How to launch an Activity without a UI?
<p>Is it in any way possible to launch an activity from the main function without having a UI? i.e. is there a way to create a sort of "wrapper" around another activity, i.e. by launching the main activity, it takes you to another activity automatically.  </p>

<p>If that is not possible, is there a way to remove the main activity from the stack so that clicking the back button does not take you to a blank UI?
Here's an example of what I'm trying to do:</p>

<pre><code>public class WrapperActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:555-1212"));
        startActivity(intent);
    }
}
</code></pre>
