txtPassword=(EditText)this.findViewById(R.id.txtPwd);
String uname = txtUserName.getText().toString();
String pass = txtPassword.getText().toString();
if(uname.equals("") || uname == null){
Toast.makeText(getApplicationContext(), "Username Empty", Toast.LENGTH_SHORT).show();
}else if(pass.equals("") || pass == null){
Toast.makeText(getApplicationContext(), "Password Empty", Toast.LENGTH_SHORT).show();
}else{
boolean validLogin = validateLogin(uname, pass, Loginpage.this);
if(validLogin){
