Where is the combination of Android Device IOS?

/Ticwear team

IPhone Android Wear connection? This sounds a bit far-fetched, but foreign media said Google is working to make based on the Android platform for Wear smart watches and iPhone compatible. According to information obtained, Android Wear smart watches will be done by supporting applications on the iPhone to interact. But will have only a few basic functions, such as notification, call alert, Google Now environmental features such as information cards.

While Apple released Apple Watch, but Android Wear many styles and low prices make many watch users, and Apple watch Android watch between two camps, Google competing with Apple Watch perhaps the most simple success is to make compatible Android Wear device iOS. It sounds attractive, but others said, it's almost impossible, then Apple has the potential to completely open and let Android do Wear connect iPhone? Perhaps, from their past and present say.

Confrontation between two systems

Since the iOS born in 07, Android next year followed by, Android and iOS, as two major systems, confrontations continued over the years, have each produced a bunch of fans which is more important, win or lose, has not yet reached a conclusion.

IOS from Apple's OSX, is UNIX systems, OSX has a history of almost 10 years, is the evolution of the underlying software architecture from the kernel. IOS using ObjectivC this ancient language to do development.

Based on Linux and Android is Google, Android is not strictly speaking a Linux system, it has no Linux XWin, no glibc, the lack of a set of standard Linux programs. Most Android applications are developed using JAVA, run on Dalvik virtual machine (5.0, then switched to Art). Google also changed a lot of things on the ground floor. Android is a whole new operating system.

IOS being pre-loaded with many Google services, such as search, maps, YouTube, iOS YouTube,Google removed in version 6 Beta map service into its own service, although after the release of Apple map we have received much criticism and questioning, but in 2012 since the Apple map has a number of improvements, its accuracy is also evolving.

Android, iOS than on the part of the experience, as users often complain about electricity, instability and insecurity problems, as an open system, Android system developers to play bigger and have more degrees of freedom, do some functions at the application level to achieve the iOS system, and consumers have more models to choose from. Victorias Secret case for iPhone 6

But at the cost of ecological environment is not well controlled, causing a lot of malicious, sophisticated enough applications appear, affects the Android system's user experience. Android user interface experience was on par to iOS, and also has its own great places, such as mobile phone notification Center, led notification light, no physical buttons and so on.

IOS is a better user experience. Advantages include uniform and smooth user experience, rich high quality App, good ecological system, the relative safety of the system. Sealed system attendant is a developer on the iOS device can do relatively little, so far, such as not and Android device via a Bluetooth connection.

Multi-touch (Multi-touch) first patent of iOS, Android follows have a touch screen (Multi-touch) function, follow the situation until recently, Android took the lead in the flat, followed by Apple, flat iOS7 system UI, Android after the city pulled one back, and introduced a new design and interaction style (material design).

IOS and Android device integration technology

From a technical side, connect iPhone Android Wear watches in two ways:

Low-power Bluetooth (BLE), this connection does not need to be certified by Apple, only wants to receive Bluetooth Watch installing a notification application. Android support BLE time relatively late (until 2013 to launch Android Bluetooth 4.0 BLE properties of 4.3), and because all manufacturers of Bluetooth driver quality Android Bluetooth stack is itself unstable, making Android BLE on the development of the difficulties. Android official Bluetooth in the 4.3 release. 4.3 and 4.4 after opening BLE of the Center (Central) for this interface. Starting from 5.0, although Android can be used as a peripheral (peripheral), but all support this feature is Google's own son Nexus 6 and Nexus 9.

https://www.youtube.com/watch?v=up5lfdzjJIw For other Android developers, not as a peripheral development will bring many difficulties, such as watches and mobile phone pairing connect and reconnect will be more complex. Bluetooth driver problem is the most difficult problem in the development of quality, such as strange error code somehow disconnected, and so on. Android's own Bluetooth stack bug is endless, AOSP searches for Bluetooth Issue Tracker will have more than more than 400 unsolved bug.

Classic Bluetooth, this way you can support faster data transmission, but this way the connection requirements the device must pass Apple's MFi (Made for iOS) certification. Through this certification, Apple sees this device must be made meet Apple performance standards. More trouble the entire certification process, including the development of certification and manufacturing two parts, technical details need to be submitted to the Apple products and manufacturing processes, including product packaging design. Allegedly, MFi certification pass rates are very low. So far, there is no any Android Wear equipment certified by MFi, I do not know whether equipment vendors do not have to apply for certification, or Apple rejected all applications.

