流Youtube視頻沒有Youtube應用程序

Question

有很多這樣的問題，我已經查看了所有這些問題，但沒有人有正確的答案，或正確的答案是過時的，由於YouTube的API更改。 在走出文檔領域找出最佳答案之前，我想問問你的流式傳輸YouTube視頻的方式是什麼？我認爲使用YouTube播放器API和限制用戶安裝的YouTube應用程式是非常可怕的做法

使用方法建議下面我得到和「抱歉，該視頻無法播放」，甚至通過我可以使用YouTube播放器API

@Datenshi你有沒有想過使用Android的YouTube API。他們有一個偉大的playerview，它給你很多控制和事件聆聽能力的視頻。我最近發佈了一個使用API​​的教程，如果它可能適合您的需求，請查看here
