About this app
WorldMap is a simple Android app that displays a map of the world taken from Wikimedia (http://upload.wikimedia.org/wikipedia/commons/3/33/Physical_Political_World_Map.jpg), and allows the user to scroll around on it.
The map itself is quite large (6480,3888), so it's way too big to fit in memory all at once (6480 x 3888 x 32 / 8) = 100,776,960 -- over 96 megs. The VM heap size Android supports is eith 16 or 24 megs, so we can't fit the whole thing in memory at once.
So WorldMap uses the BitmapRegionDecoder API (available as of API 10) to decode just what it needs to display.
WorldMap is open source, and the source code is here: https://github.com/johnnylambada/WorldMap

Decent, a map and nothing more. The countries and continents are sized to their proper dimensions however. Africa far outstrips Greenland for example. But aside from major cities and political boundaries, don't expect anything else from this app.

I like the graphics,its clear. A bit more improvement on the zooming in would be better because when zoomed in closer, some names are blurry and hard to read. šš»

I'm not a phone or computer person but I do like to look at the world map I like how easy it is to use I like to be able to pull up the roads and I like to be able to see the buildings the roads it's been very helpful even in the area which I live some of the functions I can't use very well but that's because I'm not a phone or computer savvy person other than that I think it's a good app
