Qt performance issues

  • Hi,

    I have a Qt app developed on Android and the problem is that is using too much graphic memory.

    Can you help me with some qml optimization or how can be implemented a mechanism for cleaning the memory?

    Well i cannot help you with more details about QML as i too new to QML. I too have developed an android app with the traditional Qt C++ based programming but saw a performance drop in Qt 5.1. Later i switched to QML and developed a small part of that app(uses lots of animations with transformations ) and saw a huge performance difference. QML uses scene graph based on OpenGL ES 2.0 or OpenGL 2.0 for its rendering.
    So just try to create a small QML app as per your c++ application.
    Start from here
    "QML Application Developer Resources":http://qt-project.org/doc/qt-5.1/qtdoc/qtquick-applicationdevelopers.html.
    QML is quite easy to adopt :)
