[Interest] One question about Qt and one not...

[Igor Mironchik]

Hi. Forget my second question. I've found the solution. It's forgotten

But my first question is still actual. And even can I mix Qt libraries  
built with android-5 platform with another library built, say, with  
android-19 platform in one Qt-based Android application?
