Android SDK (Softeare Development Kit) & Golden Rules of Performance

Android SDK (Software Development Kit)&Golden Rules of Performance:

Welcome to Android Design, your place for learning how to design exceptional Android apps. 





Any one can develop ANDROID App's .For that i provide the guidence to you .
Before start development just think about some topics......... 
1) Which way you want to develop application ?
2) Do you want your application performance will be high.. For that what we do?
3) While creating application what standards are we follow?
4) What process we need to accomplish your task effectively and faster?
6) Where we comfortably built a application? 
7) In future generation what type of interface they will Expected?
        Etc...................?!  So we need to know the
Note: This beginners guide will helps to know what basic standards follow to built a application. If you know all of those things again re-verify all of that.

Application development kit:

Get the Android SDK

Note: First you must be install the JAVA plugin to your computer.

Java Platform (JDK) 7u25

The Android SDK provides you the API libraries and developer tools necessary to build, test, and debug apps for Android.

 

Download the SDK
ADT Bundle for Windows

Getting Started with Android Studio

EARLY ACCESS PREVIEW

Download Android Studio v0.2.x
for Windows

This download includes:

• Android Studio early access preview
• All the Android SDK Tools to design, test, debug, and profile your app
• The latest Android platform to compile your app
• The latest Android system image to run your app in the emulator

Android Studio is a new Android development environment based on IntelliJ IDEA. Similar to Eclipse with the ADT Plugin, Android Studio provides integrated Android developer tools for development and debugging. On top of the capabilities you expect from IntelliJ, Android Studio offers:

• Gradle-based build support.
• Android-specific refactoring and quick fixes.
• Lint tools to catch performance, usability, version compatibility and other problems.
• ProGuard and app-signing capabilities.
• Template-based wizards to create common Android designs and components.
• A rich layout editor that allows you to drag-and-drop UI components, preview layouts on multiple screen configurations, and much more.

Caution: Android Studio is currently available as anearly access preview. Several features are either incomplete or not yet implemented and you may encounter bugs. If you are not comfortable using an unfinished product, you may want to instead download (or continue to use) the ADT Bundle(Eclipse with the ADT Plugin).

Android NDK

The NDK is a toolset that allows you to implement parts of your app using native-code languages such as C and C++. For certain types of apps, this can be helpful so you can reuse existing code libraries written in these languages, but most apps do not need the Android NDK.

Before downloading the NDK, you should understand that the NDK will not benefit most apps. As a developer, you need to balance its benefits against its drawbacks. Notably, using native code on Android generally does not result in a noticable performance improvement, but it always increases your app complexity. In general, you should only use the NDK if it is essential to your app—never because you simply prefer to program in C/C++.

Typical good candidates for the NDK are self-contained, CPU-intensive operations that don't allocate much memory, such as signal processing, physics simulation, and so on. When examining whether or not you should develop in native code, think about your requirements and see if the Android framework APIs provide the functionality that you need.

Google Ideas

Google Ideas is a think/do tank that explores how technology can enable people to confront threats in the face of conflict, instability or repression. We connect users, experts and engineers to research and seed new technology-driven initiatives.

Google Ideas was founded on the principle that the next five billion to come online will face far greater human challenges than the first two billion. Many of these challenges are thorny and difficult to address, and include violent extremism and fragile states, among others.

Through events online and offline, we bring people with a diverse range of expertise and experience together. At our summits we convene people around a range of specific issues and use ‘labs’ — working breakout groups — to accelerate project development with strategic partners.

We find new ways that connected technologies can offer solutions to people caught in these circumstances, use research to provide fresh insights and develop interactive data visualizations to bring information to life. Wherever possible we make the source code of our projects available for use by others under an open-source license.

Events

Through gatherings large and small, offline and online, Google Ideas brings experts, technologists and people with relevant experience together from across a wide range of disciplines and backgrounds to reframe how technology can enable people to confront threats in the face of conflict, instability or repression.

By convening those with real experience with experts and technologists, technology initiatives are seeded and partnerships often formed. At our summits, we convene a large number of diverse attendees; from academics to government representatives, nonprofits to private sector organizations, filmmakers to those with personal experience.

Participate in the conversations through our regular G+ hangouts, or watch videos from previous events.

A faster Internet — designed by computers?

 

TCP, the transmission control protocol, is one of the core protocols governing the Internet: If counted as a computer program, it’s the most widely used program in the world.

One of TCP’s main functions is to prevent network congestion by regulating the rate at which computers send data. In the last 25 years, engineers have made steady improvements to TCP’s congestion-control algorithms, resulting in several competing versions of the protocol: Many Windows computers, for instance, run a version called Compound TCP, while Linux machines run a version called TCP Cubic.

