Thanks for that idea - yeah not exactly what I want but its another alternative.
URL "about:blank" brings up the browser with "about:blank" in the input window Scheme "http" with no URL brings up Google web search page with http: in the input window. Both of them look a little weird... I don't think my idea of a query for "http" type and CATEGORY_LAUNCHER will work either because the broswer launch intent filter does not have http as a type. So maybe there is no good way to do it. Is there anything else to try?
