I am trying to build an Android application on Opencascade with the help of below url.
http://www.opencascade.com/doc/occt-7.0.0/overview/html/samples_java_android_occt.html
Everything works fine except I am stuck in below errors :
07-12 17:13:09.711: E/occtJniViewer(16333): Error: native library "gnustl_shared" is unavailable:
07-12 17:13:09.711: E/occtJniViewer(16333): dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.opencascade.jnisample-2/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]] couldn't find "libgnustl_shared.so"
Error: native library "freetype" is unavailable:

Error: native library "freeimage" is unavailable:

Error: native library "TKernel" is unavailable:

I am not able to add gnustl_shared library and other .so files. Please suggest steps as the above link does not provide much detail about these.
Any help will be of great assistance.

Hi,
I saw your post + solution on http://stackoverflow.com/questions/38349139/opencascade-android-studio .
Any idea how I can run this project on an X86 emulator which should be much faster than arm7?
In case you have some Android Studio project examples for Android apps using open cascade I would love to get a reference for them - I'm trying to write a simple app that at the first stage will let the user to choose 2 different CAD files and the app will merge (fuse) them and render the result, and unfortunately I find it very hard to begin.
Thanks,
Joel

1. OCC libraries are not pre-compiled. I have tried to follow the steps from https://dev.opencascade.org/doc/overview/html/occt_dev_guides__building_android.html. Inside Cross-compilation toolchain for CMake in above url, building process only supports arme-abi versions. There is no support for X86. I wanted to build it but so far no luck. So instead I went ahead with arme-abi-v7 (since majority of Android handset support armabi7). Please let me know if you find any solution.
2. As far as I know, you can easily add two different types of CAD files easily. I have tested it with adding more than 2 step files in a single screen. You have to be careful with the origin of the files.
You can also try using Matrix to place the objects in your specified location.
I will try to send some code snippets if possible.
Please let me know in case of any issue.