IOS and Android wear connection

Connected to what makes it difficult for iOS and Android system?

1) iOS platforms

IOS is not open and restrictions placed on back-office applications for Android and iOS are connected more difficult. The Android core source code is open, developers can go and see for yourself the source of the problem to solve the problem. IOS is not open source, a few rare problems it is difficult to locate exactly where the problem was Android or Apple, and if Apple is no solution to the problem should just wait for Apple to update. IOS background applications restrictions is another difficulty.

2) low power Bluetooth (BLE) itself

BLE new programming, and low power consumption make it harder for the development. Like traditional Bluetooth development and TCP on network programming, developers only need to manipulate the socket to send and receive data. BLE without socket, the concept of service instead, characteristic, and descriptor:service is a service, a BLE peripherals can broadcast multiple services, each service has more than one characteristic, a channel for transmitted data. Each characteristic that can send a maximum 20 bytes, can be configured with descriptor is read or write. BLE interface is very primitive, developers need to do it again after the package to transfer data more efficient. Another BLE limits is low power consumption. According to Wikipedia, of classic Bluetooth low power Bluetooth data transmission rate is one-third. In practical application, go ask find BLE data rates still lower, only about 1% of classic Bluetooth. Go ask Ticwear test device, BLE transmission speeds of around 0.5KB - 2KB per second, which means that if you transfer a song with BLE 4MB MP3 will need at least half an hour.

Now way of connecting you to the iOS and Android Watch system

In January this year, go out and ask the team have been published in a Chinese watch operating system Ticwear connection iOS features. In February, foreign developers Mohammad also announced the implementation of the function. Recently, Google Android Wear team also disclosed that it would support the iOS, estimated by BLE manner.

Due to the BLE greater restrictions on the connection, the actual data transfer rate is only around 1KB per second, such a low data rate determines the BLE communication can only support a small amount of data, such as call alerts, notifications, and so on. Larger amounts of data transmission tasks like voice search, download and OTA upgrade is difficult to achieve.

IOS Ticwear connections and different from other similar applications on the market, in addition to supporting messages pushed outside, Ticwear iOS Assistant support to replace the dials, time synchronization, phone calls and other features that only AndroidWear and Android mobile phone is connected. In order to implement these functions, go ask the BLE was repackaged, Android allows applications to seamlessly connect iOS devices. Support for these features requires users of iOS Ticwear iOS Assistant devices are switched to Bluetooth can also be used in the background (because using a low power Bluetooth, users no need to worry about power consumption). But iOS on different versions of the Bluetooth application in the background stay definition is different, so the user does not disconnect Bluetooth connection will appear on a regular basis so as to affect the user experience.

Android and iOS connection is currently mainly relies on WiFi, Bluetooth need pass Apple's MFi certification, few Android devices through this certification. Android watches currently connected iOS device can be Ticwear or some other solution. Apple watch connections programme there is no Android phones.

Go out and ask the team believes that Apple sells watches a big objective is the promotion of iOS phone sales, so in the short term can support Apple apples should be no incentive to Watch connect Android phone or Android Wear at all iOS devices. Under pressure from all sides, Apple finally is going to make some quality Android Wear equipment certified by MFi, iOS and so as to allow these devices to achieve the perfect fit. However, because Apple just released Apple Watch products, because of competition concerns in the short term should not let Android Wear the equipment certified. But developers will do the two camps devices can interconnect. Because then both Android Wear Apple Watch supports WiFi, Bluetooth limit does not exist, their possibilities of Internet is full of imagination. Victorias Secret case for iPhone 6

Electric buses will soon be completely replaced the ordinary buses

　　In recent years, the adjustment of energy structure, has always been a lot of scientific and technological research directions. In contrast, in the highest places on the use of energy in modern society, is probably in the transport area. Therefore, adjust the energy structure by changing the power becomes more important. Plug-in cars and sometimes face various problems, such as in the charging inconvenient problems remote areas will have, this time will be gasoline more useful. However, if it is used in the city, the problem apparently does not exist. For us, therefore, the bus may be the first comprehensive "time" type of car.

https://www.youtube.com/watch?v=0oNA_SHgPb8 　　Over the years, Proterra companies received support from Tesla. Recently, the company announced that it would launch a new electric bus, which in the case of full charge range of 420 km away. In China almost all bus routes in the 40 km is calculated, it can be used in the case of full power about 5 running back and forth without recharging. Apparently the requirement can be met.

