Hi,
i found a bug in FragmentManager from original compatibility package, and here https://github.com/JakeWharton/ActionBarSherlock/pull/161/files the patch; but Jake Wharton apply this diff to original compatibility package, not yours nor petedoyle ones.
So, i would to apply these simple 2 rows to FragmentManager in your fork, but sources are incompleted.
I don't find FragmentActivityFeature nor FragmentMapActivity.. so.. for the first i red in your blog, and it's ok... but for the second ?
in petedoyle fork i see that FragmentActivity extends MapActivity and there is some code added.. your FragmentMapActivity has the same code but just extends from MapActivity (and obviously different name) ?
in general, if u can push all your fork source code, it could be better ;D
Tnx,
Massimiliano
