    Android and android phones Android and android phones Presentation Transcript

    •  Android is a Linux-based operating system for mobile devices such as smartphones and tablet computers, developed by Google in conjunction with the Open Handset Alliance. Android was initially developed by Android Inc, whom Google financially backed and later purchased in 2005 The unveiling of the Android distribution in 2007 was announced with the founding of the Open Handset Alliance, a consortium of 86 hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. Google releases the Android code as open-source, under the Apache License. The Android Open Source Project(AOSP) is tasked with the maintenance and further development of Android.
    •  Android has a large community of developers writing applications ("apps") that extend the functionality of the devices. Developers write primarily in a customized version of Java, and apps can be downloaded from online stores such as Google Play (formerly Android Market), the app store run by Google, or third-party sites. In June 2012, there were more than 600,000 apps available for Android, and the estimated number of applications downloaded from Google Play was 20 billion.
    •  Android became the world’s leading smartphone platform at the end of 2010. For the first quarter of 2012, Android had a 59% smartphone market share worldwide.At the half of 2012, there were 400 million devices activated and 1 million activations per day.
    •  Handset layouts The platform is adaptable to larger, VGA, 2D graphics library, 3D graphics library based on OpenGL ES 2.0 specifications, and traditional smartphone layouts. Storage SQ Lite, a lightweight relational database, is used for data storage purposes. ConnectivityAndroid supports connectivity technologies including GSM/EDGE, IDEN, CDMA, EV- DO, UMTS, Bluetooth, Wi-Fi, LTE, NFC and WiMAX.
    •  Connectivity Android supports connectivity technologies including GSM/EDGE, IDEN, CDMA, EV- DO, UMTS, Bluetooth, Wi-Fi, LTE, NFC and WiMAX. Multiple Language Support - Android supports multiple languages . Web browser- The web browser available in Android is based on the open-source WebKit layout engine, coupled with Chromes V8 JavaScript engine. The browser scores 100/100 on the Acid3 test on Android 4.0.
    •  Streaming media support RTP/RTSP streaming (3GPP PSS, ISMA), HTML progressive download (HTML5 <video> tag). Adobe Flash Streaming (RTMP) and HTTP Dynamic Streaming are supported by the Flash plugin Apple HTTP Live Streaming is supported by RealPlayer for Android, and by the operating system in Android 3.0 (Honeycomb).
    •  Java support While 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 support -Android supports the following audio/video/still media formats: WebM, H.263, H.264 (in 3GP or MP4 container), MPEG-4 SP, AMR, AMR-WB (in 3GP container), AAC, HE-AAC (in MP4 or 3GP container),MP3, MIDI, Ogg Vorbis, FLAC, WAV, JPEG, PNG,GIF, BMP, WebP.
    •  Additional hardware support -Android can use video/still cameras, touchscreens, GPS, accelerometers, gyroscop es, 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.
    •  Multitasking of applications, with unique handling of memory allocation, is available Voice based features – Google search through voice has been available since initial release. Voice actions for calling, texting, navigation, etc. are supported on Android 2.2 onwards. Tethering Android 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 capture -Android supports capturing a screenshot by pressing the power and volume-down buttons at the same time. 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 developers tool). These alternative methods are still available with the latest Android.
    •  External storage -Most 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 as USB 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.
    •  1. Samsung Galaxy S3 Probably the best smartphone the world has ever seen. The Samsung Galaxy S3 has a giant 4.8-inch display which offers up a brilliant picture regardless of viewing angle or light condition. The phone runs Android 4.0 ICS, with Samsung’s own TouchWiz UI for added user experience. There is an 8-MP camera with an array of features and an impressive 1.4GHz quad- core processor with 1GB RAM for superior performance. A truly awesome phone.
