Unknown module in the .pro file - it is impossible to create an application with the androidextras module enabled

Question

I am working on some Qt / QML application that will be deployed to Android OS. Now I need a module androidextras, but if I put androidextrasinside my file .proas follows

QT += qml quick widgets sql core bluetooth printsupport androidextras

and I rebooted qmake, I get the following error:

Project ERROR: Unknown module in QT: androidextras

I also tried to open and run the Qt Notifier sample project , but the same error occurs, so I can neither create my application, nor an example that should have worked out of the box.

I use KUbuntu 15.04with compiler gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13)and Desktop Qt 5.5.0 GCC 64bitQt. How to create this module androidextras? I have a set Android arm v7that you can see from the screenshot of the Maintenance Tool:

I recompiled all Qt with clear && ./configure -opensource -confirm-license -verbose -cups -plugin-sql-mysql -android-sdk /opt/android-sdk-linux -android-ndk /opt/android-ndk-r10d && make && make install, configured Qt and Qt Kit in QtCreator, changed the build set and the same error appears. Why?
