Everything You Want to Know about Android 5 aka Android L | Android L Features

android-5-features-specifications-google-i-o-android-l-developer-preview

Android 5.0 “Android L release” 

Google has chosen the stage of ‘ I / O 2014 to unveil the first information on the “L release” , which is the next evolution of Android . The new version will almost certainly be marked by numbering  5.0  and will bring with it a long list of ‘firsts’, from the look. From the graphical point of view, the redesign of the interface is complete, thanks to the introduction of the Material Design . The future incarnation of the platform (available starting in the fall) will have the unenviable task of crossing the boundaries of the areas smartphones and tablets, to become a true ecosystem that can embrace televisions, cars and smartwatch, respectively, with projects Android TV,  Android and Android Car Wear.

Android-5-features-android-l-specifications

Over a billion active devices each month, 315 million smartphones sold in Q4 2013 alone, 20 billion text messages exchanged every day and 93 million selfie snapped in just 24 hours. These data would be enough to understand what was the sudden growth recorded by Android in recent years, with the operating system a past competitor to the second floor for iOS to dominate the mobile universe. The tablet industry has been literally swallowed up by the green robot, with the platform that today is present in over 60% of the models on the market.[adsenseyu7]

The time is therefore ripe to introduce what may be defined in all respects the most important development ever for the operating system. Google introduced her from the stage of ‘ event I / O 2014 in San Francisco scene, with a first look at “The release” that will most likely arrive on devices with a digital display Android 5.0 .

 

The name : “Android L” 

During the three hours of the opening keynote, Sundar Pichai and his colleagues have always made ​​reference to the new version of Android as “The release”  or sometimes simply called it “L”. Therefore no confirmation on what will be the full name, but the assumptions are not lacking. Of course it will be a title borrowed from the world of sweets, as already seen in the past with Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, Jelly Bean and KitKat .

There are those who think Lollipop, Lemonade or other Licorice. However, taking into account the partnership signed by Google with Nestlé last year (for the launch of KitKat), we can also evaluate the possibility Lemonhead . For those who were not aware, is a registered trademark of  Ferrara Candy Company , a company that since the 60 markets in the United States small candy lemon yellow.

A few hours of the first ad, however, a further hypothesis comes to light: Android 5.0 could have the nickname of ” Lemon Cake “, generously clue left by Google within various sample images.

Material Design : Android 5

Android-5-features-android-l-specificationsThe look of Android has remained virtually unchanged over the past two and a half years, or since the launch of version 4.0 Ice Cream Sandwich by the end of 2011 is therefore time for a complete makeover , that knows how to refresh the UI of the OS and at the same time maintaining unchanged the immediacy and ease of use. The watchword is to Material Design .Google said the guidelines for everything related to the interface: from the buttons to the transitions, effects shown when you tap the display font. Nothing is left to chance. It is the step that follows the introduction of Polymer occurred on the occasion of the I / O 2013 Every single screen of the app will be studied by developers to adapt perfectly to any type of device, so responsive, i.e. regardless of the diagonal of the display. 

This will allow for example to have the same layout on smartphones and tablets, as well as on the TV with Android TV and in the passenger compartment of the car with Android Car . Below is a gallery useful to understand what changes in visual terms.

Farewell Dalvik Welcome ART : Android L

The “L release” of Android runtime system changes, replacing Dalvik with the new ART . In practical terms, this will translate into improved performance. It is perhaps the most awaited news from the developers, which in this way will be able to fully exploit the hardware capabilities provided by processors and graphics chips, optimizing the application code. 

Even gaming enthusiasts will welcome with open arms the rotation enough to think that the new technology will bring on smartphones and tablets advanced graphical effects comparable to those of console gaming. To this end, Google said it is working with chipmakers like NVIDIA, Qualcomm, ARM and Imagination Technologies.

Battery autonomy : Android 5

One of the Achilles heels of almost all mobile devices on the market today is undoubtedly represented by the battery life . It is difficult to get over a day of use before needing to connect the device to the power outlet to carry out charging. 

Google has considered the issue, announcing the debut of Project Volta with the next release of Android. According to information available, it is a set of tools available to developers and users, whose task will be to optimize the battery life.

Battery Historian will instead be a system of analysis that automatically detects the applications and processes that contribute most of the duration of charging, taking action to remedy it. The first tests showed that the two technologies add about 90 minutes of extra life on your smartphone Nexus 5.

Android-l-feature-better-battery-life

Personal Unlock : Android L

The integration between Android and Android Wear will be deep enough to unlock the smartphone and tablet by simply bringing one smartwatch . It is in this way that works Personal Unlock , a new method developed by Google to speed up access to the homescreen of the operating system, which effectively relieves the users from the obligation to enter the PIN or to make the traditional gesture of scrolling every time that wakes the device from standby. You will need to verify their reliability. In fact, many will remember the security issues related to the use of Face Unlock , launched by bigg with the Ice Cream Sandwich version of the platform.

