ApiUtils类：

/**

 */
public class ApiUtils {

    public static final String APP_NAME = BuildConfig.APP_NAME;
    public static final String WEB_CLIENT_ID = BuildConfig.WEBCLIENT_ID;
    public static final String AUDIENCE = "server:client_id:" + WEB_CLIENT_ID;
    /**
     * Class instance of the HTTP transport.
     */
    public static final HttpTransport HTTP_TRANSPORT = AndroidHttp.newCompatibleTransport();
    /**
     * Class instance of the JSON factory.
     */
    public static final JsonFactory JSON_FACTORY = new AndroidJsonFactory();

    private Context mContext;
    private String mAccountName;

    public ApiUtils(Context context, String accountName){
        this.mContext = context;
        this.mAccountName = accountName;
    }


    private GoogleAccountCredential getCredential(){
        GoogleAccountCredential credential = GoogleAccountCredential.usingAudience(mContext, AUDIENCE);
        credential.setSelectedAccountName(mAccountName);
        return credential;
    }


    /**
     * Retrieve a Sales api service handle to access the API.
     */
    public Sales getApiServiceHandle() {
        // Use a builder to help formulate the API request.
        Sales.Builder salesAPI = new Sales.Builder(HTTP_TRANSPORT, JSON_FACTORY, getCredential());
        Log.d("RootURL", salesAPI.getRootUrl());
        salesAPI.setApplicationName(APP_NAME);
        return salesAPI.build();
    }

    /**
     * @return Sales Api
     */
    public Sales.SalesAPI getApi(){
        return getApiServiceHandle().salesAPI();
    }
}
