|  | 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, enable Cgo and use an appropriate | 
|  | C compiler from the Android NDK. For example, | 
|  |  | 
|  | CGO_ENABLED=1 \ | 
|  | GOOS=android \ | 
|  | GOARCH=arm64 \ | 
|  | CC_FOR_TARGET=$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang \ | 
|  | ./all.bash | 
|  |  | 
|  | To run tests on the Android device, add the bin directory to PATH so the | 
|  | go tool can find the go_android_$GOARCH_exec wrapper generated by | 
|  | make.bash. 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 |
