I have a custom file which has an extention of *.tax which managed by my application which I am developing currently.I could associate .tax files any where on the sdcard in android device but when the same  *.tax  i tried to open from an email as attachment when downloaded, but it says no proper application found to open this file.
Is there any separate attributes which i need to set in manifies.xml file in order to associate my *.tax file to open from Email or is there any permissions or things which i missed. plz help me out.
