This sample demonstrates a simple way of using OCCT libraries in Android application written using Qt/Qml.

The connection between Qt/Qml and OCCT (C++) level is provided by proxy library, libAndroidQt.so, written in C++. The proxy library contains single C++ class AndroidQt encapsulating OCCT viewer and providing functionality to manipulate this viewer and to import OCCT shapes from supported format of CAD file (BREP).

Requirements for building sample:

Java Development Kit 1.7 or higher
Qt 5.3 or higher
Android SDK from 2014.07.02 or newer
Android NDK r9d or newer
Apache Ant 1.9.4 or higher

Configure project for building sample:

In QtCreator, open AndroidQt.pro project-file:

1 File -> Open file or Project...

Specify Android configurations:

1 Tools->Options->Android

In JDK location specify path to Java Development Kit
In Android SDK location specify path to Android SDK
In Android NDK location specify path to Android NDK
In Ant executable specify path to ant.bat file located in Apache Ant bin directory

Make sure that "Android for armeabi-v7a" kit has been detected

1 Tools->Options->Build & Run

The paths to OCCT and 3rdparty libraries are specified in "OCCT.pri" file:

the paths to the headers:

1 INCLUDEPATH += /occt/inc /3rdparty/include

2 DEPENDPATH += /occt/inc /3rdparty/include

the libraries location:

1 LIBS += -L/occt/libs/armeabi-v7a

OCCT resources (Shaders, SHMessage, StdResource, TObj, UnitsAPI and XSMessage folder) should be copied to androidqt_dir/android/assets/opencascade/shared/ directory. Current sample requires at least Shaders folder.

Select build configuration: Debug or Release and click Build->Build Project "AndroidQt" or (Ctrl + B). After successful build the application can be deployed to device or emulator.
