Golang交叉编译到Android上运行

交叉编译

go程序：hello.go

package mainimport ("fmt"
)func main() {fmt.Println("Hello Android Golang.")
}

交叉编译

CGO_ENABLED=0 GOOS=android GOARCH=arm64 go build -o go_hello hello.go

使用adb传输到android手机上运行

# 传输
adb push go_hello /data/local/tmp/# 执行
adb shell 
cd /data/local/tmp/
./go_hello

android手机上运行结果
