Snapdragon S4 Thermal Comparison and Butter Benchmark

Today's high-end smartphones and tablets are capable of doing many intensive computing tasks, such as 3D gaming, shooting HD video, and editing photos. The more demanding these tasks, the harder the powerful processor works. That can result in excessive heat, which can result in lower performance and reliability issues. Over time, excessive heat can also be damaging to components, especially the battery. The hotter a device gets, the more it degrades battery capacity. To combat this, Snapdragon S4 processors are specially designed to keep their cool. Watch this video to see a Snapdragon thermal comparison and our new Butter Benchmark.

O'Reilly Android Cookbook, A Crowd-sourced Cookbook on Writing Great Android Apps

The web site http://androidcookbook.com/ is a community-written web site which has also been used to create an O'Reilly Cookbook, both about how to build great Android applications.

It is full of how-to information along with code snippets that illustrate the ideas presented. It features both how-to's that overlap with the official documentation, and material that goes beyond this to be more tutorial, more in-depth, or explaining "lessons from the trenches": what actually works to get the application functioning well. Unlike most books written by one, two or a few individuals, this one has input from dozens of contributors, who were all able to view and comment on each others' recipes before the book was published. The published version(s) include printed books, eBooks, and other uses. And long after the book was first published in 2012, this site will continue to exist - with a larger collection of recipes than will fit in the published book - and serve as an Android developer resource site long after.

Google USB Driver for Windows

I have just updated Windows 8 Release Preview. When I connect Galaxy Nexus, it can be recognized with Internal Storage, but cannot be recognized by ADB.

In order to use Galaxy Nexus to develop Android on Windows (also Windows 8), Google USB Driver for Windows is needed.

The Google USB driver is a downloadable component for the Android SDK, available from the SDK Manager. The driver is for Windows only and provides the necessary drivers for the following devices:

• ADP1 / T-Mobile G1*
• ADP2 / Google Ion / T-Mobile myTouch 3G*
• Verizon Droid*
• Nexus One
• Nexus S

* Or similar hardware on other carriers

All other devices require Windows drivers provided by the hardware manufacturer, as listed in the OEM USB Drivers document. The Galaxy Nexus driver is also distributed by Samsung (listed as model SCH-I515).

Details: Google USB Driver from Android Document.


Remark:
M.S. Lubis. provide a solution to Install USB driver Galaxy Nexus on Windows8.
