---EDIT

This is source code i'm working now, based on http://www.coderzheaven.com/2011/07/17/how-to-read-webpage-contents-as-a-string-in-android/

    package tm.tresura;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public class HttpUtils {

  public static String getContents(String url) {
        String contents ="";

  try {
        URLConnection conn = new URL(url).openConnection();

        InputStream in = conn.getInputStream();
        contents = convertStreamToString(in);
   } catch (MalformedURLException e) {
        Log.v("MALFORMED URL EXCEPTION");
   } catch (IOException e) {
        Log.e(e.getMessage(), e);
   }

  return contents;
}

private static String convertStreamToString(InputStream is) throws UnsupportedEncodingException {

      BufferedReader reader = new BufferedReader(new    
                              InputStreamReader(is, "UTF-8"));
        StringBuilder sb = new StringBuilder();
         String line = null;
         try {
                while ((line = reader.readLine()) != null) {
                        sb.append(line + "n");
                }
           } catch (IOException e) {
                e.printStackTrace();
           } finally {
                try {
                        is.close();
                } catch (IOException e) {
                        e.printStackTrace();
                }
            }
        return sb.toString();
  }
}

and errors:

Error:(76, 16) error: no suitable method found for v(String)
method Log.v(String,String,Throwable) is not applicable
(actual and formal argument lists differ in length)
method Log.v(String,String) is not applicable
(actual and formal argument lists differ in length)

Error:(78, 16) error: no suitable method found for e(String,IOException)
method Log.e(String,String,Throwable) is not applicable
(actual and formal argument lists differ in length)
method Log.e(String,String) is not applicable
(actual argument IOException cannot be converted to String by method invocation conversion)

Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.

and what are those errors? and your missing class? and your code? we can't help you if you don't show anything. Take a look how to ask: http://stackoverflow.com/help/how-to-ask and http://stackoverflow.com/help/mcve — Mariano Zorrilla, Sep 23 '15 at 12:25
Log.v() accepts 2 or 3 paramenters, check the method documentation first before posting question — Vladyslav Matviienko, Sep 23 '15 at 12:42

Log.v("MALFORMED URL EXCEPTION");

afaik v() has different signature, this method takes two params - tag and some body, try to add additional String param

Log.v("TAG","MALFORMED URL EXCEPTION");

Thanks for help, maybe it was obvious for you, but not for me, I have big lack of knowledge. Now compiler works fine, but app "unexpectedly exit". I'm, working at this.
