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.
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 also need the following prerequisites:
- Java Development Kit (JDK) for Java development
- Android SDK Command Line Tools for managing dependencies required for developing with Qt for Android, including:
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 11 or above, provided by any of the following supported distributions:
Please install your preferred JDK, and then make sure the
JAVA_HOME environment variable is pointing to the location of the installed JDK.
For example for Linux:
sudo apt-get install openjdk-11-jdk export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
Or for macOS:
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)"
Android SDK Command Line Tools
Install the latest version of the Android SDK Command Line Tools for your operating system, and verify that the installation succeeded by running the sdkmanager binary:
Then make sure the
ANDROID_SDK_ROOT environment variable is pointing to the location of the installed command line tools.
For example for macOS:
brew install android-commandlinetool export ANDROID_SDK_ROOT="$(brew --prefix)/share/android-commandlinetools"
The required version of the Platform, Platform Tools, and Build Tools for 6.5 is 31.
To install all of these run the following command:
sdkmanager "platforms;android-31" "platform-tools" "build-tools;31.0.0"
The required version of the Android NDK for 6.5 is 25.1.8937393.
To install the NDK run the following command:
Then make sure the
ANDROID_NDK_ROOT environment variable is pointing to the location of the installed NDK.
For example for macOS:
export ANDROID_NDK_ROOT="$(brew --prefix)/share/android-commandlinetools/ndk/23.1.7779620/"
If you wish to use the Android Emulator, you can install it by running:
sdkmanager "emulator" "patcher;v4"
Platform Specific Configurations
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. To install it, run the following:
After the package installation is complete, install the driver from
<ANDROID_SDK_ROOT>/extras/google/usb_driver. Try running a few basic adb commands now and check whether your Android device responds to them.
The following dependencies are needed for using tools such as
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:
sudo apt-get install libsdl1.2debian
Testing Your Setup
Now you can test your development setup by running the examples shipped with the Qt installation. For more information, see Qt for Android Examples.
To develop a simple application from scratch, see Qt Creator: Creating a Mobile Application.
