安装Facebook应用后，Facebook登录中断

Question

I'm building an Android app that allows the user to log in with his facebook account. I followed the official tutorial and got it working perfectly. That is untill I installed the facebook app on my phone. When I try to log in and I press "log in with facebook" button I get a screen switch for half a second and then I get back to my login screen where I was before.

If I uninstall the app everythings works again. I believe the app is interfearing but I don't know how to handle it, I have found no one with my same problem.

I follow the official tutorial step by step, I have a main activity with a fragment containing a button. Usually if you click the button the facebook login screen pops up and you're able to enter your credential.

Anyone know how to handle this?

Do you add you application package and hash to Android facebook app on developers.facebook.com ? If you login using SDK UI, not installed Facebook app - key does not checked.
