Android Facebook Login - WebView no longer supported

[iNdieboyjeff]

Facebook is no longer allowing login using WebView. If we use WebLoginActivity com.gigya.android.sdk.ui.WebLoginActivity then login with Facebook does not work. What can we do instead? Does this need to be resolved SDK side, or do we need to alter our implementation?

[tal-mi]

Facebook login requires implementing the Facebook SDK. If you do the SDK will not use the WebLoginActity. Please see: https://sap.github.io/gigya-android-sdk/sdk-core/#facebook

[iNdieboyjeff]

We already have all of that set up. It's still trying to use the WebLoginActivity

[tal-mi]

FacebookProvider class is responsible for selecting the correct social provider. Can you verify if it fails on the FacebookProvider.isAvailable call?

[iNdieboyjeff]

Do you want me to add this call to see what it does, or should there be something already in the logs?

This call is internal to the SDK. You are able to debug it. If you are prompt to use the WebLoginActivity when trying to login with Facebook there is an issue with your implementation. See the Kotlin example app for details.

FacebookProvider.isAvailable returns true

At the moment I'm failing to see anything that looks wrong from the documentation

[tal-mi]

If it return true then you are using the FacebookProvider to login and not the WebLoginProvider. Can you debug your implementation to verify where it is failing? What version of the SDK are you using?

[iNdieboyjeff]

Gigya SDK 5.1.4 Facebook 12.0.0

This looks to be the code snippet where we start the flow:

gigya.login( provider, mutableMapOf<String, Any>("forceAuthentication" to forceAuthentication), object : GigyaLoginCallback<GigyaAccount>() {

forceAuthentication defaults to false provider is "Facebook"

[iNdieboyjeff]

Hum, changing the provider from "Facebook" to "facebook" uses the Chrome custom tabs :(

[tal-mi]

Use GigyaDefinitions.Providers.FACEBOOK if you want to use the correct enum. I will make sure that in the upcoming version uppercase/lowercase will be handled.

[iNdieboyjeff]

OK, gracias.

[tal-mi]

Cheers.

[iNdieboyjeff]

Out of interest is there a way to bypass the app login, and force the use of Chrome Custom Tabs? We're seeing an issue where login works without the FB app installed, and fails if the FB app is installed. We're checking config to make sure there isn't an error, but it would be good to have this option as a fallback if necessary

[iNdieboyjeff]

I worked the bit above out, but I confirmed the config in FB was wrong, and correcting it seems to have worked.

I guess this issue can be closed, unless you want to keep it open for the case-sensitive provider name part.

[tal-mi]

I will keep it open until the SDK will fix the case-sensitive provider name issue on the next release. Thanks you.
