このステートメントには誤りがあります
mHttpOauthprovider = new DefaultOAuthProvider("https://api.twitter.com/oauth/request_token", "https://api.twitter.com/oauth/access_token", "https://api.twitter.com/oauth/許可する");
コンストラクタDefaultOAuthProvider (String, String, String) は未定義です
mAccessToken = mSession.getAccessToken();
タイプの不一致: twitter4j.auth.AccessTokenから twitter4j.http.AccessToken に変換できません
そして、どこに問題があるのか わかりません!助けてください
