“未安装模块“ QtQuick””（Android移植）

Question

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

LIBS += -L$$PWD/../../edalab/else-datamodel-classes/build-buildAndroid-Android_for_armeabi_v7a_GCC_4_9_Qt_5_4_0-Debug/ -lbuildAndroid

INCLUDEPATH += [...]
DEPENDPATH += [...]

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 project that work properly on Android.

UPDATE

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:

libqml_Qt_labs_folderlistmodel_libqmlfolderlistmodelplugin.so libqml_Qt_labs_settings_libqmlsettingsplugin.so libqml_QtQml_Models.2_libmodelsplugin.so libqml_QtQml_StateMachine_libqtqmlstatemachine.so libqml_QtQuick.2_libqtquick2plugin.so libqml_QtQuick_Controls_libqtquickcontrolsplugin.so libqml_QtQuick_Controls_Styles_Android_libqtquickcontrolsandroidstyleplugin.so libqml_QtQuick_Dialogs_libdialogplugin.so libqml_QtQuick_Dialogs_Private_libdialogsprivateplugin.so libqml_QtQuick_Layouts_libqquicklayoutsplugin.so libqml_QtQuick_Window.2_libwindowplugin.so

Here is an example .pro file. I've scrapped out of too specific stuff. The directory structure is as follows:

.
├── Project
│   ├── app.pro
|   ├── android
|   │   ├── res
|   |   │   ├── drawable-hdpi
|   |   |   └── ...

│   │   └── ...
|   ├── icons

Differently from you I do not have a src dir and the QML files are moved to a content directory. I've also a resource file for the same QML files, ie Qml.qrc . Translation files (aka .ts files) are contained in the main dir with sources. The compiled translations (aka .qm ) files are instead in the subdirectory translations .

The directory android and ios contain files specific to the platforms, in particular we have the res directory useful to provide an icon and a wallpaper to the app for the android platform. The same android dir is used as APK package source (see .pro below). The ios directory contains the property list .

The lib directory contains a sub-dir for each platform with the recompiled library for that environment.

Here is the corresponding project file:

TEMPLATE = app
macx:CONFIG += app_bundle

# QT IMPORT
QT += gui qml quick [...]

#include subproject
include(SubProject/subproject.pri)
# Default rules for deployment
include(deployment.pri)
# Compilation flags [specific to the different OSs]
include(flags.pri)

TARGET = "appName"  # just needed for me since I change target between "App" and "AppPRO"

INCLUDEPATH += [...]

    $$PWD/include/sub2 

!isEmpty(QMAKE_LFLAGS_RPATH):LIBS += \

    Qml.qrc

    ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android          # contains the dir structure of the APK, actually it contains just res

}

This is the manifest . Qt Creator allows editing via a UI interface or the textual editing. To add a manifest (Qt Creator 3.3), as stated in the comments, just go to Projects > Build > Build Android APK > Create Templates .
