Choose File Dialog

Question

Does anyone know of a complete choose file dialog  Maybe one where you can filter out all files except for ones with specific extensions    I have not found anything lightweight enough to implement easily into one of my projects  The only other option seems to be using OI FileManager s open intents  but that requires the user already having the file manager installed    I would be grateful if someone could point out a Dialog that would allow the user to browse folders and select a file  and return the path
