Problems updating the Android Facebook login

Question

I received an email from Facebook that my app's login via Facebook was using an old SDK and I need to update to a new one (version 9).

In my gradle I see this line:

implementation 'com.facebook.android:facebook-login:4.40.0'

which is the only line mentioning facebook (though I do the login using firebase

implementation 'com.firebaseui:firebase-ui-auth:4.3.1'

so that might be it)

Anyway, I looked on the Facebook Developer page here and it seems to say I should add this line

implementation 'com.facebook.android:facebook-login:[8,9)'

which looks odd to me because of the mismatched braces. Anyway, if I put that in I get an error on syncing:

Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not find any version that matches com.facebook.android:facebook-login:[8,9).

So, I'm unsure how to proceed to version 9 of the SDK. Does anyone know how to do this?

The highest numbers I got my gradle to accept were:

implementation 'com.facebook.android:facebook-login:7.+'

It's not clear to me how to get to version 9

Answer 1

Add this to Module-level /app/build.gradle before dependencies:

repositories {
  // You can also use jcenter if you prefer
  mavenCentral() 
}

Add the compile dependency you need with the latest version of the Facebook SDK in the build.gradle file:

dependencies { 
implementation 'com.facebook.android:facebook-login:[8,9)'
}

Or

Follow the below procedure to resolve the issue:-

1. Click on Project Structure from the icon available in the tool bar above.

2. Open Dependencies tab.

3. select com.facebook.android:facebook-login:[8,9)

4. Remove the facebook dependency by clicking the minus(-) button on the extreme right side.

5. Now, Click on Plus(+) button on the right side above Minus button. Select Library dependency

6. Type Facebook on the search input box and click on the search button.

7. Choose com.facebook.android:facebook-login . click on Ok. Sync your Gradle.
