Starting activity which is already running

Starting activity which is already running

I want to delete one button of an activity but when I start it like:
Intent inte = new Intent(PasswordConfirmationActivity.this,
IndexActivity.class); UserAuthentication UA = new UserAuthentication();
control = UA.UserControl(EdtText.getText().toString());
inte.putExtra("confirmation", control); startActivity(inte); finish();
It gives me error.
The activity is also running when another activity is running.
And that is the code which I delete the buton:
Boolean loginControl = getIntent().getBooleanExtra("confirmation",false);
if (loginControl == true) {
ViewGroup layout = (ViewGroup) ButtonClick2.getParent();
if(null!=layout)
layout.removeView(ButtonClick2);
}
this is the loccat :
