Open Facebook app by a web link on Android

Question

I have a mobile site that the user can only access by logging in with Facebook. O SDK Facebook para Web (Javascript) works well, but the user always has to log in, because he is not always logged in to the Smartphone browser, IE, (for some users) is time consuming and difficult, and often he gives up access to the page for this reason.

Taking into account that the user is almost always logged into the Facebook App itself on Android, I would like to open this application through a Link, to facilitate user login on the page.

I did a search on the internet and found that it is possible to open the application through the Schema iOS, in this website, but I tested on Android and did not work.

It is possible to open the Android Facebook application and pass parameters to it?

Answer 1

The latest version of Facebook, launched this year, also comes from Scheme for Android, which uses the same parameters as iOS. Unfortunately through a URL I can’t pass the ID of my Facebook app to the Facebook Android App installed on Smartphone, making it impossible for the user to log in, as said in this question of Soen.

The only parameters I could pass were the ones I found on the site wiki.akosma.com, but it is currently offline. Below follows the information I got in free translation:

fb://profile           - Abre o perfil do usuário
fb://friends           - Abre a lista de amigos
fb://notifications     - Abre as notificações do Facebook
fb://feed              - Abre o feed de notícias
fb://events            - Abre a tela de eventos
fb://requests          - Abre as solicitações de amizade
fb://notes             - Abre a área de notas
fb://albums            - Abre uma lista de álbuns
fb://post/<post_id>    - Abre um post. Só funciona se o aplicativo do Facebook já tiver carregado a publicação em particular, caso contrário ela desenha um espaço em branco.

Below are other parameters without comments:

I believe that, for the execution of Login (Connect) from Facebook to your app/page, only possible if it’s only for the web or just for Java.
