OCCT AndroidQt sample for Android

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,, 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 project-file:

File -> Open file or Project...

Specify Android configurations:

  • 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

Tools->Options->Build & Run

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

the paths to the headers:

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

the libraries location:

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.
