For dex, we currently store only method sizes and "other entries". These are computed by apkanalyzer, and don't map directly to the dex-layout sections:

Since "data" is large and easily broken down, we should split up into:
* string_data_item
* class_data_item
* code_items
* other data

I'm hoping this information will be useful to see the effects of build changes (e.g. proguard changes, multidex vs single dex)
