Hi in the below code else inside if condition inside is not checking if the username and password matches with Admin user found directly it's checking only if after that else if was checking.But inside else under the if condition was not going.

java

public class Login extends Activity {
    ImageButton login;
    TextView tv1,tv,tv2;
    Button back,home;
    private static final Pattern USERNAME_PATTERN = Pattern
            .compile("[a-zA-Z0-9]{1,250}");
    private static final Pattern PASSWORD_PATTERN = Pattern
            .compile("[a-zA-Z0-9+_.]{4,16}");
    EditText usname,pword,ustype;

    Boolean isInternetPresent = false;
    String username,password;
    HttpPost httppost;
    StringBuffer buffer;
    String queryString;
    String data="";
    int i;
    HttpResponse response;
    HttpClient httpclient;
    CheckBox mCbShowPwd;
    SessionManager session;
     private ProgressDialog progressDialog; 

     ConnectionDetector cd;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.login);
        tv1=(TextView) findViewById(R.id.tv);

        back=(Button) findViewById(R.id.back);
        home=(Button) findViewById(R.id.home);
        tv1.setText("Login");
       // session = new SessionManager(getApplicationContext());
       // session.checkLogin();


       // final HashMap<String, String> user = session.getUserDetails();



        login = (ImageButton)findViewById(R.id.login);  

        usname = (EditText)findViewById(R.id.username);
        pword= (EditText)findViewById(R.id.password);
        ustype= (EditText)findViewById(R.id.usertype);

        tv1 = (TextView)findViewById(R.id.tv2);

        mCbShowPwd = (CheckBox) findViewById(R.id.cbShowPwd);
        cd = new ConnectionDetector(getApplicationContext());
       mCbShowPwd.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                if (!isChecked) {

                    pword.setTransformationMethod(PasswordTransformationMethod.getInstance());
                } else {

                     pword.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
