I am following this question: How to get rss feeds android? And I'm using the code from Mathias Lin.
Notice that in the top, it says:
import org.developerworks.android.FeedParser;
import org.developerworks.android.FeedParserFactory;
import org.developerworks.android.Message;
import org.developerworks.android.ParserType;
import org.xmlpull.v1.XmlSerializer;
I managed to find out how to import an external .jar file (the xmlpull one). Now we have the 4 remaining lines, from org.developerworks.android. I managed to find these 4 files online here: https://www.assembla.com/code/churchmobile/subversion/nodes/FeedParser/trunk/src/org/developerworks/android?rev=25 (I don't know if this is the correct way of doing it).
Now I need my Eclipse project to import these external .java files - how do I do this? Now I have red lines underneath these 4 lines because Eclipse can't find them, obviously.
