Android application support is coming with Qt 5.1
The upcoming version 5.1 of the Qt graphics widget framework will support Android as a target platform, according to its developers. The Android port of Qt was developed in large part by BogDan Vatra and it has now been pushed into the development branch of the project. In their announcement on the Qt Blog, the developers have posted videos of sample applications working on a range of devices, including the Nexus 4 phone and tablets like the Nexus 7 and Asus Transformer TF300.
Currently, Qt 5 on Android supports traditional Qt widgets and applications written in QML, as well as Qt Quick apps. API access to a number of sensors and some QML media player functionality is also available. Android versions from API Level 10 (Android 2.3.3) and up are supported and applications can be developed in and deployed to devices from version 2.7 of Qt Creator.
Qt 5 for Android is based on the Qt 4 Necessitas port and the developers are calling the community to test the release in the current development branch. They also say, however, that developers should not use this version to develop production applications and should wait until Qt 5.2 is officially released. More information on how to develop and deploy Android apps with Qt 5 is available on the Qt Project wiki.
