Caffe2 AICamera tutorial example

This is an example for using Caffe2 on Android. See the original README for details.

Using caffe2 from PyTorch master

PyTorch folder is at $PYTORCH_ROOT This repository folder is at $AICAMERA_ROOT Android NDK folder is at $ANDROID_NDK

Then, do the following:

1. Build caffe2 android libs and copy them over into AICamera app folder

# make sure $PYTORCH_ROOT, $AICAMERA_ROOT and $ANDROID_NDK are set
pushd $PYTORCH_ROOT

./scripts/build_android.sh
mv build_android build_android_arm

# copy headers
cp -r install/include/* $AICAMERA_ROOT/app/src/main/cpp/

# copy arm libs
rm -rf $AICAMERA_ROOT/app/src/main/jniLibs/armeabi-v7a/
mkdir $AICAMERA_ROOT/app/src/main/jniLibs/armeabi-v7a
cp -r build_android_arm/lib/lib* $AICAMERA_ROOT/app/src/main/jniLibs/armeabi-v7a/


./scripts/build_android.sh -DANDROID_ABI=x86
mv build_android build_android_x86

# copy x86 libs
rm -rf $AICAMERA_ROOT/app/src/main/jniLibs/x86/
mkdir $AICAMERA_ROOT/app/src/main/jniLibs/x86
cp -r build_android_x86/lib/lib* $AICAMERA_ROOT/app/src/main/jniLibs/x86/

2. Build the AICamera app using the Build -> Make Project menu option in Android Studio
