Android
=======
For details on developing Go for Android, see the documentation in the
mobile subrepository:
https://github.com/golang/mobile
To run the standard library tests, see androidtest.bash. Run it as
CC_FOR_TARGET=$STANDALONE_NDK_PATH/bin/clang GOARCH=arm64 ./androidtest.bash
To create a standalone android NDK tool chain, follow the instructions on
https://developer.android.com/ndk/guides/standalone_toolchain
To run tests on the Android device, add the bin directory to PATH so the
go tool can find the go_android_$GOARCH_exec wrapper generated by
androidtest.bash. Then, use the same GOARCH as when androidtest.bash ran
and set GOOS to android. For example, to run the go1 benchmarks
export PATH=$GOROOT/bin:$PATH
cd $GOROOT/test/bench/go1/
GOOS=android GOARCH=arm64 go test -bench=. -count=N -timeout=T
