youtube data api v3 android抽象googleclientrequest.execute（）ioexception

Question

我想在android應用程序上搜索youtube視頻。我使用YouTube數據api v3。我使用示例代碼https://developers.google.com/youtube/v3/code_samples/java#search_by_keyword

我得到IOException異常在這條線：

// Call the API and print results. 
SearchListResponse searchResponse = search.execute();

我logcat的輸出：

08-30 01:55:14.726: E/bestsongs(14223): IOException: null : null : null 

我檢查了類似的問題，我已經：

• 試圖爲服務器應用程序，而不是重點重點Android應用程序
• 試圖爲主要瀏覽器應用程序，而不是主要的Android應用程序
• 檢查SHA1和包名

有什麼建議？我想要做的就是在Android應用程序的YouTube上搜索視頻。提前致謝。

Answer 1

解決：您需要使用瀏覽器鍵訪問YouTube數據API。 Android密鑰僅用於Youtube Player。

另外：

您可以嘗試刪除你的項目和重置谷歌開發者控制檯上的一切從頭開始。

我在asynctask中實現了搜索功能。
