Cómo desarrollar y evaluar aplicaciones Android* de 64 bits en plataformas x86 Intel®

Introducción

Cada vez hay más dispositivos móviles para el público en general que cuentan con arquitectura de 64 bits. Utilizar Android* de 64 bits es una excelente manera de acceder al mercado. En este artículo se presentará Android en arquitectura Intel® de 64 bits y se analizarán sus compatibilidades particulares, detalles técnicos, mejoras de rendimiento, problemas y soluciones disponibles para Android en plataformas basadas en procesadores Intel® Atom™.

  • Query regarding development of User-based Media SDK plugins

    Hello All, 

    This is Rishab here, I am developing an encoder plugin for Intel Media SDK. I am able to get it up and running “mfxCreateEncoderPlugin()” API's and it works smoothly. I have created a class derived from MFXEncoderPlugin class for the same.

    Now I need to support linking my plugin using CreatePluginPtr_t() API's which is called when the user-based plugin is loaded through registry.

    1. I would like to know the exact functionality of this API's.

    物联网开发套件中Yocto软件版本的一些提示——样例:添加Java JRE

    近来一些人问我要更多Yocto软件版本的文档。尤其是一位在将Java添加到自己的物联网Yocto软件版本时遇到困难的创客。与他的对话引发了下面的帖子:

    为什么你不需要自己的Yocto软件版本

    首先:通常情况下使用物联网开发套件时你不必接触Yocto软件版本。开发套件提供了一个事先编译好的SD卡启动镜像放入你的英特尔(R) Galileo开发板。然后你就可以着手开发了。另外还存在一个软件包集合,你能够从中安装更多的软件包到你的镜像,譬如在添加了下面几行代码:

    
    	# cat >> /etc/opkg/iotdk.conf <<EOF
    
    	src/gz all http://iotdk.intel.com/ipk/all
    
    	src/gz i586 http://iotdk.intel.com/ipk/i586
    
    	src/gz clanton http://iotdk.intel.com/ipk/clanton
    
    	EOF
    
    	

    Screen_Capture -> h264_Encoder

    Hello.
    Please can you help me.
    Please show me or send me some examples, source code of how to make Screen_Capture -> h264_Encoder.

    I understand from pseudo-code how make it, but how implement it in real code? I tried study examples of Intel Media SDK, but theirs code is very difficult for understanding.

    How get Screen_Capture_Buffer and put this buffer to input of h264_Encoder. Please help me to learn it by your sample.

    Or may be you know more simple way for learning.

    Android开发规范示范——开发必学

    之前从在工作室接触工作项目开发至今,由于需要协同队友一起进行项目开发,规范编程是协同开发的基础。有时队友A写了一个类或者修改了某个类的一些成员属性或者方法,如果按照其惯有的编程风格,编写出来的代码别人也看不懂。这里拿本人开发过程中的规范实例,仅供参考。

    工具及开放环境

    开发工具统一使用eclispe集成Android SDK作为开发工具,工作区的编码格式使用UTF-8,ADT实时更新最新本。

    Java版本统一使用JDK版本为1.7。

    命名规范

    包(package):采用完整的英文描述符,由小写字母组成;对于全局包,将Internet域名反转换上包名

    例如:

    表示包下所有类只用来存放常量

    com.gdut.topview.constant 

    表示包下所有类只用来存放自定义控件

    Gesture Control and the Next Wave of 3D Cameras

    Within the last five years, the field of Natural User Interfaces (NUIs) has been revolutionized by the influx of new devices onto the market. These devices allow users to interact directly with a user interface using gestures or speech, for example. This article looks at the extent to which this type of control is both intuitive and comfortable.

    Gestensteuerung und die nächste Welle der 3D-Kameras

    Innerhalb der letzten fünf Jahre gab es auf dem Gebiet der Natural User Interfaces (NUI) eine regelrechte Revolution, da eine Vielzahl neuer Geräte auf den Markt kam. Sie ermöglichen dem Nutzer z.B. durch Gesten oder Sprache eine direkte Interaktion mit einer Benutzeroberfläche. Doch inwieweit ist diese Art der Steuerung sowohl intuitiv als auch komfortabel?

    How to control microphone (mute) input volume (input gain)

    I'm using Intel INDE for video streaming purposes (Android).

    The main problem is how to mute/unmute the devices microphone in Android.

    The only way I found is to not set the AudioFormatAndroid of Intel INDE API deleting these lines:

    audioFormat = new AudioFormatAndroid("audio/mp4a-latm", 44100, 1);
    capture.setTargetAudioFormat(audioFormat);

    The problem is that I need to do it during the streaming, not before.

    Therefore I tried to manage microphone input settings like:

    Intel® RealSense™ SDK Gold R2 – An Overview

    The Intel® RealSense™ SDK Gold R2 (v4.0) release is now available! This brief overview walks you through product improvements from Gold R1 (v3.1) and some of the new natural interaction modalities that can be used to create compelling applications using the Intel RealSense SDK.

  • Developing / Debugging Android apps on the Dell Venue 8-7000

    I just got my hands on a the Venue 8-7000 and I was a little surprised to discover there weren't any development drivers available for Windows 8.x.

    After some digging/experimenting I managed to get it working.  It required getting the hardware IDs via the device manager and manually adding the fields to the Google USB Drivers.
