Compilation What is Dalvik ? ● Android’s Virtual Machine ● Designed to run on embedded systems ● Register-based (lower memory consumption) ● Run Dalvik Executable (.dex) files What is ART ? ● Android RunTime ● Dalvik’s successor ● ART Is Not a JVM ● Huge performance gain thanks to ahead-of-time (AOT) compilation ● Available in Android 4.4 What is ART ? Executable files Dalvik: .dex files ● Not the same bytecode as classical Java bytecode ● .class files are converted in .dex files at build time ● Optimized for minimal memory footprint Dalvik: .dex files Dalvik: application installation ● Verification: ○ bytecode check (illegal instructions, valid indices,...) ○ checksum on files ● Optimization: ○ method inlining ○ byte swapping and padding ○ static linking ART: OAT file ● Generated during installation (dex2oat) ● ELF format ● Classes metadata Memory management Zygote ● Daemon started at boot time ● Loads and initializes core libraries ● Forks to create new Dalvik instance ● Startup time of new VM is reduced ● Memory layouts are shared across processes Dalvik: memory management ● Memory is garbage collected ● Automatic management avoids programming errors ● Objects are not freed as soon as they become unused Dalvik: memory allocation ● Allocation profiling: ○ allocation count (succeeded or failed) ○ total allocated size (succeeded or failed) ● malloc -

PDF a Parent and Carer's Guide to Google Safesearch and Youtube Safety Mode
A parent and carer’s guide to Google SafeSearch and YouTube Safety Mode Google is the most used search engine in the world and users can type in a word, expression, phrase or sentence in more than 100 languages and receive instant results in text, images or videos. YouTube is ranked as the world second largest search engine, with over 1 billion users that each day watch a billion hours of videos. With limited ways to control content, the Google and YouTube platforms can be challenge for parents and carers because there are hundreds of thousands of videos, images and other content that may not be considered appropriate for children or young people. This article explains why it may be useful to filter search results on Google and YouTube and how parents and carers can engage safety settings on these two platforms. Please note – the weblinks in this document are only available in English language. Is Google content appropriate for children and young people? A Google query lasts less than half a second, however there are many more steps involved before a final result is provided. This video from Google illustrates exactly how a Google search works. When Google realized that the results of an unfiltered Google search contained content that is not always appropriate for children, Google then developed SafeSearch so that children could safely find documents, images, and videos within the Google database. Is YouTube content appropriate for children and young people? Google purchased YouTube in 2006 with the idea that YouTube would provide a marketing hub as more viewers and advertisers chose the Internet over television. -

Initially developed by Android, Inc., which Google backed financially Android (operating system) 2 and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance: a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The first publicly available smartphone running Android, the HTC Dream, was released on October 22, 2008. The user interface of Android is based on direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching and reverse pinching to manipulate on-screen objects. Internal hardware such as accelerometers, gyroscopes and proximity sensors are used by some applications to respond to additional user actions, for example adjusting the screen from portrait to landscape depending on how the device is oriented.
