Best option for using the GData APIs on Android?
提问by nyenyec
What's the least painful and most size efficient way to use the Google Data APIs in an Android application?
在 Android 应用程序中使用 Google 数据 API 的最不痛苦和最有效的方法是什么？
After a few quick searches t seems that there is an android-gdataproject on Google Code that seems to be the work of a single author. I didn't find any documentation for it and don't even know if it's production ready yet.
经过几次快速搜索后，似乎 Google Code 上有一个android-gdata项目，似乎是一个作者的作品。我没有找到它的任何文档，甚至不知道它是否已经准备好生产。
An older option, the com.google.wireless.gdata package seems to have been removedfrom the SDK. It's still availablein the GIT repository.
较旧的选项 com.google.wireless.gdata 包似乎已从SDK 中删除。它仍然在 GIT 存储库中可用。
Before I invest too much time with either approach I'd like to know which is the best supported and least painful.
在我为这两种方法投入太多时间之前，我想知道哪种方法得到最好的支持和最少的痛苦。

Please take a look at the Google API Client Libraryfor Java which supports Android
请查看支持 Android的Google API Client Libraryfor Java
It also supports new GDatatechnologies like the recently announced partial response/update and JSON-C, both of which can be a dramatic improvement in efficiency on Android.
它还支持新的GData技术，如最近宣布的部分响应/更新和JSON-C，这两种技术都可以显着提高 Android 上的效率。
To start, please take a look at the Android Developer's Guide. Also, please look at the Android sample for Picasa Web Albums Data API, which demonstrates the ability create/update/delete a photo album and to upload a picture.
首先，请查看Android 开发人员指南。另外，请查看Picasa 网络相册数据 API的Android 示例，它演示了创建/更新/删除相册和上传图片的能力。

I also looked at the google-code project and the git repo. I steered away from the google-code project due to the apparent baggage that came along in required projects. I ended up creating custom implementations as necessary to adapt the standard java API. You can find a rough description of my solution in the android-developers group. It is 4 short, easily tested classes
我还查看了 google-code 项目和 git repo。由于所需项目中的明显包袱，我避开了 google-code 项目。我最终根据需要创建了自定义实现以适应标准的 Java API。您可以在android-developers 组中找到对我的解决方案的粗略描述。它是 4 个简短的、易于测试的课程

DocumentListFeed feed = client.getFeed(feedUri, DocumentListFeed.class);
TextView textView = (TextView) findViewById(R.id.textview);
String text = "";
for (DocumentListEntry entry : feed.getEntries())
{
text += entry.getTitle().getPlainText() + "\r\n";
}
textView.setText(text);