At the annual conference of the Association for Computing Machinery’s Special Interest Group on Data Communication this summer, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory and Center for Wireless Networks and Mobile Computing will present a computer system, dubbed Remy, that automatically generates TCP congestion-control algorithms. In the researchers’ simulations, algorithms produced by Remy significantly outperformed algorithms devised by human engineers.

“I think people can think about what happens to one or two connections in a network and design around that,” says Hari Balakrishnan, the Fujitsu Professor in Electrical Engineering and Computer Science, who co-authored the new paper with graduate student Keith Winstein. “When you have even a handful of connections, or more, and a slightly more complicated network, where the workload is not a constant — a single file being sent, or 10 files being sent — that’s very hard for human beings to reason about. And computers seem to be a lot better about navigating that search space.”

Lay of the land

Remy is a machine-learning system, meaning that it arrives at its output by trying lots of different possibilities, and exploring further variations on those that seem to work best. Users specify certain characteristics of the network, such as whether the bandwidth across links fluctuates or the number of users changes, and by how much. They also provide a “traffic profile” that might describe, say, the percentage of users who are browsing static Web pages or using high-bandwidth applications like videoconferencing.

Finally, the user also specifies the metrics to be used to evaluate network performance. Standard metrics include throughput, which indicates the total amount of data that can be moved through the network in a fixed amount of time, and delay, which indicates the average amount of time it takes one packet of information to travel from sender to receiver. The user can also assign metrics different weights — say, reducing delay is important, but only one-third as important as increasing throughput.

Remy needs to test each candidate algorithm’s performance under a wide range of network conditions, which could have been a prohibitively time-consuming task. But Winstein and Balakrishnan developed a clever algorithm that can concentrate Remy’s analyses on cases in which small variations in network conditions produce large variations in performance, while spending much less time on cases where network behavior is more predictable.

They also designed Remy to evaluate possible indicators of network congestion that human engineers have not considered. Typically, TCP congestion-control algorithms look at two main factors: whether individual data packets arrive at their intended destination and, if they do, how long it takes for acknowledgments to arrive. But as it turns out, the ratio between the rates at which packets are sent and received is a rich signal that can dictate a wide range of different behaviors on the sending computer’s end.

Down to cases

Indeed, where a typical TCP congestion-control algorithm might consist of a handful of rules — if the percentage of dropped packets crosses some threshold, cut the transmission rate in half — the algorithms that Remy produces can have more than 150 distinct rules.

“It doesn’t resemble anything in the 30-year history of TCP,” Winstein says. “Traditionally, TCP has relatively simple endpoint rules but complex behavior when you actually use it. With Remy, the opposite is true. We think that’s better, because computers are good at dealing with complexity. It’s the behavior you want to be simple.” Why the algorithms Remy produces work as well as they do is one of the topics the researchers hope to explore going forward.

In the meantime, however, there’s little arguing with the results. Balakrishnan and Winstein tested Remy’s algorithms on a simulation system called the ns-2, which is standard in the field.

In tests that simulated a high-speed, wired network with consistent transmission rates across physical links, Remy’s algorithms roughly doubled network throughput when compared to Compound TCP and TCP Cubic, while reducing delay by two-thirds. In another set of tests, which simulated Verizon’s cellular data network, the gains were smaller but still significant: a 20 to 30 percent improvement in throughput, and a 25 to 40 percent reduction in delay.

“I am thrilled by the approach,” says Victor Bahl, research manager of the Mobility and Networking Group at Microsoft Research. “When you can constrain the problem domain and define precisely what you want out of the protocol, I can believe that their system is better than a human.”

Bahl cautions that “when the protocol has to do many things for many people or many devices, then it’s not clear whether this is the optimal method.” But he adds that it could very well be that, in the future, networked computers will adopt different congestion-control policies depending on the types of applications they’re running. “I could see that that’s where this thing would excel,” he says.

LIMBO PC GAME FOR (WINDOWS..........)

Over View

Limbo is a platform game made by developerPlaydead in Copenhagen, Denmark, with heavy emphasis on ambience. The game is entirely monochromatic, with nothing more than black and white and shades of grey filling the world. There is no map, no HUD, no dialogue or descriptions - indeed, the only word that appears outside of menus at all is the word "Hotel" which appears on two signs. There is also very little music throughout the game, with it only being heard in specific locations and maintaining the minimalist approach in its composition. The game also contains no loading screens, and can be played continuously from start to finish without pause. It was released on July 21st, 2010, the first game to appear on Xbox Live's Summer of Arcade 2010.

The story in Limbo is never properly detailed in the game. The only written source of the game's story can be found on the internet. "Uncertain of his sister's fate, a young boy enters Limbo..." This is never stated in the game itself, and players are left to interpret the narrative for themselves.
