What did you do?

• go get github.com/fatedier/frp
• vi {GOPATH}/github.com/fatedier/frp/cmd/frpc/sub/export.go

package sub

import (
	"time"
	"math/rand"

	_ "github.com/fatedier/frp/assets/frpc/statik"
	
	"github.com/fatedier/golib/crypto"
)
// I want to export this function only
func Start(filePath string) {
	crypto.DefaultSalt = "frp"
	rand.Seed(time.Now().UnixNano())

	runClient(filePath)
}

open terminal
gomobile bind -target android github.com/fatedier/frp/cmd/frpc/sub

What did you expect to see?

gomobile create a .aar and .jar file

What did you see instead?
