public class signinactivity extends Activity {
	EditText edname,edpwd;
	Button b;
	LoginDataBaseAdapter logindatabaseadapter;
	protected void onCreate(Bundle savedInstanceState) 
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.login);
		logindatabaseadapter=new LoginDataBaseAdapter(this);
		logindatabaseadapter=logindatabaseadapter.open();
		edname=(EditText) findViewById(R.id.editTextUserNameToLogin);
		edpwd=(EditText) findViewById(R.id.editTextPasswordToLogin);
		b=(Button) findViewById(R.id.buttonSignIn);
		b.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				String userName=edname.getText().toString();
				String password=edpwd.getText().toString();
				String storedpassword=logindatabaseadapter.getSinlgeEntry(userName);
				if(password.equals(storedpassword))
				{
					Toast.makeText(signinactivity.this, "Logged in Successfully", Toast.LENGTH_LONG).show();
