code.
int resp code = conn . getresponsecode()；
if (respCode == 200)
{
Returns convertstream2json (conn.getinputstream ());
}
}
catch(malformedurexception e)
{
TODO automatically generated catch block
e . printstacktrace()；
}
IOException e
{
TODO automatically generated catch block
e . printstacktrace()；
}
Return;
}
Private static string convertstream2json (InputStream InputStream)
{
string JSON str =；
ByteArrayOutputStream is equivalent to the memory output stream.
ByteArrayOutputStream out = new ByteArrayOutputStream()；
Byte[] buffer = new byte [1024];
int len = 0；
Move the input stream to the memory output stream
attempt
{
while((len = inputstream . read(buffer，0，buffer.length))！ = - 1)
{
out.write(buffer，0，len)；
}
Converts a memory stream to a string.
JSON str = new String(out . tobytearray())；
}
catch(io exception......& gt& gt
Question 10: Android. How to parse JSON data of aggregated data? There are many open source components of json parsing in java java.
Gson Google, with good performance, uses more Android clients.
Jackson claimed to be the best.
Fastjson Alibaba is open source and claims to have better performance than Jackson.
Just find a component, read the official documents, practice a few demo, and you will soon get started.
