this code:
public void getauthorization(string password, string user) { string responsestring="empty response api"; string userpassword = user+":"+password; try { httpclient httpclient = new defaulthttpclient(); httpget httpget = new httpget(_url); httpget.setheader("authorization", "basic "+base64.encode(userpassword.getbytes(),base64.no_wrap)); httpresponse httpresponse = httpclient.execute(httpget); statusline statusline = httpresponse.getstatusline(); if(statusline.getstatuscode() == httpstatus.sc_ok){ bytearrayoutputstream out = new bytearrayoutputstream(); httpresponse.getentity().writeto(out); out.close(); responsestring = out.tostring(); } else{ //closes connection. httpresponse.getentity().getcontent().close(); throw new ioexception(statusline.getreasonphrase()); } }catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } } can me?
since android 3.0 cannot use network connection on main thread. better create asyntask doinbackground execute httpget.
