Getting Started with Qt for Android
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.
To learn the basics of getting started with Qt for Android, take the Getting Started with Qt for Android course in Qt Academy.
The rest of this page has more detailed getting started information.
To download and install Qt for Android, follow the instructions on the Getting Started with Qt page.
Android Development Prerequisites
In order to develop with Qt for Android, you will need the following prerequisites:
- Java Development Kit (JDK)
- Android Command Line Tools which includes:
- Android NDK: for building C++ code.
- Android SDK Platform and Android SDK Build Tools: for building Android apps for specific API version.
- Android SDK Platform Tools: for deploying and managing Android dependencies.
The easiest way to manage these dependencies is by using Qt Creator's built in Android development setup. For more information, see Qt Creator: Specifying Android Device Settings.
Manually Installing the Prerequisites
If you prefer to manually install the prerequisites please follow these next steps.
Java Development Kit (JDK)
Qt for Android development requires JDK 17 or above, provided by any of the following supported distributions:
Install your preferred JDK. If your installer doesn't set the JAVA_HOME environment variable that points to the location of the installed JDK, you can set it manually. For example on Linux:
sudo apt-get install openjdk-17-jdk export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64
Or on macOS:
brew install openjdk@17
sudo ln -sfn "$(brew --prefix openjdk@17)/libexec/openjdk.jdk" \
"/Library/Java/JavaVirtualMachines/openjdk-17.jdk"
export JAVA_HOME="$(/usr/libexec/java_home -v 17)"
Android SDK Command Line Tools
Download the latest version of the Android SDK Command Line Tools for your operating system and extract it to the appropriate path as stated below.
The Android SDK is commonly installed by Qt Creator or Android Studio in the following locations:
- Linux: ~/Android/Sdk/
- macOS: ~/Library/Android/sdk/
- Windows: C:\Users\<USER>\AppData\Local\Android\Sdk\
Or use your OS's package manager, for example for macOS:
brew install android-commandlinetool
Android SDK Mandatory Packages
Make sure to install the SDK Platform, Platform Tools, and Build Tools. For Qt 6.8, use:
sdkmanager "platform-tools" "platforms;android-34" "build-tools;34.0.0"
Android NDK
Qt 6.8 uses NDK 26.1.10909125, you can install it by running:
sdkmanager "ndk;26.1.10909125"
For example for macOS:
Emulator
If you wish to use the Android Emulator, you can install it by running:
sdkmanager "emulator" "patcher;v4"
Platform Specific Configurations
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 extras Android SDK package. Install it by running the following:
sdkmanager.bat "extras;google;usb_driver"
Linux
The following dependencies are needed for using tools such as adb or gdb which can be used by Qt Creator:
sudo apt-get install libstdc++6 libncurses5
To run the Android emulator, the following dependencies are also necessary:
Testing the Setup
Now you can test your development setup by running the examples shipped with the Qt installation. For more information, see Mobile Examples.
To develop a simple application from scratch, see Qt Creator: Creating a Mobile Application.
