WorldMap is a simple yet useful Android app that displays a detailed map of the world in high resolution. The map is sourced from Wikimedia and is quite large, making it impossible to fit in memory all at once. However, the app uses the BitmapRegionDecoder API to decode only what is needed to display the map, making it fast and efficient.

The app is easy to navigate and allows users to scroll around the map easily. It is perfect for anyone who needs to view a detailed map of the world on their Android device. WorldMap is also open source, and its source code is available on GitHub for anyone who wants to contribute to its development.

Overall, WorldMap is a great educational and reference app that provides a detailed view of the world map on Android devices. It is highly recommended for anyone who needs a high-resolution map of the world on their device.
