Handler Failed to Bind

Hi H@ckeR$,

I was trying to hack an android phone with the help of the tutos on tag.wonderhowto.com but I hit an error which is "Handler Failed to bind to IP:4444, started reverse tcp handler on 0.0.0.0:4444......." I am unable to hack the phone (which is mine, just for testing). Both the Linux Machine and Phone are on the same wimax network, so I dont think it needs a forwarded port, I have successfully signed the apk, but this error is strucking again and again on my retrials,

Pls Help Guys..............
