summary

Covers how images are stored as bitmaps (24bpp RGB, 32bpp RGBA, indexed colors), why density buckets matter and when to use mipmap folders, how vectors work (SVG → Android Vector XML), the Canvas/Drawable/View draw path and onDraw, and practical risks: main‑thread loading, OOM from huge bitmaps, need for placeholders and resizing. Recommends libraries: Glide, Picasso and Fresco — Fresco uniquely supports progressive JPEG and special memory handling, with sample Glide usage.
