To build obfs4proxy and get android ".so's" :

git clone https://gitlab.com/yawning/obfs4.git

#docker is optional and you can run on virtually any distro with changing how to install packages #replace the first Android with the directory of your ANDROID_HOME

docker run -v $(pwd)/:/obfs4 -v /Android:/Android --network=host -it debian /bin/bash

#replace the ndk home with your own #make sure ndk directory exists

export ANDROID_NDK_HOME=/Android/Sdk/ndk/21.3.6528147

export ANDROID_HOME=/Android

apt-get update && apt-get install autotools-dev libsystemd-dev -y && apt-get install automake autogen autoconf libtool gettext-base systemd* -y && apt-get install autopoint git make pkg-config systemd build-essential -y && apt-get install automake libevent-dev libssl-dev zlib1g-dev libsystemd* -y && apt-get install gcc-arm-linux-gnueabihf -y && apt-get install golang -y && apt-get install python -y &&

cd obfs4

BUILD FOR ARM

export ARCH=arm export TOOLCHAIN_DIR=$(pwd)/$ARCH

#building the ndk-toolchain using

$ANDROID_NDK_HOME/build/tools/make_standalone_toolchain.py --arch ${ARCH} --api 21 --install-dir ${TOOLCHAIN_DIR}

#Then i needed to cross compile the golang std itself.

CC=$TOOLCHAIN_DIR/bin/clang CXX=$TOOLCHAIN_DIR/bin/clang GOOS=android GOARCH=$ARCH go install std

#Then build my own tool using.

CGO_ENABLED=1 CC=$TOOLCHAIN_DIR/bin/clang CXX=$TOOLCHAIN_DIR/bin/clang GOOS=android GOARCH=$ARCH go build -v -o obfs4proxy/obfs4proxy.${ARCH}.so ./obfs4proxy

BUILD FOR ARM64

export ARCH=arm64 export TOOLCHAIN_DIR=$(pwd)/$ARCH

#building the ndk-toolchain using

$ANDROID_NDK_HOME/build/tools/make_standalone_toolchain.py --arch ${ARCH} --api 21 --install-dir ${TOOLCHAIN_DIR}

#Then i needed to cross compile the golang std itself.

CGO_ENABLED=1 CC=$TOOLCHAIN_DIR/bin/clang CXX=$TOOLCHAIN_DIR/bin/clang GOOS=android GOARCH=$ARCH go build -v -o obfs4proxy/obfs4proxy.${ARCH}.so ./obfs4proxy

BUILD FOR X86

export ARCH=386 # this one has to be 386 because the build command doesn't know what x86 is export TOOLCHAIN_DIR=$(pwd)/$ARCH

#building the ndk-toolchain using

#this one has to be x86

$ANDROID_NDK_HOME/build/tools/make_standalone_toolchain.py --arch x86 --api 21 --install-dir ${TOOLCHAIN_DIR}

#Then i needed to cross compile the golang std itself.

CC=$TOOLCHAIN_DIR/bin/clang CXX=$TOOLCHAIN_DIR/bin/clang GOOS=android GOARCH=$ARCH go install std

#Then build my own tool using.

CGO_ENABLED=1 CC=$TOOLCHAIN_DIR/bin/clang CXX=$TOOLCHAIN_DIR/bin/clang GOOS=android GOARCH=$ARCH go build -v -o obfs4proxy/obfs4proxy.x86.so ./obfs4proxy

BUILD FOR X86_64

#this one has to be amd64 because the build command doesn't know what x86_64 is

export ARCH=amd64 export TOOLCHAIN_DIR=$(pwd)/$ARCH

#building the ndk-toolchain using

#this one has to be x86_64

$ANDROID_NDK_HOME/build/tools/make_standalone_toolchain.py --arch x86_64 --api 21 --install-dir ${TOOLCHAIN_DIR}

#Then i needed to cross compile the golang std itself.

CC=$TOOLCHAIN_DIR/bin/clang CXX=$TOOLCHAIN_DIR/bin/clang GOOS=android GOARCH=$ARCH go install std

#Then build my own tool using.

CGO_ENABLED=1 CC=$TOOLCHAIN_DIR/bin/clang CXX=$TOOLCHAIN_DIR/bin/clang GOOS=android GOARCH=$ARCH go build -v -o obfs4proxy/obfs4proxy.x86_64.so ./obfs4proxy

The ".so's" will be in obfs4/obfs4proxy/obfs4proxy.{arch}.so
