I am suffering with Facebook login issue in my android app. If there is no Facebook app installed on android device or I use an emulator, Facebook login works properly. But if Facebook app is installed on Mobile than it gave an error.
Error in facebook lite app
Error in facebook app
I am using 2 different mobile and both gave same error. I followed this SO question : Android Facebook sample app doesn't login when FB app installed. With this SO Question I understood that this error arise after Generating signed apk in android studio. So I used signed Keystore (.jks) to generate new Key Hash. After generating new key hash I added this in facebook app>Settings>Basic But Still getting same error in Both mobiles. How can I fix this error. Thanks in advance.androidfacebookfacebook-loginandroid-facebookandroid-keystore
You need configure app setting in facebook developer concole and add the generated KeyHash in KeyHash field.
keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | "PATH FOR openssl.exe" sha1 -binary | openssl base64 Password: android
No need to use android as your password, use that password that created during genrating signed apk
