私はアンドロイド開発に不慣れです。フェイスブックSDKも！問題は、アプリにfbオプションでログインがあることです。これでセッションが作成され、ログインに成功し、アクセス トークンとともにユーザーの詳細を取得できるようになりました。しかし、アプリにログインした後、いくつかのコンテンツを共有する必要があります。
そのため、ユーザーが Facebook でコンテンツを直接共有できるように、Facebook のアクティブなセッションをキャッチする必要があります。
コードを実行しましたが、このエラーが表示されます。誰かが抜け穴から私を助けることができますか?
ありがとう:)表示されているlogcatにエラーを貼り付けています。
