Build on Android* Systems

This section describes how to build Inference Engine for Android x86 (64-bit) operating systems.

Software Requirements

• [CMake]* 3.13 or higher
• Android NDK (this guide has been validated with r20 release)

NOTE: Building samples and demos from the Intel® Distribution of OpenVINO™ toolkit package requires CMake* 3.10 or higher.

Build Steps

1. Download and unpack Android NDK: https://developer.android.com/ndk/downloads. Let's assume that ~/Downloads is used as a working folder.

cd ~/Downloads
wget https://dl.google.com/android/repository/android-ndk-r20-linux-x86_64.zip

unzip android-ndk-r20-linux-x86_64.zip
mv android-ndk-r20 android-ndk

2. Clone submodules

cd openvino
git submodule update --init --recursive

3. Create a build folder:

  mkdir build

4. Change working directory to build and run cmake to create makefiles. Then run make.

cd build

cmake .. \
  -DCMAKE_TOOLCHAIN_FILE=~/Downloads/android-ndk/build/cmake/android.toolchain.cmake \
  -DANDROID_ABI=x86_64 \
  -DANDROID_PLATFORM=21 \
  -DANDROID_STL=c++_shared \
  -DENABLE_OPENCV=OFF

make --jobs=$(nproc --all)

• ANDROID_ABI specifies target architecture (x86_64)
• ANDROID_PLATFORM - Android API version
• ANDROID_STL specifies that shared C++ runtime is used. Copy ~/Downloads/android-ndk/sources/cxx-stl/llvm-libc++/libs/x86_64/libc++_shared.so from Android NDK along with built binaries
