This is critical timing for Qt since it overlaps with the release milestones for Qt 6.7. Moreover, the above references mention multiple topics which can have a large impact on Qt.

The mission for this task is to try Qt on Android 14, and review changes and new features in 14 with the purpose to assess the complexity and related risks of shipping of Qt for Android 14 as promptly as possible.
