About this page

On this page I describe how I build Qt Multimedia for Android on Windows.

See also Qt documentation at Qt for Android - Building from Source | Qt 6.7

My build setup

  • OS: Windows 11 with dev drive mounted on K: (Using a dev drive makes builds faster when using Windows Defender antivirus)
  • Qt source tree: K:\qt\android\qt6
  • Build directory main Android build: K:\qt\android\android
  • Main (host) build for dev branch: K:\qt\android\host
  • Visual Studio 2022 (MSVC)
  • Don't have perl in path as it can cause hard to understand build failures
  • Have cmake in path

Setting up Android SDK/NDK and JAVA

  1. Install Qt Creator with Android option using Qt Maintenance Tool
  2. In Creator preferences, install Adoptium JDK (C:\Program Files\Eclipse Adoptium\jdk-17.0.10.7-hotspot)
  3. Android SDK location: C:\Utils\Android
  4. Select Android NDK 26.1.10909125 and make default
  5. Oppenssl location: C:\Utils\Android\android_openssl
  6. Verify Android settings:

  1. Add Android device for ABI x86_64, OS Version 13.0 ("Tiramisu") (SDK 33)

Install MINGW

Run provisioning script from "K:\qt\android\qt6\coin\provisioning\common\windows\install-mingw.ps1" as administrator. This installs MINGW into C:\MINGW_PATH.

Building Qt for Android on Windows

Main build root Android: K:\qt\android\android

Follow steps in https://doc.qt.io/qt-6/android-building.html to create a host build. Note that only the host_tools target must be built.

Main build directory for Qt Multimedia on Android: D:\qt\build\androidmultimedia

Configure Qt Multimedia for Android

cmake-DCMAKE_TOOLCHAIN_FILE=D:\qt\build\android\qtbase\lib\cmake\qt6\qt.toolchain.cmake -G Ninja  -DQT_USE_ORIGINAL_COMPILER=ON -DQT_BUILD_TESTS=ON -DQT_BUILD_TESTS_BY_DEFAULT=OFF D:/qt/qt6/qtmultimedia & ninja

Importing Qt Multimedia build into QtCreator

  1. Open QtMultimedia CMakeLists.txt from D:\qt\qt6\qtmultimedia
  2. Deselect all kits
  3. Import build from D:\qt\build\androidmultimedia
    • This creates a Android Qt 6.8.0 (android) Clang x86_64 kit
    • Configure is run automatically again
  4. Select a test to be built (tst_qmediadevices) and choose a corresponding emulator in project build settings for Android kit
  5. Build target tst_qmediadevices
  6. Observe error message:
