Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 6.33 MB, so it installs quickly even on modest connections.
This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

WorldMap is a simple Android app that displays

a map of the world taken from Wikimedia and allows the user to scroll around on
it. The map is licensed as PD-USGOV; PD-USGOV-CIA-WF - more info
here)

The map itself is quite large (6480x3888), so it's way too big to fit in memory
all at once (over 48MB). The VM heap size Android supports is either 16 or 24
megs, so we can't fit the whole thing in memory at once. To overcome this,
WorldApp uses the BitmapRegionDecoder API (available as of Android 2.3.3) to
decode just what it needs to display. The app can also serve as a viewer for
arbitrary images opened via a (3rd-party) file manager.
