O caminho das pedras do HTML5

Um dos desafios de desenvolver utilizando o HTML5 é saber escolher com precisão as APIs nativas que se pretende utilizar. Digo que é um desafio, pois por não ser uma especificação ainda finalizada, a implementação das APIs nativas do HTML5 não é tão consistente como se imagina entre diversos navegadores. Existem áreas específicas, como suporte básico a Canvas ou o Local Storage, que já são amplamente suportadas de modo uniforme entre os navegadores, mas em outras áreas, como Web Audio e IndexedDB, a implementação não é ainda regular - mas tende a ser em breve.

Android SDK 的一个bug ------ parameters.getFocusDistances 无法使用(被拍摄物体和摄像头之间的距离无法测量)

这是很早之前我发现的一个问题,当时想利用“焦距”来定位被拍摄物体和手机摄像头之间的距离,注意不是摄像头预览画面里两个点之间的距离,这是个平面距离。本文所说的距离是垂直距离。最终失败,原因是parameters.getFocusDistances返回的值永远是inifinte。手机型号是华为U9200.

下面是测试核心代码:

<SPAN style="FONT-SIZE: 18px">@Override

    public void onAutoFocus(boolean success, Camera camera) {

        //READ FOCUS DISTANCES HERE

        Camera.Parameters parameters = camera.getParameters();

        float[] distances = new float[3];

        if (success) {

Digital Mementos Developer's Guide

Digital Mementos is an Intel® Cloud Services Platform sample application that enables users to plan a trip, find points of interest (POI) in the region, and keep a trip journal. During the trip, users can get helpful information about POI, such as a description of the location, hours of operation, and a map. They can also post check ins and leave geo messages. Digital Mementos provides cross-platform, transparent consumer experiences in the form of Windows* 8, Android*, and web client applications.

Digital Mementos consists of the following components:

  • Android*
  • Microsoft Windows* 8
  • Cloud Services
  • Introducing the Digital Mementos Sample Application

    Digital Mementos is a sample travel application that uses three Intel® Cloud Services Platform services, namely Intel® Identity Services, Location Based Services, and Context Services, to build true cross-platform, transparent consumer experiences in the form of Windows* 8, Android*, and web client applications. Digital Mementos is a device agnostic, context-aware concept that provides a seamless, integrated user experience by taking advantage of the corresponding features of the devices where the features are running.

    主要是mvc架构,

    M层为数据层,两个用途:1保存数据;2发送数据更新信息;

    V层为视图层,两个用途:1接受用户从界面上的操作;2根据M层的数据显示相应的界面;

    C层为控制层,两个用途:1处理和界面无关的代码逻辑;2接受和处理网络数据;

    继续……

    按照自己的经验,游戏中的mvc架构有两种思想,1,以mvc架构为主,整个框架就是一个mvc架构;2,以对象思想为主,对象中使用mvc架构,整个框架使用一个平行结构。先看看使用mvc架构的方式,如下图:

    各个模块分为mvc三部分

    ,有些模块可能只有其中一部分,比如只有view,只有model等。不同模块的mvc三部分对于其他模块也是可见的,比 如bagview可以访问rolectrl,也许不需要访问,这里只是举例说明,rolectrl对于bagview是可见的。

    整个框架的运行流程如下:

    Использование библиотеки масштабируемой векторной графики в Android на базе архитектуры Intel

    Формат масштабируемой векторной графики (Scalable Vector Graphics, SVG) — это семейство спецификаций на базе XML, предназначенных для хранения двумерной статической и динамической (интерактивной или анимированной) векторной графики, а также текста или встроенных растровых изображений. Спецификация SVG является полностью открытым межплатформенным стандартом и разрабатывается консорциумом W3C с 1999 г.
