Android - Launching widget manager from market

I'm pretty sure this is a newb question but I can't quite figure it out.

I have a simple application which works as a widget, I use an ImagesWidgetProvider for all widget operations and once installed, it is not displayed as amongst the other applciations and therefore the 'open' button is greyed out once user has downloaded this.

The problem is, some users fail to read the app description that clearly explains how to add a widget to their homescreen which results in 1 star ratings along with 'doesn't work/open' comments开发者_如何学C.

All frustration with users aside, is there something I can do to make the widget selection menu (long press homescreen > widget) pop up when they click 'open' from the market without having to make them have an new app in the app menu?

I'm sure its just something I need to add to the manifest. When installing the app the console states

[2011-08-09 03:40:43 - com.xxx.xxx] No Launcher activity found!
[2011-08-09 03:40:43 - com.xxx.xxx] The launch will only sync the application package on the device!

Is it possible?

No. Best you can do is have a main activity that shows up in the launcher and opens up a help page explaining how to install the widget.
