Streaming pull parser is the way. I recommend GSON, as this has small memory footpring (just pull parsing is about 16K , jackson is way bigger)

and this is slow, and gives you memory meltdown.

In case you need java objects out of your JSON data , you may try my small databinding library building on GSON (shameles self advertising off):
