Willem, yes, cross-building for Android can be a real pain. it is very 
difficult to determine what the cause of your build problem is. I assume 
that you are trying to compile using the script in 
packaging/android? Yesterday, I ran into multiple build problems when 
trying to build myself. To be sure that all dependencies are compiled, I 
manually remove the *_arm directories, before running the 
packaging/android/ For the record, I do not use the script. This just downloads NDK/SDK/Qt 
dependencies that I have already have on my system, so I just point the to the already installed NDK/SDK/Qt.

I added a pull request (yesterday) related to Android builds: see But I do not 
see how this can be related to your build issue.
