android - Blank permission screen on login attempt -

-

i'm making android app allows users login facebook accounts. can run on emulator , log in , out of account perfectly. however, when tried same on actual android, when went login blank facebook dialog poped title "permissions". there's "okay" button @ top right of dialog, , when click gives me following error:

an error occurred [app name]. please try again later. api error code: 100 ape error description: invalid parameter error message: requires valid redirect uri.

my phone automatically logs me in because have facebook app installed on not emulator, whereas emulator have enter info every time.

this happens when try use same account both phone , emulator. different accounts each works fine

mate,

i've been fighting issue couple of days, , throw away project.

the problem resides in following setting:

app settings-> advanced settings -> enhanced auth dialog: true

if set value false, run charm. seems facebook guys testing non-working stuff us, without warning! default value true, set false , problem solved!

cheers.
