Android : Android - random byte arrays taking up memory?

I was investigating my RAM usage when I discovered an array taking up 14 MB. I decided to investigate it.

I used Eclipse's MAT to investigate further into exactly what was happening.

And then further into specifically what was being allocated.

I discovered this large array (although this was not taking up the 14 MB). Does anyone know why there's this array of random characters and digits? In my code, I do not assign an array that is anywhere related to something that could possibly generate this.
