★ Session Summary ★
One of the important technical novelties introduced with the recent release of Android Lollipop is the replacement of Dalvik, the VM which was used to execute the bytecode produced from Java apps, with ART, a new Android Run-Time. One interesting aspect in this upgrade is that the use of Just-In-Time compilation was abandoned in favour of Ahead-Of-Time compilation. This delivers better performance [1], also leaving a good margin for future improvements. ART was designed to support multiple compilers. The compiler that shipped with Android Lollipop is called the “Quick Compiler”. This is simple, fast, and is derived from Dalvik’s JIT compiler. In 2014 our team at ARM worked in collaboration with Google to extend ART and its Quick Compiler to add support for 64-bit and for the A64 instruction set. These efforts culminated with the recent release of the Nexus 9 tablet, the first 64-bit Android product to hit the market. Despite Google’s intention of replacing the Quick Compiler with the so-called “Optimizing Compiler”, the job for the the Quick Compiler is not yet over. Indeed, the Quick Compiler will remain the only usable compiler in Android Lollipop. Therefore, all competing parties in the Android ecosystem have a huge interest in investigating and improving this component, which will very likely be one of the battlegrounds in the Android benchmark wars of 2015. This talk aims to give an unofficial overview of ART’s Quick compiler. It will first focus on the internal organisation of the compiler, adopting the point of view of a developer who is interested in understanding its limitations and strengths. The talk will then move to exploring the output produced by the compiler, discussing possible strategies for improving the generated code, while keeping in mind that this component may have a limited life-span, and that any long-term work would be better directed towards the Optimizing Compiler.

This presention make about the operating system of Android,it's a open source system which is made like as linex-kernel. It was developed by google and release on 3rd September,2008.there are many versions of this operating system and much features...
This document primarily covers micro-optimizations that can improve overall app performance when combined, but it's unlikely that these changes will result in dramatic performance effects. Choosing the right algorithms and data structures should always be your priority, but is outside the scope of this document. You should use the tips in this document as general coding practices that you can incorporate into your habits for general code efficiency.
One of the trickiest problems you'll face when micro-optimizing an Android app is that your app is certain to be running on multiple types of hardware. Different versions of the VM running on different processors running at different speeds. It's not even generally the case that you can simply say "device X is a factor F faster/slower than device Y", and scale your results from one device to others. In particular, measurement on the emulator tells you very little about performance on any device.
To ensure your app performs well across a wide variety of devices, ensure your code is efficient at all levels and aggressively optimize your performance.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. Introduction
•Android is an open-source platform developed by
Google on 5th Nov. 2007 that's currently available on a
wide variety of smart phones. Android is a software stack
for mobile devices that includes an operating
system, middleware and key applications.
•Android is an open source operating system so almost
anyone can modify and tweak various components of it
thus it makes Android the most favored mobile operating
system.
•Android OS is developed on Linux platform which is
wholly dedicated to open source and so does Android.
6. Dalvik runtime (current VM)
•In standard Java environments, Java source code is
compiled into Java bytecode, which is stored within .class
files, the .class files are read by the JVM at runtime.
•Each class in your Java code will result in one .class file, this
means that if you have, say, one .java source file that
contains one public class, one static inner class, and three
anonymous classes, the compilation process (javac) will
output 5 .class files.
•On the Android platform, Java source code is still compiled
into .class files. But after .class files are generated, the “dx”
tool is used to convert the .class files into a .dex, or Dalvik
Executable, file.
Whereas a .class file contains only one class, a .dex file
contains multiple classes. It is the .dex file that is executed on
7. Working of Dalvik VM
•Android uses Dalvik and a Just-In-Time (JIT) compiler. This
means that Android apps are written in a generic version of
code, called bytecode, that is only half-compiled by
developers. Whenever the apps are launched, Dalvik
compiles the code “just in time” to run.
Fig:- Compiling steps in
8. Disadvantages of Dalvik
•As we have seen the working of the Dalvik VM’s working
as, “the Android apps are written in a generic version of
code, called bytecode, that is only half-compiled by
developers. Whenever the apps are launched, Dalvik
compiles the code “just in time” to run.”
•This means that whenever a new process (application) starts
it is compiled and loaded in the RAM to run the
application, when the application is removed from the RAM all
the compilation work of that bytecode needs to be done again
and again thus it is time consuming and significantly affects
the battery for all the unnecessary repeated processing
power.
9.
10. •Right after Android 4.4 was announced, Google
had partially implemented a new runtime compiler
in the software called ART that could potentially
replace Dalvik in the near future.
•Android RunTime, that compiles the bytecode when
applications are installed as opposed to compiling them just
before being launched. This is called Ahead-Of-Time (AOT)
compiling and is much, much more efficient on performance
and battery life.
•Dalvik was originally designed not for speed, smoothness, or
power, but to save space. Android devices at the time had
very limited storage and memory, and Google's primary
concern at the time was fitting everything into a small
footprint.
11. •Today, Android runs on much different hardware with tons of
power and storage, and Android could see a big performance
and battery improvement with a more modern runtime. That
new runtime is called "Android RunTime," and it's a
newer, speedier replacement for Dalvik.
•The Dalvik cache contains compiled bytecode, which still
needs to run in the dalvik virtual machine. This is faster than
running Java without JIT, but still much slower than native
code.
•ART compiles Java to native machine language, eliminating
the need to spin up a vm for each new app and to interpret
byte code.
12. •It’s not without downsides, though. ART
compiled code would take up slightly more room
on a device compared to apps that were only
compiled in use.
•But for most devices, the tradeoff is well worth it, installing
apps will also likely take longer using ART. Since they’re
compiled on installation, on bigger apps that could definitely
draw out the process a bit, but for most people I feel like the
performance gains would be worth it.
• The new runtime is already capable of cutting execution
time in half for most applications. This means that long-
running, processor-intensive tasks will be able to finish
faster, allowing the system to idle more often and for longer.
Regular applications will also benefit from smoother
animations and more instantaneous responses to touch and
13. •ART will compile bytecode to native code ahead of time.
Native code will take up more space than bytecode. Every
app will use about 10-20% extra space compared to dalvik
version. It won't be multiple GB's though.
•The other likely notable drawback will come in the form of a
longer install time for apps - the side effect of performing the
AOT compilation.
•Thus it seems that it has some drawbacks on ART but it is
recently being developed and not been fully optimized to
operate and it is not selected by default on latest KitKat (4.4)
version on android.
Drawbacks of ART
14. Dalvik VS ART
•Dalvik has been the default runtime environment of Android
since its first public release. It has also been the primary
bottleneck of the OS because it uses JIT (just-in-time)
compilation, requiring apps to be compiled on the go before
running them, which can be quite taxing on performance as
well as battery life.
•ART (Android RunTime) is a replacement for Dalvik that
uses AOT (ahead of time) compilation, meaning your apps
are compiled to a ready-to-run state before you even launch
them, making the process of launching and using them much
faster and smoother. And since this would reduce their
compilation frequency significantly, you can expect to start
seeing better battery life.
17. Conclusion
•Overall, ART sounds like a pretty amazing project, one that I
hope to see as a regular part of Android sooner rather than
later. The improvements are likely to be pretty amazing while
the drawbacks should be virtually undetectable. It doesn’t
mean ART will become the default in official releases from
Google for some time as it needs further development.
