esp8266

Hello can I connect my Android phone to esp8266 and arduino using wifi but without internet. Don't want to run server and HTML application. Kind of offline working of thing.

Please give any idea or link where I can study this and try for myself.

Yes you can connect to the esp8266 wifi.

You will need to set the esp8266 up as an access point

You can then communicate between the two using either a server client method as shown above or use UDP if you just want to send packets of data each way.
