I am getting this error. When I try to sign in with facebook to my app. When I first time authentication it will correctly working. After I unistalled my application and now trying to sign in with Facebook on that I am getting this error.
Another Issue : After authenticate in device1 and try to login with facebook on device2 also same error is getting.
Solution I Found : when I remove App authentication from Facebook App Settings it is working in above scenario's but this is not an good solution how we can tell to users to do this action?
btnFbLogin.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(accessToken != null) { boolean expires = accessToken.isExpired(); if(!expires) { performFbLoginOrSignUp(accessToken); } } else { LoginButton loginButton = (LoginButton) findViewById(R.id.login_button); callbackManager = CallbackManager.Factory.create(); if (loginButton != null) { loginButton.setReadPermissions("public_profile", "email", "user_friends"); if (CommonUtil.isConnectingToInternet(LoginActivity.this)) { loginButton.performClick(); loginButton.setPressed(true); loginButton.invalidate(); loginButton.registerCallback(callbackManager, mCallBack); loginButton.setPressed(false); loginButton.invalidate(); } } } } });
In Facebook example also having an issue : GitHub link of Facebook example
Steps to reproduce :
Launch the app Login with Facebook Authenticate FB profile.
Un_install the app and install again.
Now try to Login with Facebook.
If you're having trouble logging into your Facebook account from your Facebook app: Make sure that you have the latest version of the Facebook app, or delete the app and then reinstall it. Try logging in from a mobile browser (example: Safari, Chrome).
Change your password or send yourself a password reset email. Turn on two-factor authentication for additional security. Confirm your phone number and email address in account settings are correct. Check Accounts Center and remove any linked accounts you don't recognize.
ANSWER
Just throwing this out there for people still experiencing this issue. The hash I created through the keytool was somehow incorrect. I fixed it by doing the following:
If you already uploaded your app to the playstore and enabled "app signing by Google Play" there is a solution (at least this worked for me):
Release
click Setup
>
App integrity
App signing certificate
copy the SHA-1 certificate fingerprintOutput (base64)
My Apps
>
Your App Name
)Settings
>
Basic
Key Hashes
That should fix the issue.
UPDATE
The steps above should still fully work.
But if you do not want to paste your key on that website, here is an alternative to step 6,7,8 below:
here's a oneliner Node.js command to do the same:
node -e 'console.log(Buffer.from(process.argv[1].split(":").map(hex => parseInt(hex, 16))).toString("base64"))' '5E:8F:16:06:2E:A3:CD:2C:4A:0D:54:78:76:BA:A6:F3:8C:AB:F6:25'

The error occurs because of invalid hash key.
We can create Hash key using the below command and update the same here under Settings-> Basic -> Android HashKeys
keytool -exportcert -alias ADD_RELEASE_KEY_ALIASE_HERE -keystore ADD_UR_KEYSTORE_PATH_HERE | openssl sha1 -binary | openssl base64
You can find the Relase Key Alias of your keystore using the below command if needed:
keytool -list -keystore ADD_UR_KEYSTORE_PATH_HERE
I have also experience an issue like by using the above HashKey the login works fine if I install the release APK directly to the device, But when I upload the APK to Play Store and install app from store then it shows the same Login failed error. The fix for this is as follows:
Go to Release Management here
Select Release Management → App Signing
You can see SHA1 key in hex format App signing certificate.
Copy the SHA1 in hex format and convert it in to base64 format, you can use this link do that without the SHA1: part of the hex.
Go to Facebook developer console and add the key (after convert to base 64) in the
settings → basic → key hashes
