World Map APK for Android Download

WorldMap APK is a straightforward Android application that exhibits a world map sourced from Wikimedia and enables users to explore it by scrolling.

The map’s dimensions are quite extensive (6480,3888), making it too large to be accommodated entirely in memory at once. The total memory required for the map is calculated as (6480 x 3888 x 32 / 8) = 100,776,960, which exceeds 96 megabytes. However, Android’s supported VM heap size is either 16 or 24 megabytes, rendering it impossible to fit the entire map into memory simultaneously.

To address this constraint, WorldMap employs the BitmapRegionDecoder API (accessible since API 10) to decode only the specific portions needed for display.

WorldMap is an open-source application, and its source code can be found here: https://github.com/johnnylambada/WorldMap
