Thanks for the response Dianne, I still live in the cotton wool word of
University where third parties are friendly types.
Understood, I did some more searching and found another thread in which you
contributed regarding this topic;
http://groups.google.com/group/android-developers/browse_thread/thread/7ee9248deeacd556/b116df9cffe4e045?lnk=gstr#b116df9cffe4e045
In case anyone else is on this trail.
I will also reply to your message there as I need a little
further clarification on the options available for a plugin style
architecture.
Kind regards,
Gavin

Sorry, this is not currently supported.
And you really really wouldn't want to do this, because it would allow any
other app installed on the device to take over your own and use any of its
permissions for malicious purposes under the guise of being you.

Hey!
BACKGROUND
I would like my users to develop their own routines for image
manipulation. Lets presume that a third party has written a class
which implements one of my interfaces;
public abstract class PixelBinaryFilter extends BinaryFilter{
...
protected abstract int generatePixel(int p1, int p2);
...
}
And hence has a class with one method defined, which could multiply
pixel values together, subtract them find their lowest common multiple
basically any routine they can think of.
This class would be complied and then converted to DEX using the dx
tool.
The third party would then download the .dex file to their phones
SDCARD, probably via my application using a 'Get New Routines' request
which takes the URL of the file.
QUESTION
If I have a .dex file on the SDCARD how can I load it at runtime? The
class name and path would be known.
I have been using the Class.forName command for the standard routines
but I don't know how (if) this will work with classes outside of the
application.
Many thanks,
Gavin
