Crawling data in Web pages

Here's an example of fetching data from a Web page.

In this example, only the data is obtained from the Web page, but no processing is done, only the data is saved to a TXT file.

This example is written in the Android project.

Package com.example.creepertest;


Import Java.io.BufferedReader;
Import Java.io.BufferedWriter;
Import Java.io.File;
Import Java.io.FileOutputStream;
Import java.io.IOException;
Import Java.io.InputStreamReader;
Import Java.io.OutputStream;
Import Java.io.OutputStreamWriter;
Import java.net.HttpURLConnection;
Import java.net.MalformedURLException;
Import Java.net.URL;
