x/mobile: Build binaries for android.

[jcgruenhage]

It would be nice if we could build executable binaries for android using gomobile.

Is there any article on how to do this?...I am able to build binary for android by using GOOS=linux GOARCH=arm go build. The binary works, but libc api has problems since the default is to link with glibc i guess and android uses bionic. Is there a way to create a go binary linking to bionic?

I'm seeking the way developing on Android too:)

Ok sort of figured out...
I am first building the ndk-toolchain using
$(ANDROID_NDK_ROOT)/build/tools/make_standalone_toolchain.py --arch ${ARCH} --api 19 --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.
CC=$(TOOLCHAIN_DIR)/bin/clang CXX=$(TOOLCHAIN_DIR)/bin/clang GOOS=android GOARCH=$(ARCH) go build

for anyone looking to do same for ios.
CC=$(GOROOT)/misc/ios/clangwrap.sh CXX=$(GOROOT)/misc/ios/clangwrap.sh GOOS=darwin GOARCH=arm64 go build

Hope it helps

I'm going to close this. Building regular executables is out of scope for gomobile and can be done by setting up your own toolchains as demonstrated by @cosmosgenius.
