I extracted some urls by jsoup.
and made a download manager.
and it seems parcelfiledescriptor doesn't work.
i tryed regist broadcaster but did't work.
I don't know where should I insert "parcelfiledescriptor" and "regist broadcaster"
i have no idea to fix this...
ps. these urls goes like this
is there any methods to open this url without Excel viewer? "http://docs.google.com/gview?embedded=true&url= url" does'nt work
