Android : storing large data in android

I am pulling a large amount of json from a restful server. I use the GSON library from google to traverse this json and it works great. Now I want to save all of the json objects in my sqlite db, however I want to make use of a transaction to add all of them at once. This is difficult if you dont have all the objects ready in one datastructe. Since I am traversing the json one object at a time, I guess I would hqve to store that in a data structure such as an arraylist or hashmap and then afterwards use a satabase transaction to do the inserts fast. However... Storing a large amount of data aka 200 000 json objects into a structure in memory can take up a lot of memory and wil probably run out as well. What would be the best way to get all of that json objects into my sqlite db and at the same time not use up a lot of menory in otherwords storing and inserting in a way that allows for a lot of recycling.
