Hi, Jean-Baptiste Queru

    Thanks a lot for your nice answers.  You said DownloadProvider only can
be used by system application. Mind you tell me which system application use
DownloadProvider ? If the downloading functionality is really needed in my
app, what should I do ?

    Even though it's bad for me can't use DownloadProvider in my app, but a
very good thing you told me how to use package installer.

Thanks
Ding
