Picasa Web Service in android

Is it possible to get Picasa Album photos using gdata API ( Google Data API)

my imports :

   "import com.google.gdata.client.photos.PicasawebService;
    import com.google.gdat开发者_如何学Ca.data.photos.AlbumFeed;
    import com.google.gdata.data.photos.PhotoEntry;"

my service creation :

PicasawebService service = new PicasawebService("exampleClient");

If I use that in my Android activity it compiles fine when I run the app I get no class found excetion. Any Help will be greatly appreciated

Your GData client JAR should be be in the war/WEB-INF/lib directory

From the documentation:

To use this library in your App Engine application, you must first copy the JARs listed below from the lib directory of the gdata-java-client package to your project's war/WEB-INF/lib directory:

gdata-client-1.0.jar
gdata-client-meta-1.0.jar
gdata-core-1.0.jar
gdata-docs-3.0.jar
gdata-docs-meta-3.0.jar
