Qt 5.3.1 fails on Android

Esperantisto

I just updated from 5.3 to 5.3.1 and now my UI doesn't show up. When the QML file is loaded I get the following errors on output:

Any ideas?

Same problem here :(

claudiom

The problem comes from using of QML's Screen or using of QScreen in the main.cpp.
Have you used one of the above?

You can use this code:
@
#ifdef Q_OS_ANDROID
QAndroidJniObject qtActivity = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;");
QAndroidJniObject resources = qtActivity.callObjectMethod("getResources", "()Landroid/content/res/Resources;");
QAndroidJniObject displayMetrics = resources.callObjectMethod("getDisplayMetrics", "()Landroid/util/DisplayMetrics;");
QAndroidJniObject configuration = resources.callObjectMethod("getConfiguration", "()Landroid/content/res/Configuration;");

    int screenLayout = configuration.getField<int>("screenLayout");
    int screenLayoutSizeMask = QAndroidJniObject::getStaticField<int>("android.content.res.Configuration", "SCREENLAYOUT_SIZE_MASK");

    int screenLayoutSizeXLarge = QAndroidJniObject::getStaticField<int>("android.content.res.Configuration", "SCREENLAYOUT_SIZE_XLARGE");
    int screenLayoutSizeLarge = QAndroidJniObject::getStaticField<int>("android.content.res.Configuration", "SCREENLAYOUT_SIZE_LARGE");
    int screenLayoutSizeNormal = QAndroidJniObject::getStaticField<int>("android.content.res.Configuration", "SCREENLAYOUT_SIZE_NORMAL");
    int screenLayoutSizeSmall = QAndroidJniObject::getStaticField<int>("android.content.res.Configuration", "SCREENLAYOUT_SIZE_SMALL");

    int screenSize = screenLayout & screenLayoutSizeMask;

    screenSizeStr = "undefined";
    if (screenSize == screenLayoutSizeSmall)
        screenSizeStr = "small";
    else if (screenSize == screenLayoutSizeNormal)
        screenSizeStr = "normal";
    else if (screenSize == screenLayoutSizeLarge)
        screenSizeStr = "large";
    else if (screenSize == screenLayoutSizeXLarge)
        screenSizeStr = "xlarge";

    ddpi = QAndroidJniObject::getStaticField<int>("android.util.DisplayMetrics", "DENSITY_DEFAULT");
    ldpi = QAndroidJniObject::getStaticField<int>("android.util.DisplayMetrics", "DENSITY_LOW");
    mdpi = QAndroidJniObject::getStaticField<int>("android.util.DisplayMetrics", "DENSITY_MEDIUM");
    hdpi = QAndroidJniObject::getStaticField<int>("android.util.DisplayMetrics", "DENSITY_HIGH");
    xhdpi = QAndroidJniObject::getStaticField<int>("android.util.DisplayMetrics", "DENSITY_XHIGH");
    x_xhdpi = QAndroidJniObject::getStaticField<int>("android.util.DisplayMetrics", "DENSITY_400");
    xxhdpi = QAndroidJniObject::getStaticField<int>("android.util.DisplayMetrics", "DENSITY_XXHIGH");
    xxxhdpi = QAndroidJniObject::getStaticField<int>("android.util.DisplayMetrics", "DENSITY_XXXHIGH");

    densityDpi = displayMetrics.getField<int>("densityDpi");
    dp = 1.0f * densityDpi / mdpi;

    screenType = "ddpi";
    if (densityDpi == ldpi)
        screenType = "ldpi";
    else if (densityDpi == mdpi)
        screenType = "mdpi";
    else if (densityDpi == hdpi)
        screenType = "hdpi";
    else if (densityDpi == xhdpi)
        screenType = "xhdpi";
    else if (densityDpi == x_xhdpi)
        screenType = "x_xhdpi";
    else if (densityDpi == xxhdpi)
        screenType = "xxhdpi";
    else if (densityDpi == xxxhdpi)
        screenType = "xxxhdpi";
#else

maybe this can be a good workaround ;-)

Before trying workarounds, I suggest checking out Qt 5.4 alpha version, or Qt 5.3.2 snapshot - a lot of issues have been fixed there (for example, screen orientation bug introduced in 5.3.1).
