Facebook Partage avec android studio

Question

Chers gens de la stackoverflow,

Je crains d'avoir besoin d'aide. Il y a un problème que je continue à rencontrer avec mon application. Je fais une application qui a trois boutons: un pour voir un lien, un pour l'intention et un pour le partage de choses sur facebook (la raison en est que vous ne pouvez plus envoyer des choses avec intention, ou alors on m'a dit Cependant, selon le site Web du développeur Facebook, je devrais obtenir un bouton de partage. Avec mon code, tout se bloque et la seule chose que je peux voir, c'est le dialogue de partage. Ma question est, quelle est la principale erreur que j'ai faite?

Mon principal code d'activité:

     android:label="@string/app_name" /> 
    android:debuggable="true" 
</application> 

</manifest> 

Désolé pour le long poste, je sais que la réponse est là, mais ne trouve pas l'erreur greemly et cela m'a dérangé pendant une semaine.

Merci d'avoir lu!

Answer 1

Bon, après quelques travaux, j'ai trouvé la réponse. La réponse est très simple: au lieu de ceci:

super.onCreate(savedInstanceState); 
FacebookSdk.sdkInitialize(getApplicationContext()); 

Mais ce que vous devez faire est la suivante:

FacebookSdk.sdkInitialize(getApplicationContext()); 
super.onCreate(savedInstanceState); 

La raison de cela, est parce que vous voulez initialiser le SDK Facebook avant vous créez l'instance d'application, sinon, le SDK Facebook ne peut jamais être utilisé par l'application.

J'espère que si quelqu'un a le même problème que moi, peut l'utiliser!
