I am using Facebook Login method for FireBase on my Android App. The error is the following: "Key hash B5dWUEYfZJL/...........jyA= does not match any stored key hashes". The error occurs when I have already installed the app, delete it and do a reinstall. The similar problem is described in the following link..
Facebook key hash does not match any stored key hashes
The suggested solution is to go to your Facebook Profile, delete the app from the permissions list in "Settings".like this..
The solution provided works and solves the problem, but you cannot go and ask a user of the app to go to his/her settings and delete app permissions when this happens.. Is there a way to avoid this problem in programming?
