Android generated LoginActivity error(Incorrect password)

Question

I am using the Android generated login activity and it keeps giving me incorrect password error even though my password is correct. I have checked my code several times but i can't find any errors. It just doesn't start my Home activity and reports the error. Can someone please check my code and correct me if i am doing something wrong...

**editted: Added full code

***editted: Solved this problem by checking my next activity which sets a session to redirect to login page when no session is logged in(apparently i missed that earlier on). Thanks for all the help though.
