from service i'm creating a dialog via a dummy activity. Here i'm able to see black background, overall the theme of dialog looks like Android V 2.2. My application minimum API level is 8, if i use holo theme it says i need min api level as 14.

Here is the code i used to create dialog. How to get ICS theme dialog.

  public class PreviewDialog extends Activity{

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // Show the popup dialog
        showDialog(0);


    }



@Override
protected Dialog onCreateDialog(int id)
{
    super.onCreateDialog(id);

    // Build the dialog
    AlertDialog.Builder alert = new AlertDialog.Builder(this);

    alert.setTitle("ALARM REMINDER");
    alert.setMessage("Its time for the alarm ");
    alert.setCancelable(false);

    alert.setPositiveButton("Dismiss", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            GoogleTaskPreviewDialog.this.finish();
        }
    });

    // Create and return the dialog
    AlertDialog dlg = alert.create();

    return dlg;
}
}

MY manifest file entry

 <activity android:name="PreviewDialog" android:theme="@android:style/Theme.Translucent.NoTitleBar"></activity>
