How can I speed up my RSS feed Android App?
none of those Variables need to be set to "" inside the for loop, they have already been set.



This can be set early and outside of the if block and the for loop:

 dbimg = "http://s14.postimg.org/cs10sq11d/whitemega.png";


Otherwise it is a Magic string that you will have to search for later.



The id isn't doing anything here, I don't think that you need it at all, you should be able to call the code like this

handler.insertrssfeedData(dbtitle, dbDesc, dbimg, dbimgicon, dblink, dbpubdate, dbfff, dbsourcename , dbimagecheck);


otherwise you are creating this variable and assigning a lot of data to it and never using it every time you go through the loop.