Android-Personal-Local-specifications

Notifications : Android 5

The notifications  are the means by which applications interact quickly with the user, bringing to his attention updates, messages, news and any other type of information. One aspect of fundamental importance for a mobile operating system, which the group of Mountain View plans to improve with the introduction of “The release” . 

Besides being able to synchronize any notification with small display Wear of Android, the platform will allow you to consult them directly from the lockscreen, even allowing you to interact without the need to unlock the device.

This translates, for example, in the possibility to reply to a text in a few seconds, or to delete unwanted emails even before the unlock. They will then separate the most important notifications, shown immediately, from the second floor, relegated to the background. 

Again, if you are running an application in full screen as a game or playing a video, the reception of a call the app will not be hidden and will continue to work with the operating system that will simply show a pop-up in the top of the display with details on the contact’s name, likeness and buttons to answer or reject the call.

Exit : Android L

The launch of “L release”  will be officially in the autumn, probably in conjunction with the arrival on the market of the next Google branded smartphone, perhaps the Nexus 6 . Regarding updates, all devices of bigg should receive an update official by the end of the year, except for the Galaxy Nexus (which has already missed the appointment with KitKat), the first Nexus 7 and the Nexus 4, now out of the 18 months of support provided by the group of Mountain View.

Developers can immediately get their hands on the characteristics of the new Android , thanks to the preview provided by the search engine. This will almost certainly lead quickly to the release of the first custom ROM based on the release distributed through unofficial channels as the now well-known community XDA Developers.

Many platforms, a unique ecosystem : Android 5

What emerges from the analysis of new products announced at the opening keynote of Google I / O 2014, its intention to make Android a real ecosystem , breaking down the boundaries that have hitherto relegated to the platform and operating system for smartphones tablet. 

The show’s debut Android TV for entertainment in the living room, Android Wear for wearable technology and Android Car that will take the green robot in the passenger cars.

The goal is to offer users an experience that will enable them to move from one screen to another in an intuitive , seamless, unifying the interface between mobile devices, smartwatch , television, notebook computers, desktop computers and dashboard car. 

Emblematic of the slide shown by Sundar Pichai on stage at the event (attached below), which clearly shows the integration between the various platforms.

ARM Processor for Wearable Technologies

wearable-tech-arm-processor

infographics-wearable-tech

Wearable electronics market owes its rapid growth, primarily on the processor architecture ARM. Simple devices, such as fitness and smart bracelets watches Pebble use processor ARM Cortex-M3 (here and below the words “processor ARM Cortex-…” we will have a view of chipsets using these nuclei – approx. translation. ) for processing of information from the sensors, as well as auxiliary Cortex-M0, which acts as a Bluetooth-controller and consumes very little power.

In the premium segment of wearable electronics line chipsets ARM Cortex represented more broadly, including models Cortex-A5 and Cortex-A7, dealing with complex calculations, graphics cards, ARM Mali, as well as processors that handle video and display it on the screen – they are important for devices with large screens. In this energy-efficient Cortex-M0 processor is often used as a hub of information processing sensors.

Importantly, ARM as no other company feels wearable electronics market growth because it gives her and partners, including ST Microelectronics, Nordic Semiconductor, TI, Freescale, Qualcomm and other new opportunities for development. Bought or intend to buy wearable gadget? Most likely, it uses an ARM Cortex-A lines or Cortex-M. These chipsets use real-time operating systems (RTOS) in the case of low-power processors and more advanced operating system in the mid-and top-end processors segments.

Knowing processors Cortex-A and Cortex M, which play an important role not only in wearable electronics, but entry-level smartphones, you can better understand the purpose of their use in various devices: chipset Cortex-A7, which will be equipped with wearable gadgets and smartphones, are often quite different electronic circuits. Nevertheless, we want to start with a modest Cortex-M.

ARM Cortex-M

Embedded Processors line Cortex-M – the most energy efficient and are used virtually everywhere, often in a general-purpose microcontrollers, sensors and controllers, USB and Ethernet. These can be found in the network and office equipment, alarms, displays, power supplies, hard drives, and medical devices. And this is only a small piece of equipment that uses the processor ARM Cortex-M, volume of production in the billions per year.

Despite the fact that in the line of Cortex-M presented only four chipset, they have ample opportunities for individual configuration, which is based on the frequency of the processor and its use scenarios – ARM announces more than 3000 available configurations that offer its partners.

