在机器人的Picasa访问：PicasaUploadActivity [英] Picasa access in android: PicasaUploadActivity

问题描述

我是新来的Andr​​oid，和我挣扎弄清楚到底是什么工具可以给我。 我正在开发针对Android 2.0.1现在，只因为那是我的设备上运行的内容。

I am new to Android, and I'm struggling to figure out exactly what tools are available to me. I am developing for Android 2.0.1 for now, just because that is what my device runs.

具体，我写一个应用程序，我想上传图片到的Picasa相册 。我几乎可以肯定，这是支持的;例如，内置的（谷歌？）照片浏览器有一个分享按钮，用Picasa的选项，甚至一个小一点的样本code，其中包括段

Specifically, I am writing an app that I would like to upload images to a Picasa album. I am almost sure this is supported; for example, the built in (Google?) photo viewer has a 'share' button with a Picasa option, and even a small bit of sample code, including the snippet

[借来的code！道歉，如果这是违反规则..] 的

temp.setComponent(new ComponentName 
("com.google.android.apps.uploader", 
"com.google.android.apps.uploader.picasa.PicasaUploadActivity")); 
startActivityForResult(temp, PICASA_INTENT) 

看起来像正是我想要的。

which looks like exactly what I want.

但我找不到任何文档的任何地方。我其实还不是很清楚如何使用此类型的资源。在Eclipse中，我需要有另外一个项目， com.google.android.apps.uploader ？如果是这样，我怎么得到它？我如何包括它？有没有为我提供任何工作示例code偷看？

But I can't find any documentation anywhere. I am in fact quite unclear how to use this type of resource. From within Eclipse, do I need to include another project, com.google.android.apps.uploader? If so, how do I get it? How do I include it? Is there any working sample code provided for me to peek at?

        Cursor cursor = contentResolver.query(uri, null, null, null, null);
        cursor.moveToFirst();
        content.type = intent.getType();
        content.length = cursor.getLong(cursor.getColumnIndexOrThrow(Images.Media.SIZE));
        HttpRequest request = requestFactory.buildPostRequest(new GenericUrl(
            "https://picasaweb.google.com/data/feed/api/user/default/albumid/default"), content);
        GoogleHeaders headers = new GoogleHeaders();
        request.headers = headers;
        String fileName = cursor.getString(cursor.getColumnIndexOrThrow(Images.Media.DISPLAY_NAME));
        headers.setSlugFromFileName(fileName);
        request.execute().ignore();
    }
    catch (IOException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
