Answer 1

connect device to eclipse to see logcat. if log cat not running open cmd prompt in windows and run adb restart, (set the adb path first). then you can see logcat running. now open your app and click facebook login button. you can get the correct hash key in yellow colour in log cat. put that key on facebook and now facebook login will work on every device. thanks.
