The Earth, on Android

In the previous month I worked on compiling Marble widget to Android. It was a long and hard road but it is here:


(I shot this screenshot on my phone)

The globe can be rotated, and the user can zoom with the usual zooming gesture. Here is a short video example:

The hardest part was to figure out, how to compile everything with cmake instead of qmake and Qt Creator. There are some very basic things what can sabotage your successfully packaged and deployed app. For example if you did not set a version number in cmake for your library...

As you maybe know Marble also uses some elements of QtWebKit, but this is not supported on Android. So I introduced some dummy classes to substitute these (of course, not in their useability) to be able to compile Marble for Android.

You can find here step-by-step instructions, how to compile Marble Maps for Android:

The next steps:
We have decided to separate Marble's functionality into two separate apps. I introduce you Marble Maps and Marble Globe. As their name suggests Marble Map will be essentially a map application with navigation, and Marble Globe will be an app where you can switch to other planets, view historical maps, etc. what also can be used for teaching purposes.

The main goal for the summer to give life for Marble Maps. But if everything goes fine, Marble Globe can be expected too.
