The scripts will help you to cross-compile Assimp v5.0.0 for Android. It requires at least Android NDK r19, because it uses the NDK in-place toolchain. So one does not need to make a standalone toolchain for an arbitrary build system. Just get yourself a fresh NDK version and place it somewhere besides your Android Studio, if you missing an NDK version beyond r19.
The minimum SDK version depends on the ABI as follows:
| ABI | MIN_SDK_VERSION |
|---|---|
| armeabi-v7a | 16 |
| arm64-v8a | 21 |
| x86 | 16 |
| x86-64 | 21 |
If you want to support SDK versions below these named, you have to make a standalone toolchain.
The example builds shared and static libs for a 64-bit ARM Android (arm64-v8a) with a minimum SDK version of 21. The includes and binaries are found under assimp-for-android/build/arm64-v8a.
git clone https://github.com/kenomo/assimp-for-android.git
cd assimp-for-android
./download.sh
export ANDROID_NDK=PATH-TO-THE-ANDROID-NDK-FOLDER
export HOST_TAG=YOUR-HOST-TAG
./build.sh arm64-v8a 21 ON| NDK OS Variant | Host Tag |
|---|---|
| macOS | darwin-x86_64 |
| Linux | linux-x86_64 |
The build script takes at least 3 arguments defining the ABI, the MIN_SDK_VERSION and building either shared librarys (ON) or not (OFF). Static libraries will always be build.
./build.sh ABI MIN_SDK_VERSION BUILD_SHARED_LIBSIn addition one can turn ON or OFF Assimp importer and exporter.
By default, the following importer formats are enabled
- AMF 3DS AC ASE ASSBIN B3D BVH COLLADA DXF CSM HMP IRRMESH IRR LWO LWS MD2 MD3 MD5 MDC MDL NFF NDO OFF OBJ OGRE OPENGEX PLY MS3D COB BLEND IFC XGL FBX Q3D Q3BSP RAW SIB SMD STL TERRAGEN 3D X X3D GLTF 3MF MMD STEP
and the following exporter formats:
- 3DS ASSBIN ASSXML COLLADA OBJ OPENGEX PLY FBX STL X X3D GLTF 3MF ASSJSON STEP
They can be disabled by adding e. g.:
- -DASSIMP_BUILD_AMF_IMPORTER=OFF
- -DASSIMP_BUILD_3DS_EXPORTER=OFF
to the ./build.sh.
