Android Youtube Player Api活動完成並創建

Question

我們已經使用Youtube api for android，但快速關閉並與youtube播放器和youtube播放器視圖打開同一活動存在問題。此問題也出現在示例應用程序中，當我嘗試打開富顯活動（無需單擊全屏按鈕）時，使用後退按鈕關閉活動並一次又一次。 Yutube應用程序崩潰。

10-11 15:14:53.313: E/ActivityThread(22537): Activity com.example.myvideo.FullscreenDemoActivity has leaked ServiceConnection 
com.google.android.youtube.player.internal.r$e@46095818 that was originally bound here 

我試圖重寫OnStop來釋放播放器，但沒有正面結果。請有人幫忙。

Fulscreen活動修改 - 原始和這一個之間的幾行差異。謝謝！

儘量供應應用Context，而不是的ActivityContext：

playerView.initialize(DeveloperKey.DEVELOPER_KEY, getApplicationContext()); 

這樣可能會消除你所面臨的MemoryLeak。原因因此Context然後不再綁定到生命週期Activity（這是銷燬），但在應用程序的生命週期。

如果您閱讀文檔getApplicationContext()它聲明，如果您需要生命週期與當前Context分開的Context，則應該僅使用此文檔。
