Android 中的 Picasa 访问：PicasaUploadActivity

发布于 2024-08-20 07:11:00 字数 704 浏览 7 评论 0原文

我是 Android 新手，我正在努力弄清楚我可以使用哪些工具。我现在正在针对 Android 2.0.1 进行开发，因为我的设备就是这样运行的。

具体来说，我正在编写一个应用程序，我想将图像上传到 Picasa 相册。我几乎可以肯定这是受支持的；例如，内置（Google？）照片查看器有一个带有 Picasa 选项的“共享”按钮，甚至还有一小部分示例代码，包括片段

[借用的代码！如果这违反了规则，我深表歉意..]

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

这看起来正是我想要的。

但我在任何地方都找不到任何文档。事实上我很不清楚如何使用这种类型的资源。在 Eclipse 中，我是否需要包含另一个项目 com.google.android.apps.uploader？如果是这样，我该如何获取它？我该如何包含它？有没有提供工作示例代码供我查看？

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.

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

[borrowed code! apologies if this is against the rules..]

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

which looks like exactly what I want.

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?
