Unconsciously, Android has entered the ninth year, next year will usher in ten years old. In the ever-changing industry, Android is already a letter of the veterans. In the last ten years, Android evolved from a functional point of view, compared to competitors more impeccable, and the design also used the acclaimed Material Design. It can be said that android is already one of the most complete mobile phone system.
Android in the past decade of evolution, adding a lot of new features, but at the same time some of the classic design has also been eliminated, into the Android players lingering memories. So what are the classic designs that have now vanished? This together to inventory it!
If you are an old Android player, you should be impressed by Android menu keys. In the early years, Android system keys are the most classic of the three King Kong, namely the return button, Home key and menu key, the vast majority of App need to use the menu key to call out more features. However, the three King Kong key is now changed, the menu key is replaced by multi-tasking key.
Android this change mainly occurs in the Android 4.0 era. In Android 4.0, Google introduced the Holo Design interface design language for Android, App's menu function was moved to the Action Bar, which is the top of the App top column. To the Material Design era, this layout was inherited over. Since there is a menu button on the screen, you do not need a system menu key. And Android more and more attention to multi-task experience, the menu key is eventually replaced by multi-tasking key.
This is from Android 4.0 began a comprehensive introduction of Android interface design (Android 3.0 only introduced flat panel system), brought an unprecedented changes in Android UI - such as the above mentioned menu key disappears, appeared in the Holo design when the bit The In the Holo design before the emergence of Android interface can be described as rough, no design at all, by many people as a rough imitation of iOS. Holo interface introduction, so that Andrew finally has a unique design style.
Holo interface, although not gorgeous, but it is very taste, even more than iOS was designed to be more modern wind design. Holo design emphasizes large content blocks (such as cards) and simple, orderly layout, and now many of the classic elements of Android still inherited Holo, such as the Hamburg menu, the interface sliding in the end of the animation and so on. Most importantly, Holo design brings standardization, which makes a lot of Android App is no longer a simple application of iOS applications, but in accordance with Android design specifications to develop, Andrew finally have their own visual style.
U disk mode
Many friends will see here there will be doubt, Android can not always be used when the U disk, why U disk mode is the disappearance of the classic design of Android? In fact, Android can now be used as U disk, and before the U disk mode is not the same thing. You have careful observation, it should be known to Android now want to choose U disk "MTP mode", rather than the previous "USB mass storage device" mode - this is the real U disk mode.
What is the difference between the two? In short, the previous Android U disk mode will Android machine storage space directly mounted on the PC system, so that the storage space of Android identity PC system in a disk partition, and U disk is no difference between the operation The And now the MTP mode, and will not put Android storage space for the PC disk partition, but only through the MTP protocol to transfer data. The two designs of the user experience, there is a huge difference.
First talk about the advantages of U disk mode. As a direct storage space for the PC drive letter, so you can browse on the PC to modify the Android file, transfer speed is also very fast, download the software can directly download the things to Android machine, do not need to download to Local re-copy. But U disk mode problems also affect the user experience, when you put Android when the U disk, Android system can not read the machine files, and once Android use the PC does not recognize the disk format , Such as ext4, etc., PC can not read Android storage space.
Previously Android owned "USB mass storage device"
Once the U disk mode is turned on, the phone will not be able to read the stored data
In contrast, MTP mode compatibility is better, as long as the PC supports MTP protocol, regardless of what kind of disk format Android, you can read the data. Although MTP is slow, but PC and Andrew can operate the machine at the same time, but also more secure, PC can not modify some of Andrew's key data. For example, PC infected with the virus, the virus will be difficult to pass through MTP to destroy the Android file. Of course, MTP inconvenience is not directly modify the file, you need to copy the file out in the first operation.
For users, MTP is clearly less prone to problems. Therefore, the performance of more powerful U disk mode is also eliminated in the reason.
App moves to the SD card
In the early Android, generally can use SD card for expansion. Although App is not installed by default to the SD card, but through the system itself, or App2SD like a small tool to move the App to the SD card. An early pile of Android machine comes with capacity only 4G, so for some of the larger App, such as the game, the App moved to the SD card is still significant. At the same time, SD card can also be pulled out at any time when the U disk, with more convenient.

The previous Android system can move the App to the SD card
However, after Android 6.0, Google abandoned the feature. Although there are still Android support SD card expansion, but by default you can only music, video, photos and other data stored in the SD card, App can only be installed in the machine space, can not move to the SD card. If you must put the App into the SD card, you must integrate the SD card and mobile phone internal space, the system automatically format the SD card and encryption - but this time to lose flexibility SD card, encrypted SD card can no longer Just pull out when the U disk, or plug in the other machine immediately used. Google's settings may be based on stability and security considerations, Android 6.0 after the system used SELinux encryption, greatly reducing the probability of equipment security problems.
Google abandoned App to move to the SD card, switch to SD card to the internal storage of this setting, pay more attention to security, but brought inconvenience. Now, even the capacity of 16G have been close to the elimination, a lot of Android machine is starting 32G. Therefore, fewer and fewer people need to install the App to the SD card, the design was so changed, it is reasonable it is reasonable.
Android system is still high-speed development, the future will have more and more features to join the system which, and perhaps also have a well-known design to die. What are your expectations for Andrew's future development? Welcome to comment on the comments area.
