AppAuth provides both an Android and iOS client SDK for authenticating users with OpenID Connect, which Keycloak supports.

To the question of how to get the access token after successful social login, I’m assuming you mean the access token from the third-party provider like Google. Make sure you configure the identity provider with “Store Tokens” and “Store Tokens Readable” enabled. Once the user has logged in, you can get the provider token with:

GET /auth/realms/{realm}/broker/{provider_alias}/token
