QBS和android

Question

我试图找到一个简单的教程:如何使用gbps为android制作一个简单的应用程序。发现了以下链接：

1. 叠流。这个问题的答案还没有收到，尽管cbs的版本已经更新到1.11，android的支持也包括在内。
2. QBS文档中的AndroidApk项目。在本例中，我收到警告：'../Application/src/main/AndroidManifest.xml' does not exist.

不幸的是，我找不到任何新的信息。我寻求帮助。

更新： For Qmake只创建标准小部件项目，如下所示：

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = androidtest
TEMPLATE = app

DEFINES += QT_DEPRECATED_WARNINGS

SOURCES += \
        main.cpp \
        mainwindow.cpp

HEADERS += \
        mainwindow.h

FORMS += \
        mainwindow.ui

CONFIG += mobility
MOBILITY = 

这是工程和建设很好。QtCreator自动创建所有必要的文件，而不是在我的手机上运行应用程序

在Qbs中，我试图提出同样的申请。由于这个原因，我有QBS-file：

import qbs

Project {
    CppApplication {
        name: "helloworld"

        Depends {
            name: "Qt"
            submodules: [
                "core",
                "widgets"
            ]
        }

        Depends { name: "Android.ndk" }
        Android.ndk.appStl: "gnustl_shared"

        Group {
            name: "src"
            files: [
                "main*.*"

            ]
        }
    }

    AndroidApk {
        name: "helloworld_android"
        Depends {name: "helloworld" }
        packageName: "com.example.android.helloworld"
    }
}

最后，我已经完成了HelloWorld产品(libhelloworld.so)。但是"helloworld_android“的第一个错误是在android清单上失败了。此文件未定义。我下一步该怎么办？

好吧，我想我成功了。这不是一个好的解决方案，但这是工作。在"\install-root\$productName$\build\outputs\apk\$productName$-debug.apk中可以找到由此产生的APK

Answer 2

在为Android构建时，qmake有一些内置的魔力，比如使用Qt提供的资源(包括清单模板)和运行Android-部署Qt工具。目前没有任何一项是由qbs完成的。

Answer 3

QBS 1.13于今年2月(2019年)发布，使得部署Android应用程序和使用qmake一样简单。在实践中，你不需要做任何特别的事情。例如，我使用了Qt示例中的contactlist应用程序并添加了这个QBS文件：

import qbs 1.0

Project {
    QtGuiApplication {
        name: "contactlist"
        install: true

        files: [
            "contactmodel.h",
            "contactmodel.cpp",
            "main.cpp",
        ]

        Group {
            files: [
                "*.qml",
                "designer/Backend/*.qml",
                "designer/Backend/qmldir",
            ]
            fileTags: ["qt.core.resource_data"]
        }

        Depends { name: "Qt.quick" }
    }
}

正如你所看到的，这里没有任何特定于Android的东西。我使用的唯一技巧是将标记qt.core.resource_data分配给QML文件，以便将它们编译为资源文件--但它甚至不是必需的。

使用qbs run，应用程序将在连接的安卓设备中运行。
