Sereja & Pavel,
It should be just a little bit more involved than writing a SQL-based one.
For structured data, you'd need to create your own Cursor subclass, and
return it from the provider's query method. If query results are small
enough to fit in RAM, then it's easiest to use MatrixCursor.
For stream-based data, ContentResolver.openStream seems to eventually
call ContentProvider<subclass>.openFile. This method returns a special
helper class, ParcelFileDescriptor, which allows file descriptors to be
passed across process boundaries.

Expect to override a lot more methods in ContentProvider and
ContentResolver than other people do. You may want to look at the
example WidgetExplorer from "Unlocking Android". Go to the book's
website, download the sample code and look in the code for chapter 5.
I suggest this example because here too, the authors override more
methods than usual because they are making their own ContentProvider.
But of course, the example will not be exactly the same as what you
want.

Hi,
I need to write a ContentProvider to provide a dynamically generated
audio stream to be playable by MediaPlayer. That is MediaPlayer will
use ContentResolver.openInputStream() to play it.
I have read a lot of discussions about this problem but no one had a
solution yet.
The most recent one was in January
2010:http://groups.google.com/group/android-developers/browse_thread/threa...
Have anyone found a solution yet?
Any ideas are greatly appreciated.
Thanks a lot,
--Sergey
