我对 Qt 相当陌生，正在尝试构建一个简单的 Android 应用程序。我正在使用 Qt 5.7 使用评估包 Qt Creator 4.2.0 (Enterprise)。由于某种原因，在我通过 Projects->Build Settings->Build Android APK 'Create Templates' 创建了 AndroidManifest.xml 后，编译后出现以下错误，提示“ No Application .pro found, not build an APK ”

我试过查看 MakeFile 但目录看起来都不错。没有类型。

我的 .pro 文件如下：

#-------------------------------------------------
#
# Project created by QtCreator 2016-12-20T10:23:38
#
#-------------------------------------------------

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = AndroidApp2
TEMPLATE = app

# The following define makes your compiler emit warnings if you use
# any feature of Qt which as been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

CONFIG += mobility
MOBILITY = 

DISTFILES += \
    android/AndroidManifest.xml

ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android

使用 Qt 5.1，我似乎对此没有任何问题。

任何帮助都会很棒！

谢谢

根据 qt source qmakeandroidbuildapkstep.cpp有两种情况，一条消息：.pro 文件未找到和部署设置 .json 文件未找到

    const QmakeProjectManager::QmakeProFileNode *node = pro->rootProjectNode()->findProFileFor(proFilePathForInputFile());
    m_skipBuilding = !node;
    if (m_skipBuilding)
        return true;

    QString inputFile = node->singleVariableValue(QmakeProjectManager::Variable::AndroidDeploySettingsFile);
    if (inputFile.isEmpty()) {
        m_skipBuilding = true;
        return true;
}

我检查了 json 文件并在里面发现了一条消息 - 它打算由 androiddeployqt 读取。下一步非常简单：

/opt/Qt/5.9/android_armv7/bin/androiddeployqt --input android-libretroshare-qml-app.so-deployment-settings.json --release --verbose --gradle --stacktrace --debug --output ./

它根本不能解决我的问题，但它的信息非常有帮助。

有类似的问题是https://bugreports.qt.io/browse/QTCREATORBUG-13566通过在构建设置下禁用项目模式下不必要的“make install”和“Build apk”步骤来解决的。
