logIn=(ImageButton)findViewById(R.id.logIn_B_logIn);
registr=(ImageButton)findViewById(R.id.logIn_B_registration);
logIn.setOnClickListener(this);
registr.setOnClickListener(this);

}
// else if(passwrd.contentEquals(""))
// {
// Toast.makeText(getApplicationContext(), "Enter password",Toast.LENGTH_LONG).show();
// }
else
{
pd=ProgressDialog.show(LogIn.this, "LogIn", "Logging");
