QtQuick Error on Android(3009 (EGL_BAD_MATCH))



  • I can not run well on Android A QML.

    I got the error.

    E / libEGL (8495) eglMakeCurrent: 534 error 3009 (EGL_BAD_MATCH)

    The example works fine when run on windows.

    This missing LIB?

    Does anyone have any idea?

    Hi,

    I'm not a specialist in that area but just looking at the log it seems that you have a shader that fails to compile.

    If it's one of yours, are you sure that its compatible with EGLSL ?



  • He compiled yes, this is the application log in AndroidOS
    Well it works on windows7.



  • The error occurs when you run:

    void MainWindow::on_pushButton_clicked()
    {

    QQuickView *view = new QQuickView;
    qDebug()<<"flavio";
    view->setSource(QUrl("qrc:/qml/pathview/pathview-example.qml"));
    view->show();
    

    }


  • Lifetime Qt Champion

    Are you using the OpenGL or ANGLE build on windows ?



  • No, I'm testing the examples of Qtquick in android.

    I took an example QtQuick then created a project with QMainWindow and include the pushbutton to run QtQuick



  • If you can follow the link:

    https://groups.google.com/forum/?fromgroups=#!topic/android-qt/GTZsO5tbTso

    There is project untitled2.7z.



  • @Flavlo:
    Have you found any solution for this yet? I am getting a similar error.
    Refer , http://qt-project.org/forums/viewthread/31522/



  • No, but I'm following the waiting list for the bug fix.



  • Today I will check again. when I find the solution,'ll warn you.



  • Hi guys..
    I am gettin the same error.
    Flavio do let me know when the bug is fixed :)

    Regards,
    Mansi



  • Hi!

    I am getting the same error, too.

    I just created a new project (qt quick 2 - build in elements), changed nothing and tried to run it on the android simulator.

    Any help is very welcome.

    Regards,
    Oliver.



  • I had a large project running successfully on Android with Qt5.1.0
    Then I "ported" the QML Quick 1.0 and declarative to QtQuick2.1 and quick.
    Now I get the error as described above.



  • Same issue here: porting a desktop application from Qt 4 to Qt 5.2 for Android. After struggling for some hours, I've found the problem is related to multiple top levels.
    My code worked perfectly on Nexus 7 (libEGL_tegra) but miserably crashed on Samsung devices (libEGL_mali). I don't know yet why this difference, but I've temporarily fixed it by removing the creation of the main window and by focusing on a single QQuickView. My next experiments will involve QWidget::createWindowContainer(), because I still need to use a QWidget.
    The code you've posted seems to share the same design, so I'd suggest to try a different approach. :)



  • ok, it's a long time but I don't know if you sorted it or not.

    First, your shader compiling on windows doesn't mean it will compile onandroid. Just an exemple:
    In windows you aren't required to set the precision of floating points and vectors, it may give you a warning but keep running anyway. But when you try the same code on Android, some mobiles requires you to set the float precision.
    And this is the most common case, got this problem, and sorted it by setting precision at every float.

    Second, I've got one implementation problem with QGLShaderProgram, using QOpenGLShaderProgram instead sorted my problem. I don't know exactly why but seems that QGLShaderProgram include some code in your shader that may crash in some GLSL drivers.

    In your link I couldn't find the shader code you are running, mind to tell me where is it, so I can take a look?

    Regards and sorry for my bad english.



  • Anybody try issue in Qt 5.3?
