Well, I'm needing to save potentially over 1000 values in about 12 or so arrays. I was kind of hoping that there was an easy way to save an array and then load it back without having to do a bunch of stuff to it. I'm not too experienced with programming so most of my knowledge comes from reverse engineering examples I see, and I haven't been able to find an example on saving a populated array and re-loading it later.
What would be the best way to go about saving the data, since shared preferences can't save a String[] type or an int[] type. If I mush them all together into one item I don't know how to separate them later.
