Getting Started with Qt5 for Android
Getting Started with Qt for Android
Requirements
In order to use Qt for Android, you need the following:
- The Android SDK Tools
- The Android NDK
- Apache Ant v1.8 or later
- Java SE Development Kit (JDK) v6 or later. You can also use OpenJDK on Linux.
-
On Windows, you need the following additional installations:
- MinGW v4.8.0 revision 2
-
Android Debug Bridge (ADB) driver on the Windows platform to enable USB debugging. The default USB driver on Windows does not allow debugging. For details about how to get the USB driver, seehttp://developer.android.com/sdk/win-usb.html.
After installing the driver, try running a few basic adb commands and check whether your device responds to it.
Note: You must set the JAVA_HOME environment variable to the JDK install directory path so that Qt Creator finds the binaries required to build your application.
After installing these tools, update the Android SDK to get the API and tools packages required for development. You can update the SDK using the android tool that comes with the SDK Tools package. For example, on Ubuntu the following command starts the Android SDK Manager, which enables you to select the packages you want to install:
./android update sdk
Installing Qt for Android
The Qt 5 installers for different platforms are available from the Downloads page. Choose the one that is appropriate.
Note: Enterprise packages are available from the Try Qt Enterprise page. Qt for Android is also available as part of Qt Mobile Edition, see qt.digia.com for details.
Once you have the installer, follow these steps:
- Run the installer to begin installing Qt 5 on your development platform.
- Select the components you need in the Select Components screen and click Next.
- After the installation is complete, the installer lets you open Qt Creator and the README. Select to open Qt Creator and click Finish.
- Select Tools > Options > Android in Qt Creator to add the Android NDK and SDK paths. For more details, see Qt Creator Manual.
Now you can test your development setup by running the examples that came with the Qt 5 package installed earlier. You can browse the examples in Qt Creator Welcome mode. Use the android filter in the search field to list all the examples tested on Android.
