"module “QtQuick” is not installed"（Android 移植）
"module “QtQuick” is not installed" (Android porting)
我正在尝试使用 qt5.4 将我的应用程序移植到 android，但出现此错误：
W/Qt (30916): qrc:/qml/FrontEnd.qml:1 ((null)): qrc:/qml/FrontEnd.qml:1:1:模块 "QtQuick" 未安装
这是我的.pro
TEMPLATE = app

include(deployment.pri)
这是我的 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 {

qnx {
target.path = /tmp/$${TARGET}/bin
} else {
target.path = /opt/$${TARGET}/bin
}
export(target.path)
}
INSTALLS += target
}
export(INSTALLS)
在我的 FrontEnd.qml 中，我有这个导入：
import QtQuick 2.4
import QtQuick.Controls 1.3
我没有看到与在 Android 上正常工作的示例项目的 .pro 有任何实质性区别。
更新
我看到另一个例子“Calendar”，我注意到我缺少这个标志“OTHER_FILES”，所以我将我的 QML 文件的所有路径添加到它，但问题仍然存在。
我还从我的智能手机中检索了 apk 并提取了内容。我注意到我的 apk 不包含一些存在于 apk 示例中的库：
libqml_Qt_labs_folderlistmodel_libqmlfolderlistmodelplugin.so
libqml_Qt_labs_settings_libqmlsettingsplugin.so

与你不同，我没有 src 目录，QML 文件被移动到 content 目录。我还有一个相同 QML 文件的资源文件，即 Qml.qrc。翻译文件（又名 .ts 文件）包含在带有源代码的主目录中。已编译的翻译（又名 .qm）文件位于子目录 translations.
中
目录 android 和 ios 包含特定于平台的文件，特别是我们有 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。
lib 目录包含每个平台的子目录以及该环境的重新编译库。
对应的工程文件如下：
