This version number focuses on improvements in performance, stability, and usability, and is a significant improvement over 5.1/5.2.

Major changes in 5.3.0:

    • Qt for Windows Runtime Beta
    • Official support for QNX 6.6 and QNX 6.5 SP1
    • New features introduced

      • Compiled Qt Quick
      • Purchasing API
      • Websockets and Cloud

      • Qt Positioning API supports Android and IOS
      • Qt BlueTooth Support Android
    • Integrated development tools Qt Creator 3.1.1 Announced
    • Plug-ins for VS 2013

I am interested in Qt on Android and have collected improvements for Android:

  • Introduces the new namespace Qtandroid, which contains the following functions:
      • Qandroidjniobject androidactivity (); Ability to get app Activity
      • intandroidsdkversion (); Gets the current device's API level
      • voidstartactivity (const Qandroidjniobject & Intent, int receiverrequestcode, Qandroidactivityresultreceiver * resultreceiver = 0); Start an activity that corresponds to the startactivity or startactivityforresult of the Android activity class. This makes it very convenient to call other apps on Android!
      • voidStartintentsender (const qandroidjniobject & intentsender, int receiverrequestcode, Qandroidactivityresultreceiver * resultreceiver = 0); Startintentsender () or Startintentsenderforresult () for the corresponding Android activity class. The ability to launch new Activity through it or send a Intent to other Android apps to request it to complete a function and return the result.

  • Qaccelerometer implements the Accellerationmode
  • Bug Fixes and improvements:
      • Fixed a crash bug when building sub-items with very many combo boxes and menus
      • Fixed bug where Dir::entrylist () missed the first file while traversing the assets virtual file system
      • Today's defined App launch Welcome screen (splash screen) can be displayed to the first form created
      • Fix a memory leak on the Clipboard
      • The first visit to the assets file system improves performance and speed
      • Fixed font merge issues. This problem causes the loss of some Arabic numerals symbols
I don't think Android is improving much ...

None of the Qtcamera/qtmultimedia I was interested in mentioned. Do not know whether still can not be used in Qt Widgets application, have time to test.
