Mobile platforms
HBD Qt – Day 1
One of the key items we are working on is to create Android and iOS in such a way that they are available for everyone, through the Qt Project. We want to have both Android and iOS platforms fully available to both commercial and open-source users of Qt. We see tremendous value in having these available for the widest possible audience.
Support for both iOS and Android already exists independently, where community driven efforts to run Qt 4.8 on the platforms has been successful. Leveraging these initiatives to provide full support within Qt 5 would be beneficial for the Qt Project. At the moment, the Android port is available from the Necessitas project hosted by
KDE . It is possible to leverage Necessitas for both commercial and open-source Qt users already today. Additionally, we have had initial discussions with the main developer of the Necessitas project and both parties think it would be a good plan to continue development of Qt 5 support within the Qt Project.

For iOS there is a
Qt Labs research project done by Eike Ziller (now part of Digia Qt R&D) to run Qt on iOS. Even though it is more a proof of concept, than a full platform port, it nicely shows what is possible already with Qt 4.8. There also exists a commercial-only Qt 4.8 iOS plugin available from
Mediator Software , which can be leveraged to create Qt 4.8 based applications for iOS. Although
not as complete as the Android port, it can already be used for many kinds of Qt applications. We will continue discussions to see whether it would be possible to leverage it within the Qt Project. We will also need to decide how to tackle the current iOS restrictions that hinder use of Qt Quick.
Our main focus for developing Android and iOS support is on Qt 5. We will start the work on top of Qt 5.0, within the Qt Project, and target having these available for prime time in conjunction with the Qt 5.1 scheduled release for ~ Q2/2013. However, as the currently available Qt 4.8 based Android and iOS projects prove, it is possible to create applications already with 4.8 and 5.0.
