一、在Activity下宣告Intent，居然提示”Accidental override: The following declarations have the same JVM signature”

圖片

解釋：說的是超類中已經聲明瞭這個intent，所以只要將intent這個物件名重新命名即可。

private val intentService: Intent? = null

二、宣告ServiceConnected的方法

private val conn = object : ServiceConnection {

        //繫結服務，回撥onBind()方法
 

        @SuppressLint("WrongConstant")
        override fun onServiceConnected(name: ComponentName, service: IBinder) {
            myAidl= IMyAidlInterface.Stub.asInterface(service)
            Toast.makeText(this@MainActivity, myAidl!!.add(4,5).toString(),Toast.LENGTH_LONG).show()

        }

        override
 
 fun onServiceDisconnected(name: ComponentName) {
            myAidl = null
        }

    }
