TRANSCRIPT
The Android operating system has grown from a small development project into one of the most widely used mobile operating systems that people use on a daily basis. It has had many stages in growth and development that has led into the technology that powers many smart phones and tablet PCs today. Different versions have been released and perfected since the original release in 2008. http://eglobiotraining.com/android
Founded by Andy Rubin and Rich Minor of Palo Alto teamed up with Chris White and Nick Spears who worked together to develop the software and associated technology to produce the highly efficient Android operating system. While there have been many different versions of this technology, it is important to realize that each version of the operating system has helped to develop the most efficient operating system that is best for the customer of that point in time.

For example, smart phone technology has advanced so much in the past four years alone, the operating system of Android needed to advance as well in order to meet the needs of customers and to be able to compete with other operating systems on the market such as that of the Apple iPhone or the Blackberry.http://eglobiotraining.com/android
Android OS Names While it was only released about four years ago, the
Android operating system has gone through several different names and versions before settling on the Android name that is commonly known today. Previous names include Cupcake, Honeycomb and Jelly Bean among many others. The Android company worked on developing this product since the company's inception in 2003 in Palo Alto, California.

ll with backgrounds in IT and web development as well as software technology, the four men worked on the software and continued to do so after the company was acquired by Google in 2005. Since Google had the financial means as well as the man power to develop the Android software technology to the maximum extent, this was a great move for the Android company and led to substantial advances in the Android operating system and the product's release in 2008.

The browser scores 100/100 on the Acid3 test on Android 4.0.Java supportWhile most Android applications are written in Java, there is no Java Virtual Machine in the platform and Java byte code is not executed. Java classes are compiled into Dalvik executables and run on Dalvik, a specialized virtual machine designed specifically for Android and optimized for battery-powered mobile devices with limited memory and CPU.J2ME support can be provided via third-party applications.Media supportAndroid supports the following audio/video/still media formats: WebM, H.263, H.264, AAC, HE-AAC (in 3GP or MP4 container), MPEG-4 SP, AMR, AMR-WB (in 3GP container), MP3, MIDI, Ogg Vorbis, FLAC, WAV, JPEG, PNG, GIF, BMP, WebP.

Apple HTTP Live Streaming is supported by RealPlayer for Android, and by the operating system in Android 3.0 (Honeycomb)Additional hardware supportAndroid can use video/still cameras, touchscreens, GPS, accelerometers, gyroscopes, barometers, magnetometers, dedicated gaming controls, proximity and pressure sensors, thermometers, accelerated 2D bit blits (with hardware orientation, scaling, pixel format conversion) and accelerated 3D graphics.Multi-touchAndroid has native support for multi-touch which was initially made available in handsets such as the HTC Hero. The feature was originally disabled at the kernel level (possibly to avoid infringing Apple's patents on touch-screen technology at the time). Google has since released an update for the Nexus One and the Motorola Droid which enables multi-touch natively.[9]

Video callingAndroid does not support native video calling, but some handsets have a customized version of the operating system that supports it, either via the UMTS network (like theSamsung Galaxy S) or over IP. Video calling through Google Talk is available in Android 2.3.4 and later. Gingerbread allows Nexus S to place Internet calls with a SIP account. This allows for enhanced VoIP dialing to other SIP accounts and even phone numbers. Skype 2.1 offers video calling in Android 2.3, including front camera support.

The ability to control hardware has not yet been implemented.TetheringAndroid supports tethering, which allows a phone to be used as a wireless/wired Wi-Fi hotspot. Before Android 2.2 this was supported by third-party applications or manufacturer customizations.Screen captureAndroid supports capturing a screenshot by pressing the power and volume-down buttons at the same time.[16] Prior to Android 4.0, the only methods of capturing a screenshot were through manufacturer and third-party customizations or otherwise by using a PC connection (DDMS developer's tool). These alternative methods are still available with the latest Android.External storageMost Android devices include microSD slot and can read microSD cards formatted with FAT32, Ext3 or Ext4 file system. To allow use of high-capacity storage media such asUSB flash drives and USB HDDs, many Android tablets also include USB 'A' receptacle. Storage formatted with FAT32 is handled by Linux Kernel VFAT driver, while 3rd party solutions are required to handle other popular file systems such as NTFS, HFS Plus and exFAT.
