Android App to connect to a specific Wifi

I need a simple app with one and only button, when I hit the button I need the app to do the following: 1-Enable WiFi (if not enabled). 2-Connect directly to a specific network(SSID and password will be provided). After enabling the WiFi, the phone would normally automatically connect to networks that are in range if they are previously configured, so the phone might not prefer the specific network that I intend to connect to, and automatically connect to another network. Bottom line, I need the app to force the phone to connect to my specific network even if there are several saved networks available in the area(and directly i.e: without connecting to another network, then disconnecting from it to connect to my specific network). Note: The WiFi network intended doesn't provide an Internet connection if that is of any concern to you.
