I successfully adding a jpg file into ContentResolver by using insert,
and I can query contentResolver to get information about the jpg file.
But if I go to Pictures app, the new picture is not showing. I
debugged into the code and found out that in the Camera source code,
when it tries to generate bitmap for this new file, the
BitmapFactory.decodeFileDescriptor(fd, null, options) sets the
options.outwidth and outheight to -1. If I restart the emulator, the
value will be correct 800 X 600. So, what do I need to do to make sure
that after I generate a new file (.jpg) in SDCard and it will be shown
in Pictures right away. I thought about using rescan of content
provider, but because I might need to generate more than one jpg files
at the same time, if they all call rescan, it might be a mess. Any
suggestions?
