Is your phone creating a WiFi hotspot? Which WiFi shield are you planning to use? Can it create a hotspot?

No

NRF24 is for communication between two or several Arduinos.

You might consider using Bluetooth. A Bluetooth module costs about the same as an NRF24, and there is a wealth of Android apps for Bluetooth.

in my previous version I use the bluetooth connection
but now i need to decrease the range of connection by using wifi connection
(arduino connect to wifi switch or router via wifi module > wifi switch or router connect to computer or android phone) can this achive?! or any procedure like this?

can this achive?

Yes, the Arduino, with appropriate WiFi shield, can connect to an existing WiFi network. What it may, or may not, be able to do is CREATE a WiFi network.

The phone needs to be able to connect to the SAME WiFi network.
