if statement - else inside if condition not checking in android -

hi in below code else inside if condition inside not checking if username , password matches admin user found directly it's checking if after else if checking.but inside else under if condition not going.

java

else{          querystring = "username=" + username + "&password="                 + password ;         string usertype = databaseutility.executequeryphp("login",querystring);         system.out.print(usertype);          if(usertype.equalsignorecase("admin user found")){              runonuithread(new runnable() {                  public void run(){                      toast.maketext(login.this, "login sucess",                        toast.length_long).show();                            }         });          intent in=new intent(login.this, reports.class);         startactivity(in);      }       else if(usertype.equalsignorecase("no user found")){          runonuithread(new runnable() {               public void run() {                        tv2.settext("invalid username , password");               }          });     }  } 

why not using else instead of else if ???
problem cant java,
debug app , check value of variable usertype different.
if cant debug can show toast check value.

   if (!isinternetpresent) {         showalertdialog(login.this, "no internet connection",                 "you don't have internet connection.", true);          return;       }     //// if condition finishes       string username = usname.gettext().tostring();     string password = pword.gettext().tostring();      // string name = user.get(sessionmanager.key_username);       if (username.equals("")) {         toast.maketext(login.this, "enter username",                 toast.length_long).show();      }     //// if condition finishes       if (password.equals("")) {         toast.maketext(login.this, "enter password",                 toast.length_long).show();      }     //// if condition finishes      else if (!checkusername(username) && !checkpassword(password)){         toast.maketext(login.this, "enter valid username & password",                 toast.length_long).show();     }     //// else if condition finishes      else{         querystring = "username=" + username + "&password="                 + password ;         string usertype = databaseutility.executequeryphp("login",querystring);         system.out.print(usertype);          if(usertype.equalsignorecase("admin user found")){             runonuithread(new runnable() {                 public void run() {                      toast.maketext(login.this, "login sucess",                             toast.length_long).show();                   }             });               intent in=new intent(login.this, reports.class);             startactivity(in);          }         //// if condition finishes            //// suppose else if talking         else if(usertype.equalsignorecase("no user found")){             runonuithread(new runnable() {                 public void run() {                       tv2.settext("invalid username , password");                  }              });         }         //// else if condition finishes      }     //// else condition finishes   

i hope helps.
