Building and Running VoltAir

Please make certain you have followed the steps in Configuring Qt Creator.

At this point, VoltAir is like any other Qt project. It can be built and run via the Build Project "VoltAir" menu item. For additional information please visit the following Qt Creator documentation about building and running.

This process is best described in Qt Creator online documentation. Please visit the following sites for additional information:

The following screenshot shows the expected kit chooser display:

Building an APK from the Command Line

A convenience script exists in the build directory that allows one to build an Android APK of VoltAir from the command line. The script is called build_android.py. One can learn of the script's options with the --help option. For example:

% build/build_android.py --help
usage: build_android.py [-h] --build-dir BUILD_DIR
                        [--voltair-root VOLTAIR_ROOT] --liquidfun-root
                        LIQUIDFUN_ROOT --qt-root QT_ROOT --jdk JDK --sdk-root
                        SDK_ROOT --ndk-root NDK_ROOT
                        [--ndk-platform NDK_PLATFORM] --ant ANT
                        [--num-processes NUM_PROCESSES] --output-apk
                        OUTPUT_APK

Build VoltAir.apk

optional arguments:
-h, --help            show this help message and exit
--build-dir BUILD_DIR
                        directory in which to build
--voltair-root VOLTAIR_ROOT
                        Location of VoltAir source code
--liquidfun-root LIQUIDFUN_ROOT
                        directory in which liquidfun is located
--qt-root QT_ROOT     Dir for Qt (>= Qt 5.3)
--jdk JDK             Java Development Kit location
--sdk-root SDK_ROOT   Android SDK location
--ndk-root NDK_ROOT   Android NDK location
--ndk-platform NDK_PLATFORM
                        Android platform (must be >= android-18)
--ant ANT             ant binary location
--num-processes NUM_PROCESSES
                        Number of processes to use for 'make'
--output-apk OUTPUT_APK, -o OUTPUT_APK
                        Destination of produced APK

And here is an example of the options that will produce an APK. This example matches the Qt Creator settings for the various modules found in Configuring Qt Creator:

% build/build_android.py \
    --build-dir=build-VoltAir \
    --qt-root=/Users/username/Qt5.3.1/5.3 \
    --jdk=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home \
    --sdk-root=/Applications/adt-bundle-mac-x86_64-20130729/sdk \
    --ndk-root=/Applications/android-ndk-r9b \
    --ant=/usr/local/bin/ant \
    --liquidfun-root=/usr/local/liquidfun \
    --num-process=8 \
    --output-apk=/tmp/VoltAir.apk