CortexS

     

Second from the left in the above image processor, Cortex-M0 +, is the most energy-efficient chipsets of ARM. Based on the architecture ARMv6-M, Cortex-M0 + uses a two-stage ordered system of power, and compares favourably with the Cortex-M0 presence of block memory protection (he also has a Cortex-M3 and Cortex-M4) and single-ended input bus-input helps further reduce power consumption. Furthermore, the chipset has tiny size, and is tailored to its holdings of 12,000 logic gates.

Cortex-M0, meanwhile, uses a slightly more complex three-stage power supply system, which increases the computational capabilities of the chipset, but at the same time, increases power consumption. More simple design makes Cortex-M0 affordable chipset in the family ARM Cortex, which can be used for general computing and control input-output. There is also not shown in the diagram Cortex-M1, but it was designed specifically for FPGA (FPGA) chips.

Chipset Cortex-M3 and Cortex-M4 more have more powerful central (CPU) and signal (DSP) processors, effectively cope with the calculations of floating point numbers. Both chips are based on the architecture of ARM v7-M and can operate at speeds up to 200 MHz – it all depends on how fast they want to make the manufacturer.

PowerS


Still, as far as these small and energy-efficient chipsets? ARM reveals rare maps, performance issues in this series, primarily because manufacturers can flexibly configure the chipset used by the kernel. Despite this, make a rough impression of the family ARM Cortex-M can be on the table above.

Made on 40-nanometer process technology Cortex-M0 consumes 4 microwatts per megahertz, and the transition to the Cortex-M0 + this value is reduced to 3 mW. Frankly, it is very small: it is enough to recall that microwatts – is a millionth of a watt. This way, when operating at 100 MHz (which is a lot) Cortex-M0 + consumes one ten-watt, with an area of ​​the CPU 0.009 mm ². The smallest area of ​​the chipset available from Freescale Kinetis KL03 and is 1.6 x 2 mm at a frequency of 46 MHz – at such a scale chip can fit in a recess ball golf.

Optimization of ARM Cortex-A for wearable electronics

It has already been said that the Cortex-A processors for smartphones and wearable electronics – two very different things. ARM provides its partners how to use the various IP (CPU registers) for each device, and it is not simply a change in the clock frequency or voltage drop, as one might think. In the end, wearable devices for stand-alone operation is much more important indicator than performance, so you have to use other technologies.

wearable-solutions

Shown in the image above combination of Cortex cores and Mali graphics accelerators are used in three types of devices: smartphones middle segment, budget smartphones and smart watches. The key point to note: processors Cortex-A7 can be used in all three types of gadgets that achieved by reducing their energy in different ways. But how exactly is this done?

 Cache-size

The modular structure of nuclei chipset Cortex-A series allows manufacturers to design them according to high customization capabilities, especially in regard to energy consumption. When simplified, then, for example, processor cache is beneficial for productivity, but has a negative effect on consumption. Most chipsets for smartphones using core Cortex-A7, have a 32KB cache L1 (first level). Reducing its volume up to 16 KB can not only reduce the required chip energy, but also to make it more compact dimensions. In addition, these actions do not greatly affect the performance, especially for portable devices.

While the reduction in L1 cache able to lower power consumption chipset, it increases the load on the L2 cache (the second level).Nevertheless, continues to work with partners to reduce the size L1 cache is because the performance of portable devices hardly drops even when using a minimum of the second-level cache. Therefore, the development of chipsets for mobile devices, it is necessary to rely on reducing the cache to achieve low power consumption.

What else can make partners ARM? For example, they may refuse the use of an optional instrument NEON SIMD, harder to reduce the overall size of the chip. Despite this, such a decision is likely false economy, because it at least allows to reduce the area of ​​the chipset, but adversely affect its performance due to integration of this tool with nuclei.

Leakage

In addition, partners can consciously choose optimized, energy efficient manufacturing process. The implications of this are deep enough: as truncated potential frequency processor core does not turn out to disperse up to several hundred megahertz and maintain super low power drain (so called energy wasted during idle CPU) which can be reduced to 95%.

As has become clear in creating wearable devices must take into account the cache architecture and workflow. As a result, can achieve high efficiency and small size of the chip which would not be possible by simply changing the operating frequency and processor voltage.

Modular technology ARM allows its partners to create processors that are suited for specific tasks, so the chipset on the Cortex-A7 in the smartphone may be different from the same chipset in a handheld device. Moreover, there are no universal solutions.Innovative companies that conduct research, can create fundamentally better products, in comparison with ready “box” solutions.

As we will soon see that the architecture behind wearable devices evolves with them. Alas, there is no magic technology that can increase the battery life of smart hours to several weeks or months, but careful work on chipsets and new technologies allow manufacturers to endow their devices the ability to work longer between recharges all, while maintaining their performance.
