want to access google books from android app

I am pretty new to android; I would like to access google books from my android app. Can anyone provide any pointers, sample code开发者_JS百科, or advice on how to get going here?

Thanks!

Well, you probably know about the Books Data API. Since there are no samples for using google-api-java-client with that API yet (although you can add one and get all your friends to 'star' it so that Google pay attention to it), your basic strategy is:

1. download the samples using Mercurial and Maven into your favourite IDE (such as IntelliJ ;- ) It's worth learning Maven/Mercurial or at least how to set them up for your IDE)
2. look particularly at the calendar-v2-atom-android-sample
3. create some 'model' classes with @Key annotations which mirror the structure of the elements you'll get in the feed using the samples as a guide for how to use them

There unfortunately is no shortcut for coming to terms with the elements of the ATOM 'feed'.

Handy things to know

These include:

1. 'everything is an <entry/>
2. transport.buildGetRequest().execute().parseAs(MyModel.class) handles your basic needs
3. the @Key annotation can handle any namespace prefixes that you gave to your parser when you set it up (xref lines 96-102 of CalendarAndroidSample.java where it sets up the transport and parsers)

Sorry about all the links, but that's what Google development is like!

It's best to think of the google-api-java-client as a tool that helps you with all the ugly XML and HTTP plumbing, so that you can build your own api. It's a bit of work, but once you've mastered the GoogleUrl class (just read the source of it and GenericUrl), and the @Key annotations, there isn't actually a lot of boring work. You get down to tin tacs of 'what do I want to actually do with this information' surprisingly quickly.
