   Punjab Group of Colleges M.Com, MSc.IT and ADP Campus SPRING   2019   Course Title: Mobile Application  Assignment No.01   Course Instructor: Prof. Ethesham ul haq  Section: MIT4  Program: MSc.IT  Date: 7 th  Apr, 2019  Student Name: Wali ahmed   Registration No : L4 F 17 MSCT 0012   Topic:   Different VERSIONS and KEY FEATURES of an Android OS    The version history of the  Android   mobile operating system   began with the public release of the Android beta on November 5, 2007. The first commercial version, Android 1.0, was released on September 23, 2008. Android is continually developed by Google and the Open Handset Alliance, and it has seen a number of  updates to its base operating system since the initial release. Version history by API level are: 1.   Android 1.0 (API 1) 2.   Android 1.1 (API 2) 3.   Android 1.5 Cupcake (API 3) 4.   Android 1.6 Donut (API 4) 5.   Android 2.0 Eclair (API 5) 6.   Android 2.0.1 Eclair (API 6) 7.   Android 2.1 Eclair (API 7) 8.   Android 2.2 Froyo (API 8) 9.   Android 2.3 Gingerbread (API 9) 10.   Android 2.3.3 Gingerbread (API 10) 11.   Android 3.0 Honeycomb (API 11) 12.   Android 3.1 Honeycomb (API 12) 13.   Android 3.2 Honeycomb (API 13) 14.   Android 4.0 Ice Cream Sandwich (API 14) 15.   Android 4.0.3 Ice Cream Sandwich (API 15) 16.   Android 4.1 Jelly Bean (API 16) 17.   Android 4.2 Jelly Bean (API 17) 18.   Android 4.3 Jelly Bean (API 18) 19.   Android 4.4 KitKat (API 19) 20.   Android 4.4W KitKat, with wearable extensions (API 20) 21.   Android 5.0 Lollipop (API 21) 22.   Android 5.1 Lollipop (API 22) 23.   Android 6.0 Marshmallow (API 23) 24.   Android 7.0 Nougat (API 24) 25.   Android 7.1 Nougat (API 25) 26.   Android 8.0 Oreo (API 26) 27.   Android 8.1 Oreo (API 27) 28.   Android 9.0 Pie (API 28) 29.   Android Q (API 29) This is a list of features in the Android operating system:  Basic features    Messaging SMS and MMS are available forms of messaging, including threaded text messaging and Android Cloud To Device Messaging (C2DM) and now enhanced version of C2DM,  Android Google Cloud Messaging (GCM) is also a part of Android Push Messaging services.    Auto Correction and Dictionary Android Operating System has an interesting feature called Auto Correction. When any word is misspelled, then Android recommends the meaningful and correct words matching the words that are available in Dictionary. Users can add, edit and remove words from Dictionary as per their wish .      Web browser The web browser available in Android is based on the open-source Blink (previously WebKit) layout engine, coupled with Chromium's V8 JavaScript engine. Then the WebKit-using Android Browser scored 100/100 on the Acid3 test on Android 4.0 ICS; the Blink-based browser currently has better standards support. The old web browser is variably known as 'Android Browser', 'AOSP  browser', 'stock browser', 'native browser', and 'default browser' (from the time it was always the default). Starting with Android 4.4 KitKat, Google has began licensing Google Chrome (a proprietary software) separately from Android, but usually bundled with (what most device vendors did). Since Android 5.0 Lollipop, the WebView browser that apps can use to display web content without leaving the app has been separated from the rest of the Android firmware in order to facilitate separate security updates by Google.    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. As of Android 4.1, Google has expanded Voice Actions with ability to talk back and read answers from Google's Knowledge Graph when queried with specific commands. The ability to control hardware has not yet been implemented.    Multi-touch Android has native support for  multi-touch which was initially made available in handsets such as the HTC Hero. The feature was srcinally 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.    Multitasking Multitasking of applications, with unique handling of memory allocation, is available.    Screen capture Android supports capturing a screenshot  by pressing the power and home-screen buttons at the same time. Prior to Android 4.0, the only methods of capturing a screenshot were through manufacturer and third-party customizations (apps), or otherwise by using a PC connection (DDMS developer's tool). These alternative methods are still available with the latest Android.     TV recording Android TV supports capturing video and replaying it.    Video calling Android 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 the Samsung Galaxy S) or over IP. Video calling through Google Talk is available in Android 2.3.4 (Gingerbread) 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. Users with the Google+ Android app can perform video chat with other Google+ users through Hangouts.     Multiple language support Android supports multiple languages.    Accessibility Built-in text-to-speech is provided by TalkBack   for people with low or no vision. Enhancements for people with hearing difficulties are available, as are other aids. Connectivity:    Connectivity Android supports connectivity technologies including GSM/EDGE, Bluetooth, LTE,  CDMA, EV-DO, UMTS, NFC, IDEN and WiMAX.     Bluetooth Supports voice dialing and sending contacts between phones, playing music, sending files (OPP), accessing the phone book (PBAP), A2DP and AVRCP. Keyboard, mouse and  joystick (HID) support is available in Android 3.1+, and in earlier versions through manufacturer customizations and third-party applications.    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 applicaions or manufacturer customizations Media:    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 since Android 3.0 (Honeycomb).
