How can I send back Bundle in Android

I have created Login form and when login success. It will go to MainActivity.java in MainActivity have a button to go to Account Settings with intent sending username and password. Like this:

editu.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
                    Intent i = new Intent(MainActivity.this, EditUser.class);
                    i.putExtra("id",mUser.getId());
                    i.putExtra("username",mUser.getUsername());
                    i.putExtra("pass",mUser.getPassword());
                    startActivity(i);
                    //finish();
        }
    });

And in EditUser.class has the Bundle to get information like:

Bundle args = getIntent().getExtras();

But when I finished managing on account I want to go back to home (MainActivity) by tab on home button<- (picture in link below). It will go out of the Application.

Link is here

And I realized that because of this condition in MainActivity

if (null == args) {
        Toast.makeText(this, getString(R.string.welcome_error_message),
                Toast.LENGTH_SHORT).show();
        finish();
    }

But I don't know, how to send an intent back from EditUser.class to MainActivity.class I have tried the following code, but it didn't work. (Code on EditUser)

public void onBackPressed() {
    Intent i = new Intent(this,MainActivity.class);
    i.putExtra(User.Column.ID,mUser.getId());
    i.putExtra(User.Column.USERNAME,mUser.getUsername());
    i.putExtra(User.Column.PASSWORD,mUser.getPassword());
    startActivity(i);
}

First you need to call the MainActivity using startActivityForResult(intent, requestCode);. Then you do like the following code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == RESULT_OK) {

        // Do something

    }

}

EDIT:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_pedido);

    // You have to enable the home button on action bar doing the following
    getActionBar().setHomeButtonEnabled(true);
    getActionBar().setDisplayHomeAsUpEnabled(true);

}

Then you must also do:

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    if (item.getItemId() == android.R.id.home) {

        finish();

        return true;
    }
    else {
        return MenuActionBar.optionsItemSelected(this, null, item)
                ? true : super.onOptionsItemSelected(item);
    }

}

You have to use onActivityResult() for this. set data to intent and pass it with click of back button click.
