Question

I am trying to use the Google generated API library for the first time for Android. I have taken code from the the Sample Program provided by Google. My code looks like

Answer 1

May be a bit late for this one, but the the jar that you're looking for is google-http-client-1.5.0-beta.jar

This jar defines com.google.api.client.http.* and com.google.api.client.json.*

Answer 2

Here is a list of the libraries you should have in you project: http://code.google.com/p/google-api-java-client/wiki/Setup

Answer 3

You must explicit add library reference of google-http-client-1.5.0-beta.jar(right click project->Properties->Java Build Path->Add External JARs), don't believe class path. If you do not do this, in the apk file does not contain the required data。
You can download Google plus library from here google-plus-java-starter_v5.zip

Answer 4

plus = Plus.builder(transport, jsonFactory).setApplicationName("Google-PlusSample/1.0")
    .setHttpRequestInitializer(accessProtectedResource)
    .setJsonHttpRequestInitializer(new JsonHttpRequestInitializer() {
        @Override
        public void initialize(JsonHttpRequest request) {
            PlusRequest plusRequest = (PlusRequest) request;
            plusRequest.setPrettyPrint(true);
        }
    }).build();

use this instead of

Plus plus = new Plus(new NetHttpTransport(), new JacksonFactory());
