Android 调用优酷SDK上传视频

近期在研究用优酷的SDK来进行视频上传的功能，因为优酷的SDK仅仅是提供了一个上传的sample code，没有涉及到授权的过程。对于新手来说。可能很棘手。如今分享一下我的思路：

程序实现前我们先要到优酷开放平台下载SDK（下载地址：http://open.youku.com/down）

依据优酷SDK的说明，上传过程主要分为下面7个步骤：

1. 新建android项目，引入YoukuUploadSDK-android jar包

2. 在MainActivity.java文件加入代码如sample.java所看到的，加入相关參数

3. 目录layout下activity_main.xml加入控件

4. 生成代码（xml文件代码）

5. 连接android手机执行android项目生成apk（切记开启开发人员选项usb调试等）

6. 授权过程(获取access_token)

7. 点击upload上传

其它的几步依照文档来做，应该不会有问题，以下重点说说步骤6的授权过程。

我们仅仅能採用通用授权的方式(合作级别的授权方式须要收费)，关于授权机制。请參考http://open.youku.com/docs/OAuth2.html。

大概思路就是，通过一个WebView来显示授权页面获取授权码（code），我们须要使用http方法get的方式来获取授权码(code)，所需的參数请參考http://open.youku.com/docs/OAuth2.html?id=101。然后通过使用授权码（code）来交换令牌即所谓的access_token，最后通过access_token来获取上传的权限。

代码例如以下看代码：

	    super.onDestroy();
	    }
	 
}

通过上述方法，我们能够非常easy地获取优酷上传视频所须要的access_token。获取了access_token以后，我们就能够将access_token设置到params的參数中，这样我们就能实现上传视频到优酷了。例如以下：

		percent = (TextView) findViewById(R.id.percent);

		uploader = YoukuUploader.getInstance(CLIENT_ID, CLIENT_SECRET, getApplicationContext());
		bindEvents();
		
	}

	private void bindEvents() {

					});
				}
			});
			tt.start();
			break;

		case R.id.cancel:
			if (uploader.cancel()) {

				percent.setText("");
			}
			break;
