運行約24小時後，Android VideoView在開始時出現斷斷續續的情況

Question

我有一個應用程序，用於在24x7循環中播放一系列視頻（這將安裝在Kiosk模式下）。一切似乎都在奏效，但在大約24小時運行後，視頻一開始就開始口吃。視頻直接從文件系統播放，所以網絡延遲不是問題。

我的日誌消息沒有顯示任何明顯的東西。當每個視頻開始時，我會得到其中一個：W/MediaPlayer﹕ info/warning (702, 0)。然後在視頻播放時大約每秒一秒：W/MediaPlayer﹕ info/warning (36865, 0)。我無法找到關於此第二個狀態代碼的任何信息。

我不懷疑有內存泄漏，因爲我的使用量持續徘徊在2.5MB左右。任何想法可能會造成這種情況？

編輯：我確實在全局logcat中找到了這些。它們在口吃期間發生。任何人都知道這意味着什麼和/或對解決方案有深入瞭解嗎？

Answer 1

這可能不是一個答案，而是一個建議。 我有類似的問題與基於amlogic的設備。

我正在製作的應用程序，它處理了大量的圖像和視頻直播流，基本上運行良好，直到設備已開啓24小時+，就像您提到的那樣。唯一解決了我的問題的就是切換到ART（Android Runtime），而不是Dalvik。