　　At present, the electric bus is equipped with a total of 8 batteries, a total volume of 257kWh, the body is made of advanced carbon fiber and composite materials. Proterra senior considered that the vehicles can be equipped with 10 batteries, if so, the electric bus can run about 480 km away. This figure will present the maximum mileage of BYD's electric bus full of about 255 kilometers far behind. Historically, Proterra and BYD's electric bus is the main competitor.

　　However, competition is the driving force. Perhaps such a virtuous competition will promote the development of electric bus industry, so that we can more quickly into more reasonable "Electric transportation age". Cath Kidston note 4 cases

OZAKI 3D tempered one surface film review

IPhone6S brings the iPhone accessory market hot hot, especially film market is very active, users in the choice of a suitable foil to protect in addition to considering the possibility of a good effect at the same time, also put forward higher requirements, such as will not affect devices in appearance? Feel really bad? Will not affect the use of touch-screen functions? Under these circumstances, can't make out a stick, does not affect the feel, protects your screen also does not affect the film seems to be the best choice for everyday use. This uses a very interesting film, OZAKI 3D one surface of steel film, started teaching you intended to create a "no sense endearingly" of new equipment.

This 3D surfaces from OZAKI steel membrane is a product fit 6S, keep the thickness 0.3mm, pressure-sensing will not be affected, so that 6S use of 3D Touch user can rest assured. Effect of 9H hardness in terms of scratch-not to mention, more than enough to cope with common objects used in your handbag. As to why this steel membrane is very interesting, and perhaps because of the legend of "6S camouflage course" which will verify, OZAKI's seamless technology and 3D surface fitting, whether as legendary as "perfect"

First teach everyone to distinguish between colors. Right corner of the back of the packaging, very small write BK or WH, have a variety of equipment bought post film users tell more about it and your device is appropriate. (I didn't find that three white people in this key marked)

Like an Easter Egg hidden in the trailer of ... ...

From the package, OZAKI design can overcome a lot of users. Fine and founder of packaging box on can let people front a bright, open box, you also can from it of arranged way Shang feel to "tall Shang", parts of plastic packaging bags bonded in box Shang, guarantee has in box in the not appeared collision gangster rub, interesting of is although packaging bags all fixed, but actually packaging bags are not sealing, is using bent folding of way fixed accessories in which. No violence can also remove all accessories.

Virgo can be relieved, remove and still be able to get the complete package.

Standard accessories list

Hardness and flexibility in a small test is probably can bend to such a degree, free of debris flying, the protective effect is very good. Victorias Secret case for iPhone 6

https://www.youtube.com/watch?v=up5lfdzjJIw Not to mention in anti-scratch, General steel membrane that can be reached is no problem here, of course, taking into account the general public has not put a mobile phone and ring, so don't worry about it.

Understanding can begin after the standard foil, foil process by hand to shake very much layman to complete. In fact attached to the 3D surface of steel film for manual's requirements are very high, because we would have to do is "do not see posted film", so careful it is essential.

Screen cleaning

Film can be performed after the cleaning is completed, after the alignment holes ... ... A shaking of his hand accidentally labeled. This case needs to mentioned that its automatic adsorption technology, and it is also closely related to the precise holes, after contact with the screen is perfect and fast bonding, little bubbles that appear in the upper-right side of two simple scraper scrape disappeared.

Instant film, bubbles simply scraping

After a closer look found that basically don't see posted the film. It has very accurate holes, corners are very fit, because the film itself is only 0.3mm from the side view, the seams are not particularly significant.

Compare and 2.5D film, basically not posted in film

Tried black foil

Comparison of 3D surface fitting results perfect

Transparent quality indistinguishable from before the film

If OZAKI on the same brand of protective shells, looks exactly like is bare metal. Looks like a new phone, I believe no one can see your device is "armed".

