[PyQt] pyqtdeploy, Android and extensions

[Robert Kent]

Hi Phil,

So, I've gone back and used python-for-android (i.e. kivy) to build 
numpy and I still get the same error, so it seems that its either the 
way python is built or the way in which it imports modules that is 
different. I'm still confused by the fact that exception message is that 
it doesn't know how to import a module built as a C extension... this 
makes me think that I have to do something with python rather than numpy...

Any thoughts any one?

Cheers, Rob

The prescribed technique works up to a point, i.e. placing the shared object (.so) file next to the executable (in Android's case the generated lib<APP_NAME>.so). However, when the app tries to import the module I get the following:
