Just in case anyone else encounters the same problem, and for what it is 
worth, here is how I was able to use a text layer with click-able 
markers on an a Open Street Map map rendered on Android:

1) start with the mobile-navigation.html example
2) remove the TouchNavigation control from the controls array
3) add the touch.js file from

     http://anders.com/cms/352/OpenLayers/iPhone/Android/Touch.Gestures

to the html page
4) add this line after the map is initialized

  window.touchhandler = new TouchHandler(map, 1);

The constant in the last line is a hack. The author suggests using a 
value of 4. It seems that 1 works better for me. I could be wrong. 
Caveat emptor.
