Getting Started with Qt for Android

Requirements

In order to useQt for Android, you need the following:

  • The Android SDK Tools
  • The Android NDK
  • Apache Antv1.8 or later
  • Java SE Development Kit(JDK) v6 or later. You can also useOpenJDKon Linux.
  • On Windows, you need the following additional installations:
    • MinGWv4.8.0 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 basicadbcommands and check whether your device responds to it.

Note:You must set theJAVA_HOMEenvironment 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 theandroidtool that comes with the SDK Tools package. For example, on Ubuntu the following command starts theAndroid SDK Manager, which enables you to select the packages you want to install:

./android update sdk

The Qt 5 installers for different platforms are available from theDownloadspage. Choose the one that is appropriate.
