i have a html string containing this:

    <!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">
    <html>
      <head>
      <meta http-equiv="content-type" content="text/html; charset=windows-1250">
      <meta name="spanish press" content="spain, spanish newspaper, news,economy,politics,sports">  
      <title></title>
      </head>
      <body id="body">  
<!-- The following code will render a clickable image ad in the page -->
        <script src="http://www.myscript.com/a"></script>
      </body>
    </html>

I need to show that website into a webview in android.

I tryed with all this:

webView.loadDataWithBaseURL(null, txt, "text/html", "UTF-8", null);
webView.loadDataWithBaseURL("x-data://base", txt, "text/html", "UTF-8", null);      
webView.loadDataWithBaseURL("notreal/", txt, "text/htm", "utf-8",null);

Also i tryed removing DOCTYPE tag:

txt=txt.replace("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">", "");

No one of those have work. I just achieved to show the string into the webview (the html code), but not the website that must be created with that html code.

What is wrong?

To load your data in WebView. Call loadData() method of WebView

wv.loadData(yourData, "text/html", "UTF-8");

You can check this example

http://developer.android.com/reference/android/webkit/WebView.html

[Edit 1]

You should add -- \ -- before -- " -- for example --> name=\"spanish press\"

below string worked for me

String webData =  "<!DOCTYPE html><head> <meta http-equiv=\"Content-Type\" " +
"content=\"text/html; charset=utf-8\"> <html><head><meta http-equiv=\"content-type\" content=\"text/html; charset=windows-1250\">"+
 "<meta name=\"spanish press\" content=\"spain, spanish newspaper, news,economy,politics,sports\"><title></title></head><body id=\"body\">"+
"<script src=\"http://www.myscript.com/a\"></script>şlkasşldkasşdksaşdkaşskdşk</body></html>";
