A simple Android example app that displays a very large world map bitmap and lets users scroll around it. It demonstrates using BitmapRegionDecoder to decode only the visible portion of a bitmap too large to fit in memory.
Use cases
- display a huge image on android without running out of memory
- learn how to use bitmapregiondecoder
- implement a scrollable background image in an android app
- pan around a large map on mobile
- android example for decoding partial bitmaps
When to choose
- you need a reference implementation for scrolling large bitmaps on Android
- you want to learn BitmapRegionDecoder usage in Java
When to avoid
- you need a full-featured map application with zoom and tiles
- you need a maintained library with a license and active development
