    Qt for Android enables you to develop Qt applications for Android devices,
    and supports a wide range of features and use-cases.

    To download and install Qt for Android, follow the instructions on the
    \l{Getting Started with Qt for Android} page. To build Qt from source,
    see \l{Qt for Android - Building from Source}{Building from Source}.

        \endtable

    \note Qt for Android support is inclusive of \b{but not limited to} these devices.

    \note The above table is accurate at the time of this Qt patch release only.
    It may change during the patch release cycle and should only be used as a
    reference for what the Qt Company can rapidly reproduce bugs on.

    \section1 Where to Go from Here

    We invite you to explore the rest of Qt. We prepared overviews which help
    you decide which APIs to use and our examples demonstrate how to use our
    APIs.

    The video below is a beginner's guide to using the Qt for Android toolchain,
    including the Qt Creator IDE, to get you started developing Android apps.

    The rest of this page has more detailed getting started information.

    To download and install Qt for Android, follow the instructions on the
    \l{Getting Started with Qt} page.

    \section1 Android Development Prerequisites

    In order to develop with \l{Qt for Android}, you will also need the following
    prerequisites:

    \list
        \li Java Development Kit (JDK) for Java development
        \li \l{Android: Android command line tools}{Android SDK Command Line Tools}
            for managing dependencies required for developing with Qt for Android,
            including:
            \list
                \li \l{Android: Android SDK Platforms}{Android SDK Platform}
                \li \l{Android: Android SDK Platform Tools}{Android SDK Platform Tools}
                \li \l{Android: Android SDK Build Tools}{Android SDK Build Tools}
                \li \l{Android: The Android NDK}{Android NDK}
            \endlist
    \endlist

    The easiest way to manage these dependencies is by using Qt Creator's built in
    Android development setup. For more information, see
    \l{Qt Creator: Specifying Android Device Settings}.

    \section2 Manually Installing the Prerequisites

    If you prefer to manually install the prerequisites please follow
    these next steps.

    \section3 Java Development Kit (JDK)

    Qt for Android development requires JDK 11 or above, provided by any of the
    following supported distributions:

    \list
        \li \l{AdoptOpenJDK}
        \li \l{OpenJDK}
        \li \l{Java SE Development Kit}
    \endlist

    Please install your preferred JDK, and then make sure the \c JAVA_HOME
    environment variable is pointing to the location of the installed JDK.

    For example for Linux:

    \badcode
        sudo apt-get install openjdk-11-jdk
        export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
    \endcode

    Or for \macOS:

    \badcode
        brew install openjdk@11
        sudo ln -sfn "$(brew --prefix openjdk@11)/libexec/openjdk.jdk" "/Library/Java/JavaVirtualMachines/openjdk-11.jdk"
        export JAVA_HOME="$(/usr/libexec/java_home -v 11)"
    \endcode

    \section3 Android SDK Command Line Tools

    Install the latest version of the
    \l{Android: Android command line tools}{Android SDK Command Line Tools}
    for your operating system, and verify that the installation succeeded by running
    the \l{Android: sdkmanager}{sdkmanager} binary:

    \badcode
        sdkmanager --version
    \endcode

    Then make sure the \c ANDROID_SDK_ROOT environment variable is pointing to the
    location of the installed command line tools.

    For example for \macOS:

    \badcode
        brew install android-commandlinetool
        export ANDROID_SDK_ROOT="$(brew --prefix)/share/android-commandlinetools"
    \endcode

    \section3 Android SDK

    The required version of the Platform, Platform Tools, and Build Tools for \QtVer is 31.

    To install all of these run the following command:

    \badcode
        sdkmanager "platforms;android-31" "platform-tools" "build-tools;31.0.0"
    \endcode

    \section3 Android NDK

    The required version of the Android NDK for \QtVer is 23.1.7779620.

    To install the NDK run the following command:

    \badcode
        sdkmanager "ndk;23.1.7779620"
    \endcode

    Then make sure the \c ANDROID_NDK_ROOT environment variable is pointing to the
    location of the installed NDK.

    For example for \macOS:

    \badcode
        export ANDROID_NDK_ROOT="$(brew --prefix)/share/android-commandlinetools/ndk/23.1.7779620/"
    \endcode

    \section3 Emulator

    If you wish to use the \l{Android: Android Emulator}{Android Emulator},
    you can install it by running:

    \badcode
        sdkmanager "emulator" "patcher;v4"
    \endcode

    \section3 Platform Specific Configurations

    \section4 Windows

    The default USB driver on Windows does not allow debugging using
    Android Debug Bridge (ADB) tool. You must install the additional USB driver
    provided by the \e extras Android SDK package. To install it, run the following:

    \badcode
        sdkmanager.bat "extras;google;usb_driver"
    \endcode

    After the package installation is complete, install the driver from
    \c{<ANDROID_SDK_ROOT>/extras/google/usb_driver}. Try running a few basic
    \l{Android: adb}{adb} commands now and check whether your Android device
    responds to them.

    \section4 Linux

    The following dependencies are needed for using tools such as \c adb or \c gdb which
    can be used by Qt Creator:

    \badcode
        sudo apt-get install libstdc++6 libncurses5
    \endcode

    \target emulator dependencies
    To run the Android emulator, the following dependencies are also necessary:

    \badcode
        sudo apt-get install libsdl1.2debian
    \endcode

    \section3 Testing Your Setup

    Now you can test your development setup by running the examples shipped with the
    Qt installation. For more information, see \l {Qt for Android Examples}.

    To develop a simple application from scratch, see
    \l {Qt Creator: Creating a Mobile Application}.
