>I am working on a mobility GPS plugin. For this I am playing around
loading libraries. I created the library with the same Necessitas QT
creator that I use in the testing example. So I create this library libIMPInterface.so. This has the following pro:

>QT += sql
>TARGET = $$qtLibraryTarget(Interface)
>TEMPLATE = lib
>SOURCES += \ 
>    ../../interfaces.cpp
>HEADERS += ../../interfaces.h
>INCLUDEPATH += ../../ 
>DESTDIR = /sdcard/Android/data/org.ilri.GPSTest

System.load("/sdcard/Android/data/org.ilri.GPSTest/libInterface.so");
//This is fix... I am just testing loading my GPS library!
