and my code is:

GoogleAccountCredential credential;
Calendar client;
JsonFactory jsonFactory = GsonFactory.getDefaultInstance();
HttpTransport transport = AndroidHttp.newCompatibleTransport();
    credential =
        GoogleAccountCredential.usingOAuth2(this, Collections.singleton(CalendarScopes.CALENDAR));
    SharedPreferences settings = getPreferences(Context.MODE_PRIVATE);
    credential.setSelectedAccountName(settings.getString(PREF_ACCOUNT_NAME, null));
    // Calendar client
    client = new com.google.api.services.calendar.Calendar.Builder(
        transport, jsonFactory, credential).setApplicationName("Google-CalendarAndroidSample/1.0")
        .build();

If you already included google http client android jar into your Android project, then you just do the following steps in your Eclipse environment.

  1. Right click on your project in the project’s panel.
  2. Select “Properties” option.
  3. In the Properties window, Click on “Java Build Path”.
  4. In the right side of that window, select “Libraries” tab.
  5. Click on “Add External JARs” button and add this library where you have saved previously.
  6. Now click on “Order and Export” tab and check on “JarName.jar” Click on “Ok”.
