问题
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

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:
.

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, i.e. 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:

macx:CONFIG += app_bundle

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.
