starting with APP Inventor : direct wifi communication with wifi devices

i'm starting with app inventor and have a very single problem: . my project is to developp android application to command an arduino uno using direct wifi transmission between android device and an arduino uno (connected to an ESP 8266 module/shield) . after opening the app inventor interface , in the connectivity palette i only find "bluetooth" or "web"  connectivity option but no wifi connectivity option . can someone help me to understand what to do = do i have to use" web" connectivity palet in this case  ???

NOTE : 
- ESP 8266 is configurated (with  AT &T commnand) as a wifi rooter with its own IP adress 
- wifi connection was choosen insted of bluetooth because off higher range level of transmission ...

thanks in advance

Bluetooth is the only way to communicate with an Arduino at the present.  It might be possible to use a personal server along with Web command but I doubt it.

What users know about hooking up and exchanging data with arduino is in these threads:   https://groups.google.com/forum/#!searchin/mitappinventortest/arduino$20communication

What you want to do with WIFI and Arduino might be impossible with App Inventor.

Thanks for answer ,

i'm so sorry , appinventor looked so nice and comfortable in first overall approach  ...
as a consequence   i've to continue to develop with android SDK tools ...

for example here a way ( video + arduino and android programms) to do the job with android studio or other android SDK:
