I'm an Android noob and I'm writing an application that has 3 tabs
with buttons added to the tabs dynamically in code. This works fine
with API 11 or up, but not with any lower API. I don't get an error
message with a lower API, the buttons just don't display. However, I
can click/touch just under the tab title and the button will fire
properly. My code is below. Any ideas? Thanks!
