\title Building and Deploying Qt Applications for HarmonyOS
\brief How to package a Qt application into a HAP and deploy it to HarmonyOS.
\previouspage harmonyos-building.html

\note Qt for HarmonyOS is in technology preview and may change in future
releases.

This page describes how to build and package a Qt application for HarmonyOS,
and how to run it on a device or the emulator.

\section1 Packaging into a HAP

\note You can build Qt applications for HarmonyOS with either CMake or qmake,
but packaging an application into a HAP and deploying it is only supported with
CMake.

HarmonyOS applications ship as HarmonyOS Ability Packages (HAPs).
When you create a Qt application executable with
\l{qt6_add_executable}{qt_add_executable()} while targeting HarmonyOS, Qt
automatically generates a \c {<target>_make_hap} build target. Building that
target produces the HAP for your application:

\badcode
cmake --build . --target <target>_make_hap
\endcode

\section1 How deployment works

The \c {<target>_make_hap} target runs \c harmonydeployqt, the HarmonyOS
deployment tool. It follows the same approach as \l{The androiddeployqt
Tool}{androiddeployqt}: it collects the application's shared library, the
HarmonyOS platform plugin (\c libqohos.so), the required Qt modules, and, for Qt
Quick applications, the QML modules, and places them into a HarmonyOS
application template. It then invokes the OpenHarmony \c hvigor build tool to
assemble the final HAP.

To configure the metadata written into the HarmonyOS manifests (\c app.json5 and
\c module.json5) and to declare permissions, use the commands described in \l{Qt
for HarmonyOS CMake API}.

\section1 Running the application

Install and run the resulting HAP on a connected HarmonyOS device or on the
emulator. The most convenient way to deploy and debug is to open the generated
project in \l{https://developer.huawei.com/consumer/en/deveco-studio/} {DevEco
Studio} and use its run and debug tooling.
