Well, I'd at least consider adding MATCH_DEFAULT_ONLY on the queryIntentActivities() call, if you are building a launcher-type app. Beyond that, I'm not sure if by default you get everything in the GET_ series of flags -- if so, that might be the source of your woe, and expressly listing the GET_ flags you really need might help.

Yeah, I don't know how you would do "page at a time" type stuff here. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 3.7 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
