Method 1:

i) Go to facebook & Then Account setting.
ii) Click 'Apps & websites'
iii) Now ou will able to see number of apps & sites that was used & authorized by you. Find out 'facebook for android' from there & delete it.

Method 2: ( Only if method 1 does not work)

i) Deactivate your account.
ii) Reactivate it.