With a variety of shell effects are good

0.3mm has little effect on the thickness used in hand, combined with a relatively thin shell thickness also have not increased much, overall, feel good. Victorias Secret iPhone 6 Cases

3D TOUCH functionality is not affected

Overall, this film did "not endearingly". 3D surface in appearance to achieve a "perfect hide films" this; see has full functionality on the thickness does not affect the use, feels much different protection not to mention, is also the significance of the film itself. Overall, choose this OZAKI 3D one curved surface tempered glass film can really make your phone in the "armed" cases, giving a "this is bare-metal" feel. Users who have high requirements for appearance and use, this film should be able to reach your expectations.

Scientific mad men 16 years snake "test biting" over more than 160

　　Weifeng Web on January 23, saying that good: once bitten, twice shy of the Decade. Of course, for people living in modern society, the probability of contact with snake creature itself is not high, the bite is more likely to be minimal. However that had access to an American in 16 years to be bitten more than 160 times, on average 10 times a year and this life back to what extent can we do. Marcelo Burlon iPhone

　　Of course, he is not because of bad luck or what. Because the person named Tim fried is a science geek, and he has done so in order to test the body's ability to resist HIV. Under the United Kingdom, the daily mail reported, fried has personally shown for Taipan snake and black Mamba bite in its two arms. Cut immediately to swell up a big bag, and, as the most toxic in the world two of fierce snake, common even in one of the two snakes gently bite could kill in a few minutes. Fried Live!

　　He said: after a bite of pain made it difficult to put up with, but he is not going to stop doing it, unless one vaccine, or him being bitten to death. Believed the undaunted spirit of adventure is most people are unlikely to have, of course, deserve our admiration.

https://www.youtube.com/watch?v=8xQwrwqbp48 　　However, due to the multiple bite poisoning, he has also had a very high degree of venom antibodies in the body, according to the results of medical tests showed that antibodies for in him more than twice. Just like this, he is able to survive in such a violent attack. Marcelo Burlon iPhone

360 Eye Dyson vacuum cleaners in Japan for sale

　　Dyson (Dyson) United Kingdom-known high-tech companies, their designs tend to be more advanced. Meanwhile, the price is definitely not cheap Dyson products. Has been for a long time before the 360 Eye Dyson vacuum cleaners sold officially, but starting location selected in Japan, sold a staggering US $ 1200. Ted Baker iPhone 6 covers Ted Baker iPhone 6 covers

　　Generally speaking, in what is now on the Chinese market, spending around 2500 Yuan RMB already can buy very high-end vacuum cleaner. And if they take into account factors such as tariffs, if you want to buy a Dyson 360 Eye in China are expected to spend tens of thousands of Yuan, the price is obviously not everyone can accept. However, Dyson said, will in the next few months will be 360 Eye extended to a global scale.

　　Dyson could afford to sell it to the price, the main reason, of course, is its own intelligent features. In addition to the robot the necessary features to run automatically, Dyson also designed a unique smooth 360 Eye bottom and clean bodies and fuselage tangent, brush out. Aim of this was to avoid robots at work to the greatest degree when he accidentally inhaling working wires, resulting in some of the security risks. In addition, prior to it compared to Dyson on the hardware and software products have been improved. Can analyze the surrounding environment in order to determine the most effective and fast way to clean ground. Not only that, but its motor can spin 78,000 times per minute, is the highest suction vacuum cleaners currently on the market.

　　Said look may be worthless words: for small series, rather than spend so much money on a vacuum cleaner, might as well do it yourself cleaning, iPhone 7 save money in the future to buy it.

Social networking products in the future

One origin of the communications industry investment manager said on Twitter: "the last three days with all kinds of people (entrepreneurship, investment) talk about is social, networking, and socializing. Reduction of different terminals, expansion and influence human society a mode of communication, which deeply affects the traditional business. Real authentic, dream more dreams, more Earth dust unto dust, is the real future of social networking products. ”

So what exactly is social networking products in the future? No one knows.

But social networking products in the past just needs and now just need no major changes in the foreseeable future, it still will not have any change. Michael Kors iPhone 5S case

In a formal statement, which is called "stranger Personals". All are considered successful strangers dating product forms during a period, without exception, are known by the thing between men and women. From more than 10 years ago, chat room, forums, instant messaging, social networks, to a random post short messages (the bottle), LBS, to "shake shake shake" ... ... Social demand of the Chinese market has never changed. If you want to back, who would say that "pen pals" is not the ancestor of the stranger personals? Michael Kors replica

In fact, in the present, although there is plenty of social networking applications, of which at least half the function of making friends with strangers, but there have been new developers and applications one after the jump on the field. In addition, the applications in other areas, such as e-commerce, image, and so on, are also trying to add stranger personals features for yourself.

