In this post we will explain how to compile a Gin web server for Android using a Mac.

1. If you have already installed Go, you will need to remove it first.
   $ brew remove go

2. First of all, you will need to build the compilers, using:
   $ brew update
$ brew install go --cross-compile-common

3. Check that your Go installation enviroment is ok running:
   $ go env

4. Install Gin framework:
   $ go get github.com/gin-gonic/gin

5. Create a simple web server using Gin, listening on port 8080:
   $ nano main.go

   package main
   
   import "github.com/gin-gonic/gin"
   
   func main() {
       r := gin.Default()
       r.GET("/ping", func(c *gin.Context){
           c.String(200, "pong")
       })
   
       // Listen and server on 0.0.0.0:8080
       r.Run(":8080")
   }
   

6. Compile your program using:
   $ GOARCH=arm GOOS=linux go build main.go

7. Copy the binary file to an executable place in your ROOTED Android, give it permissions and run it:
   $ su
# ./main
