I've been trying to get my ads to display in this type of layout.
Tabs -> LinearLayout -> ListView -> header. The header is set via addHeaderView and is displaying normally. If I were to move the ads anywhere else they display normally (so its not a setup issue). Using ads in the header of a listview works fine in my other projects.
So this seems to be a very specific problem, the ads simply refuse to display when placed in the header of a listview inside a tabhost.
My logs show no activity from admob at all. There is either a bug here or limitation of the sdk. Does anyone have any experience or insight into this issue?
EDIT
I found the solution. It actually had to do with padding that was in the root of my Tabview. For more checkout my answer here
