Android example

To compile example to shared library you will need Android NDK. To build Android apk you will need Android SDK.

Export path to Android NDK, point to location where you have unpacked archive:

export ANDROID_NDK_HOME=/opt/android-ndk

Add toolchain bin directory to PATH:

export PATH=${ANDROID_NDK_HOME}/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin:${PATH}

Export sysroot path:

export ANDROID_SYSROOT=${ANDROID_NDK_HOME}/platforms/android-16/arch-arm

And compile shared library:

CC=arm-linux-androideabi-gcc \
CGO_CFLAGS="-D__ANDROID_API__=16 -I${ANDROID_NDK_HOME}/sysroot/usr/include -I${ANDROID_NDK_HOME}/sysroot/usr/include/arm-linux-androideabi --sysroot=${ANDROID_SYSROOT}" \
CGO_LDFLAGS="-L${ANDROID_NDK_HOME}/sysroot/usr/lib -L${ANDROID_NDK_HOME}/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/ --sysroot=${ANDROID_SYSROOT}" \
CGO_ENABLED=1 GOOS=android GOARCH=arm \
go build -tags static -buildmode=c-shared -ldflags="-s -w -extldflags=-Wl,-soname,libexample.so" -o=android/libs/armeabi-v7a/libexample.so

To build apk export path to Android SDK, point to location where you unpacked archive:

export ANDROID_HOME=/opt/android-sdk

And build apk:

./gradlew assembleDebug

If everything is successfully built apk can be found in android/build/outputs/apk/debug directory.
