无法解决此错误。我在 libs 文件夹中安装了所需的 Lib 文件。

private void GetYTData ()
{

    YouTubeService ytservice = new YouTubeService("AppName",Dev_Key);   
}

线

YouTubeService ytservice = new YouTubeService("AppName",Dev_Key);

它给了我以下 Log cat 错误

java.lang.NoSuchMethodError:

您在 lib 文件夹中的 jar 似乎不包含任何方法copyOf

如果您的类路径中有旧/新（比您的代码）版本的 jar，则可能会发生这种情况。

我建议检查您用于此服务的 jar 版本。
