## What's new?
- Added Android platform support to PhysX 5.1.
- New build preset `android-arm64-v8a` added. Initial support focused on 64-bit arm8 architecture with NEON SIMD instructions.
- Support for generating PhysX as either static or dynamic libraries.
- New android platform readme.
## Out of Scope
The following points are considered out of scope, they can be added in the future:
- Support for PhysX Snippets.
- Support for Omniverse Visual Debugger (OmniPVD) .
- Support for other architectures: arm7, x86, x86_64.
- Support for other SIMD instructions set: SSE.
## Known Errors/Limitations
- The name of the bin folder for android will appear as `bin\UNKNOWN`. **To fix this nVidia has to modify the CMakeModules package it's downloaded from packman when building PhysX** (NVIDIA-Omniverse#59). The file that needs to be modified is `GetCompilerAndPlatform.cmake`, adding the following lines to the `if` condition inside `GetPlatformBinName` function:
````
ELSEIF(TARGET_BUILD_PLATFORM STREQUAL "android")
SET(RETVAL "android.${ANDROID_ABI}")
````
- PhysX Systems that require a CUDA capable GPU are not supported in Android, for example particle system or cloth simulation.
## Testing
- Built PhysX 5.1 successfully on android in debug, checked, profile and release using `PX_GENERATE_STATIC_LIBRARIES` set to both true and false. The right output binaries were generated in `bin/android.arm64-v8a`
- Built cmake `install` target successfully. It generated the correct output for Android under `install/android-29` folder, only including necessary headers for Android.
- Runtime tested using `Open 3D Engine (O3DE)` with an early integration [branch](https://github.com/aws-lumberyard-dev/o3de/tree/PhysX5Support). The following video shows O3DE running PhysX 5.1 on Android.

bin\UNKNOWN. To fix this nVidia has to modify the CMakeModules package it's downloaded from packman when building PhysX. The file that needs to be modified isGetCompilerAndPlatform.cmake, adding the following lines to theifcondition insideGetPlatformBinNamefunction:dyld[number]: missing symbol calledwhen run on an arm-based Mac. To fix this nVidia has to add an ARM python package for mac into the packman scripts. As a temporary solution, use your system's python adding the environment variablePM_PYTHON_EXTbefore building (for example by addingexport PM_PYTHON_EXT="python3"into your.bash_profilefile).Testing
