arduino - android (WiFi)

Hello,

I made an Android app to communicate with an Arduino UNO + wifi shield. https://www.arduino.cc/en/Tutorial/WiFiWebServer

At this point I can send data from android to Arduino (via wifi), but I need a confirmation (acknowledge) that the message was successfully delivered ... I don't know how do this. .. Please help me to do this.

Thank you very much

You need to change your Android app (not relevant to this forum) and you need to change your Arduino sketch which you have not shown.
