@detlev - thank you.. you reply really helped
i was finally able to delete an album
i just made the following changes to the code:
StringBuffer xmlBuffer = new StringBuffer();
xmlBuffer.append("<entry>");
xmlBuffer.append("<link rel='edit'"
+"href='http://picasaweb.google.com/data/entry/api/user/
androidproject007/albumid/"+albumid+"'/>");
xmlBuffer.append("</entry>");
String s = "http://picasaweb.google.com/data/entry/api/user/
androidproject007/albumid/"+albumid;
URL url = new URL(s);
now it works!!!
i have to use the underlying protocol here because i am developing for
android which does not allow the direct use of the picasa web albums
api