Why is that?

Chapter one: order social products the next chapter: the development of "stranger friends" five reasons the third chapter: "stranger Personals" behaviour guide the fourth chapter: how to design a "stranger's friends"? Fifth chapter: the platform is dead and does not affect the social significance of the sixth chapter: the outer chapters: special "dating a stranger"

Data on the mobile phone (iii): on the phone reading

"Editor's note" this paper by percentile information Senior Director of wireless services Li Xiaodong, Talking Data COO Xu Yi, Chengdu uestc Gong Liang jointly prepared.

Mobile Internet coverage of everyday life, users anywhere in the data, the data move in now and get on the Internet is not a problem difficult to break. Need we face is to get what we need from the massive data analysis of real information.

Organization and application of mobile phone data

Mobile phone data on the mobile Internet business early no doubt has great significance, but not all phones have data will be so meaningful. Social media-Twitter, for example, can also produce large amounts of data every day, but most of it is pointless.

Organization and application of mobile phone data

Mobile data needs to be reorganized in order to reveal significant information.

In today's era, the data itself is not a problem, you could get huge amounts of data from various sources; we are to produce very large amounts of data each day, the key question was how to process and analyze these data. Without processing and analysis of data, like Mary examples, just a bunch of straw, worthless.

Find a needle haystack

Data processing, analysis from a large stack of straw singled out a PIN.

This word has two meanings:

Regardless of we from what channel, through what way get of data, large of data is no meaning of, this which only few of data is effective to, can from obtained some has law, and has value of information of, original data need cleaning, and finishing; (this is for mobile Internet more obviously, generally, almost 80%-90% of mobile application data are is no value of, only not to 10%-20% About contains information required for subsequent analysis of data), we need to work through the subsequent data mining, disorganized pile of straw to find lost in the layers of representation of a needle rather than a straw! Apparently, not simply through the statistics would be available; is more complex than the statistical analysis of algorithms, from simple associations of overly complex logic levels.

In the previous chapter, we know that mobile phone data on the diversity of sources and different mobile Internet portal, the emergence of different applications will lead to different data, and these different data and supporting different business, and there may be some crossover between different business applications. In view of these characteristics, here based on these features a simple introduction to big data organization, mobile phone data of organization structure in the following diagram can be used.

Mobile data is organized

The structure can be seen from above, mobile phone data organization consists of three main parts: raw data storage, computing and business data store layer

Original data store layer Paul Frank iPad Air Case

Main stores of different entrance data, different coexistence of different data fields are separated at this point of entry data sets are independent of each other, without any contact between the data sets. The benefit of this is that we can ensure maximum data integrity, and correctness.

The compute layer

Main task of this layer is to the original data store access data mining processing and mining results classification according to different business. Mining processing can be divided into the following two points: ① internal analysis of different data fields, mining. Researching on the Mining Association analysis between different data fields. Classification is mainly mined results classification, such as music, food and beverage, advertising and other applications.

Business data storage layer

Business data storage layer is to calculate the output is stored separately from the data, and data interfaces that provide applications with more explicit.

When we effectively store the data management, we can use these data for some meaningful work, especially for the mobile Internet business early no doubt has a very large significance, here in mobile reading, for example, for mobile data on how to apply to be a description.

Phone reading

Phone reading as the mobile Internet is now one of the few still have some similarities and precipitate application of, is the object of our early mobile phone application. The so-called "common" and "precipitation" is aimed at mobile applications "fragmented". Phone reading although there are a large number of fragments of time, but has been gradually formed a valuable one night early in the morning "on the bed" piece, there is relatively full time on-chip rendering behavior, a relatively complete set of user-preference information reflected in the mobile Internet.

Although many reports have shown that characterization of users on the Internet and mobile Internet has a huge difference, but I still believe, in the face of a piece of text, a picture on the preference, the feeling is not the same. Because human nature is not easy to change. Internet and mobile Internet user behavior is different, it is because the application itself uses a different, solve the problem of different causes. Is not a person on the Internet is a character, and on to the mobile Internet is another life.

