private class parser extends asynctask<void, void, void> {     string h;     string url1 = "http://www.klt.net.pl/";     string url2 = "http://www.klt.net.pl/index.php?a=logowanie";     string url3 = "http://www.klt.net.pl/index.php?a=przedmecz1&b=2&d=2038";      @override     protected void onpreexecute() {         super.onpreexecute();         pd = new progressdialog(mainactivity.this);         pd.settitle("parser");         pd.setmessage("loading...");         pd.setindeterminate(false);         pd.show();     }      @override     protected void doinbackground(void... params) {         try {             connection.response response = jsoup.connect(url1)             .method(connection.method.get)             .timeout(50000)             .followredirects(true)             .execute();         document document = jsoup.connect(url2)             .cookies(response.cookies())             .get();          } catch (ioexception e) {             e.printstacktrace();         }         return null;     }      @override     protected void onpostexecute(void result) {         pd.dismiss();     } } 

edit:

@override protected void doinbackground(void... params) {     try {         connection.response response = jsoup.connect(url1)         .method(connection.method.get)         .timeout(50000)         .followredirects(true)         .execute();          connection.response loginres = jsoup.connect(url2)         .useragent("mozilla/5.0 (macintosh; intel mac os x 10_10_5) applewebkit/537.36 (khtml, gecko) chrome/44.0.2403.157 safari/537.36")         .data("login", getlog2,         "haslo", getpass2)         .cookies(response.cookies())          .method(method.post)         .execute();          map<string, string> cookies = new map<string, string>();         cookies.addall(loginres.cookies());          connection.response otherres = jsoup.connect(url3)         .cookies(cookies)         .method(method.post)         .execute();          d3 = jsoup.connect(url3)         .cookies(otherres.cookies())         .get(); 

my updated code. ok? have error in map (cannot instatiate type , cannot resolved type).

to login need know data post (id, password, session cookie , etc...), , url address need post to.

this information contained in login form, i'll explain steps required below:

step 1: id , password need enter login should inputs of form. right-click area type in id , select inspect element (assuming on chrome). there able inspect property of inputs , form.

step 2: closely investigate form , keep record of all input fields (including hidden fields). need know name , value of fields. need know if form request made in get or post , action value form.

step 3: let's fun part. use following code snippet make request server , retrieve desired content.

connection.response loginres = jsoup.connect(loginurl)                                .useragent("mozilla/5.0 (macintosh; intel mac os x 10_10_5) applewebkit/537.36 (khtml, gecko) chrome/44.0.2403.157 safari/537.36"                                .data("login", yourid                                      "haslo", yourpassword)                                .cookies(response.cookies()) //this same cookie used url2!                                .method(method.post)                                .execute(); 

• loginurl request address, in case "http://www.klt.net.pl/index.php?a=logowanie".
• useragent tells server browser details.
• data put name&value pairs of input fields in form.
• cookies put cookies, need check if request requires cookies accepted server, can checked in network tab under "cookies" section. in case, same cookie used url2.
• method specifies request method.

the retrieved loginres object contain info need, html, cookies , everything.

after you've logged in, make sure store cookie value in map object below:

map<string, string> cookies; cookies.putall(loginres.cookies()); 

and make sure pass cookies cookies parameter in future requests, below:

connection.response otherres = jsoup.connect(otherurl).cookies(cookies).... 

this ensure login session maintained , server knows authenticated user.

----------------update------------

declare map cookie beginning of doinbackground task. store all cookies after make every request. so:

cookies = response.cookies(); cookies.putall(loginres.cookies(); cookies.putall(otherres.cookies();
