App Bypassing the Login-screen, even though it shouldn"t

Whenever I launch my App, even from a new emulator with now files created it still executes the bit of code, that says if the file has been created do this intent, I don't understand, it shouldn't, I have no way of testing, because I have an iPhone not an Android phone, in theory the code should not be called, only on the second time loading the app.

Thanks!

Code:

Public class LogIn extends Activity implements OnClickListener {

    Button send;

    EditText user;

    EditText pass;

    CheckBox staySignedIn;

    FileOutputStream Fos;

    String a;

    String b;

    String string = a;

    String string2 = b;

    String DANNYISREALLLLYYYGAAYYYYYIMNOTBS;



    String FILENAME = "userandpass";



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        // TODO Auto-generated method stub

        super.onCreate(savedInstanceState);

        setContentView(R.layout.login);

        send = (Button) findViewById(R.id.bLogIn);

        user = (EditText) findViewById(R.id.eTuser);

        pass = (EditText) findViewById(R.id.eTpassword);

        staySignedIn = (CheckBox) findViewById(R.id.Cbstay);

        send.setOnClickListener(this);

        File file = getBaseContext().getFileStreamPath(FILENAME);

        if (file.exists());

        Intent i = new Intent(LogIn.this, ChatService.class);

        startActivity(i);}      





    public void onClick(View v) {

        // TODO Auto-generated method stub

        switch (v.getId()) {

        case R.id.bLogIn:

            if (pass.length() == 0)

                Toast.makeText(this,

                        "Try to type in your username and password again!",

                        Toast.LENGTH_LONG).show();

            else if (user.length() == 0)

                Toast.makeText(this,

                        "Try to type in your username and password again!",

                        Toast.LENGTH_LONG).show();

             {

                 if (staySignedIn.isChecked()) {



                String a = user.getText().toString();

                String b = pass.getText().toString();

                File f = new File(FILENAME);

                try {

                    Fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);

                    if (Fos != null) {

                    Fos.write(a.getBytes());

                    Fos.write(b.getBytes());

                    }

                    Fos.close();

                } catch (FileNotFoundException e) {

                    // TODO Auto-generated catch block

                    e.printStackTrace();

                } catch (IOException e) {

                    e.printStackTrace();

                }finally  {

                        String u = user.getText().toString();

                        String p = pass.getText().toString();

                        Bundle send = new Bundle();

                        send.putString("key", u);

                        send.putString("key1", p);

                        Intent c = new Intent(LogIn.this, logincheck.class);

                        c.putExtra("key", u);

                        c.putExtra("key1", p);

                        startActivity(c);

                        Toast.makeText(this, "Were signing you in!", Toast.LENGTH_LONG)

                }

                 }