This is our research on mobile reading data in the first place.

Below, we take a mobile reading project has done, for example, from finding and solving problems, results come to you in three ways.

Find problems

Through the mobile reading data mining analysis, we have identified the following problems:

(1) reading behavior similar to cities and urban

Our statistics in Hangzhou, Guangzhou and Shenzhen in a time period during which the user reading the data, get this featured top 20 in three cities in three months of data.

Statistics in the following table are Hangzhou and Guangzhou, Shenzhen, two cities in the popular books of the time coincidence counting.

February May Guangzhou Hangzhou Hangzhou Hangzhou VS Shenzhen VS VS VS VS VS Guangzhou, Hangzhou, Shenzhen, Hangzhou, Guangzhou, Hangzhou, Shenzhen 994,438 131,088,934 BC

From the table, we can guess, Hangzhou and Shenzhen, Guangzhou between these two cities reading similarity does exist to some extent.

Formula: Sim (a, b) = Same (a, b) *2/[Count (a) +Count (b)]

Sim (a, b) represents cities A,B reading of similarity. Same (a, b) is the city of A,B in a time period that common reading book in the book, Count (a) is a city in a time period that read books within books.

We can see from the table, Hangzhou, Guangzhou and Shenzhen reading similarity is very high. That is deep or hang-Hangzhou City reading is quite similar, we will consider them as reference to read ' bellwether city.

So, if you consider to do analysis of vane, more inclined to read indicator for the selected Guangzhou as Hangzhou, Hangzhou as a bellwether of Shenzhen, Hangzhou and Guangzhou can reference each other.

(2) to read "long tail" phenomenon

Found in our statistics, mobile reading market is basically on the hot list and subjective recommended to run. This makes our common "long tail" effect, and with the number of books, and this effect is even more serious!

(3) different behavior patterns of user relatively large performance difference

We the kmeans clustering algorithm (a common data mining algorithm), show characteristic differences between the various types of users is quite obvious.

Different patterns of user relatively large performance difference Paul Frank iPad Air Case

Solutions

We analyzed historical data for different problems, we feel that we can use the following method to resolve.

(1) data clustering recommended send

Through the user makes the analogy to send books, we found the following results:

Data clustering recommended send

Category: people close to 60%. These people have been reading recommended books (about e^1), the amount of PV on June 14, the day did not improve, and mentioned later significantly improved after June 20, seems to be back to the level of before the PV.

Category II: less people, only 57 people. In front of the recommended basic reading recommended books, recommended reading recommended books after large amount of PV (average e^2), and the follow-up can also be used to maintain, that the push to stimulate interest in reading recommended books.

Category III: people close to 40%. These people between June 13-17 pushes the reading books improve the amount of PV is very obvious, but beyond this time period, silent, early (June 13) reading recommended books rarely, later (June 17) read some upgrading, but also is a return to the relatively silent.

(2) personalized push

Push way because cell phones, most are recommended through the pop charts, this leads to a more popular books, which are pushed, pushed behind him. Repeated cycles, caused the long tail phenomenon, data coverage and other issues. So it is best to set according to different users different recommended methods. This can significantly improve the situation.

Result verification

As we move through the data mining process, then the user application, obtained the following results:

(1) the increase in PV

First day of the PV

From the experimental analysis, we conclude that: the total response rate for the week, the experimental group was 1.3 times in the control group.

Successfully recommended users recommending books on the first day total PV, 8.17 times times the experimental group was the control group; featured books per capita amount of PV, 15.19 times times the experimental group was the control group. Successfully recommended users total amount of stimulating PV on the first day, the experimental group was 9.62 times times the control group; all the books per capita amount of PV, 17.88 times times the experimental group was the control group. Successfully recommended users, featured book of the week in the experimental group control group of PV to about 5.45 times times recommended books per capita amount of PV, the experimental group was 4.88 times times the control group. Successfully recommended users, total for the week to stimulate PV is in the experimental group control group 7.01 times times all books per capita amount of PV, 6.28 times times the experimental group was the control group.

In summary, data mining, analysis, recommendation algorithms, mobile reading of the indicators has been significantly improved, its effect is not the scores improved, but increase exponentially! This is the charm of the big data applications!
