我想完成Android SDK的初學者教程。我做了所有的通道，並沒有生成錯誤occours，但啓動應用程序，當我嘗試與Facebook進行身份驗證，在logcat中，我發現「登錄失敗」登錄失敗的Spotify Android SDK教程

任何想法解決這個問題？我已經嘗試從我的Facebook帳戶刪除應用程序，但理智最多，總是「登錄失敗」
更新1
我已經打印出異常的消息勞克的onLoginFailed方法：
06-21 18:53:59.362 28201-28201/com.example.lucabrognara.spotify_prova D/MainActivity﹕ Login failed: The operation requires a Spotify Premium account
我不知道爲什麼登錄我需要一個溢價賬...
更新2
我明確要求一個測試帳戶和the answer，我猜，關閉這個問題：
問：「有一種方法可以使用測試帳戶？我開發一個Android應用程序，我需要的Spotify認證」
答：‘沒有@lucabro，恐怕你需要有一個Spotify的高級賬戶才能使用此SDK’
我想你應該在[Spotify的Android SDK中的GitHub項目]這個文件（https://github.com/spotify/android-sdk）。 –
