Module "QtQuick" is not installed (Android porting)

shedo

Hi all,
I'm trying to porting my application to android with qt5.4 but I have this error:

W/Qt (30916): qrc:/qml/FrontEnd.qml:1 ((null)): qrc:/qml/FrontEnd.qml:1:1: module "QtQuick" is not installed

This is my .pro

@TEMPLATE = app
TARGET = sandbox-build-android

QT+= qml quick widgets printsupport xml svg

INCLUDEPATH += [...]# my include path

Input

HEADERS += [...] # my include
SOURCES += [...] # my source

RESOURCES += ../sandbox/resources.qrc

contains(ANDROID_TARGET_ARCH,armeabi-v7a) {
ANDROID_EXTRA_LIBS = [..]
}

Default rules for deployment.

include(deployment.pri)@

This is my deployment.pri:

@android-no-sdk {
target.path = /data/user/qt
export(target.path)
INSTALLS += target
} else:android {
x86 {
target.path = /libs/x86
} else: armeabi-v7a {
target.path = /libs/armeabi-v7a
} else {
target.path = /libs/armeabi
}
export(target.path)
INSTALLS += target
} else:unix {
isEmpty(target.path) {
qnx {
target.path = /tmp/$${TARGET}/bin
} else {
target.path = /opt/$${TARGET}/bin
}
export(target.path)
}
INSTALLS += target
}

export(INSTALLS)@

In my FrontEnd.qml I have this import:
@
import QtQuick 2.4
import QtQuick.Controls 1.3@

I don't see any substantial difference from .pro of example projects that work properly on Android.

Hi and welcome to devnet,

What are the small differences ? Which example did you use as a base ?

shedo

I have taken a new Android project (Android Templates, Qt Quick Application) as base.

@TEMPLATE = app

QT += qml quick widgets

SOURCES += main.cpp

RESOURCES += qml.qrc

Additional import path used to resolve QML modules in Qt Creator's code model

QML_IMPORT_PATH =

include(deployment.pri)@

it was very minimal so I saw another example "Calendar" and I noticed that I was missing this flag " OTHER_FILES " so I added all the paths of my QML files to it but the problem persists.

I also retrieved the apk from my smartphone and I have extracted the contents. I noticed that my apk didn't include some libraries that are present in the apk sample that works:

bq. libqml_Qt_labs_folderlistmodel_libqmlfolderlistmodelplugin.so
libqml_Qt_labs_settings_libqmlsettingsplugin.so
libqml_QtQml_Models.2_libmodelsplugin.so

OTHER_FILES doesn't influence on deployment

One thing that looks fishy is your ANDROID_EXTRA_LIBS line. You call it with = which clears its current content and replace by what follows

Not sure if this applies to your issue, but I experienced something similar when deploying on Android (Qt 5.3.1). I got "module "QtQuick" is not installed" sporadically when deploying project with bundled Qt libraries in APK.

The issue stopped when I started signing the package before deploying.
