|  | 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 |
