How to find identifiers or names of preloaded system drawings (bitmaps) from a memory dump

I analyze the memory usage in our application and found a strange Drawablesone that constantly "eats" a few megabytes of heap. Here are some screenshots from MAT :

Dominator tree Dominator tree with two fairly large bitmaps

path_to_gc_roots GC root path for one of the above bitmaps

These bitmaps are always displayed in heaps from my phone (Samsung Galaxy Nexus, OS 4.1.1), no matter how long or how intensively I use our application.

MAT - . , , width height , 512x512: bitmap_info

512x512. , "" . ? ?
