Android from 1.0 to 6.0 versions of the difference

Androidsystem from -years to now ( .years4months), the eight-year time version from1.0has risen to6.0, sinceAndroidsystem update speed, resulting in the marketAndroidthe device is runningAndroidThe system version is different (professional terminology is called fragmentation serious) .Year's latestAndroidversion distribution map (up to .years1months)

, you can know that the current mainstream system is three, but still some version of the system is still in use, as Android program developers, must try to take care of the various versions of the system, or your proposed solution is not perfect, for Android developers, it is necessary to know Android the features of each version, in order to develop a more complete software development program. This will enable the development of applications that can run stably on different versions of Android devices. But today's Android Learning materials are not involved in this issue. So I wrote a blog to let you know the features of each version of Android.

Six .

Android3.0 to 3.1 (3.0 honeycomb hive ):

Android 3.0 system is mainly used for Android tablet products, screen dynamic, more controllable, representative of Motorola's tablet products xoom,3.1 has also been released, but also mainly for flat products.

Seven .

Android4.0 (4.0 Ice Creamsandwich)

1. Single system

Android 4.0 will provide only one version, while supporting devices such as smartphones, tablets, TVs, and more.

2, the first-class new UI

3. Open source

Android 3.0 had previously announced that it was not taking open-source measures, but Google knew that one of the big success features of Android was open source. The pain on the tablet is bound to be avoided on the new Android 4.0, the user-centric brush machine resources will certainly make Android 4.0 icing on the cake.

Eight.

1. Android 5.0 Hello 5.0

The 5.0 version number will tell us that this is a large upgrade version.

2, based on the Linux kernel 3.0

Linux has just released the Linux 3.0 kernel for a few long time, and later it was updated to 3.0.1.

3. Buy Music from Android Market

Google has tested the nature of the launch of Google Music Beta, allowing the upload of 20,000 music to Google Cloud Server, automatically create playlists on any flash-enabled device back-up, we have reason to believe that the AppStore impact of the digital video, The availability of audio services content will also appear on Android.

4. Multi-core processor optimization

Now the manufacturers are pushing dual-core smartphones, the actual effect of how we do not comment, but Android 4.0 will be particularly for the use of dual-core and even multi-core processors of mobile phones for special optimization.

5, running speed than 3.1 increase 1.8 times times

Google's people just said, and did not mention the performance of the specific aspects of what, so we do not know whether it is about the browser, GPU or overall performance, only wait.

6. Smart parking with integrated Google TV and Chrome OS

7. An official theme engine for OEMs

With this engine, you can update to these third-party topics via Google's upgrade program.

8. A true competitor of the Apple Game Center

9. Support the existing smartphones

It is said that all mobile phones running Android 2.3 are likely to be upgraded to version 4.0, which I loved and that Google's official Nexus One and Nexus S will be the first to upgrade to 4.0.

10. New photographic techniques and virtual cameras

This will provide developers with a richer camera control API.

Nine. Android 6.0

Voice Search under lock screen

Users can directly in the lock screen state for voice search, although some Android phones now support voice wake-up function, but these voice wakes are developed by third-party vendors, and the Android 6.0 at the system level to join the lock screen voice search, which will undoubtedly have a significant improvement in the experience.

Fingerprint identification

When it comes to fingerprint identification, many users will feel that the current high-end Android phones are supported, but the fact that the fingerprint identification of these Android phones are developed by each vendor and does not support the bottom of the system. Android 6.0 adds fingerprint recognition at the system level to provide native fingerprint identification API, which not only reduces the cost of the manufacturer to develop the fingerprint identification module, but most importantly, the primary fingerprint recognition will greatly enhance the fingerprint identification payment security of the Android phone.

More complete application Rights Management

There are application notification management features in the pre-native Android system, but more in-depth application rights management can only be implemented by third-party applications. Android 6.0 further strengthens application rights management, and application rights Management is also a system-level feature, but this is not good news for those rights management software.

Doze Power Management

Android 6.0 comes with Doze Power management feature, in "Doze" mode, the phone will not detect the movement for some time, let the app hibernate to kill the background process to reduce power consumption, Google said when the screen is turned off, the average battery life increased by 30%.

Now on tap function

Now on tap is a feature that works closely with Google search, which allows Google to search from any app. For example, when talking about a restaurant, you can do Google search without jumping.

APP Links

With the app links feature, the Android platform is able to apply to Web servers and identify the link content independently. Jump directly to the app client and improve the user experience, enabling users to do more with a more sophisticated app client experience.

In addition, the Android 6.0 Google also added Android Pay to further strengthen mobile payments, but also to fight Apple pays. At the press conference, Google said Android 6.0 would start pushing next week, and NEXUS5/6/7/9 and Nexus Player would be able to get upgraded the first time.

It is necessary to explain in the previous instructions (I think and application development closely related) a total of two, the first is marked with the red font of Android 2.3, and the second is a 6.0 later version. First of all, the Android2.3 has improved greatly with previous systems, specifically, by adding NFC support and increasing SIP support (it is completely different for Android developers to develop NFC or SIP-related applications before they are added, and I'll write a blog about it later, This only shows that Android2.3 after writing NFC or SIP related programs is much easier than before, the second improvement is to change the Input method framework (mainly to the previous Java implementation into the C implementation), the result is 2.3 after the input method is more efficient.

As for the system after 6.0, the first development tool can only be used, Google's official Android Studio. It's worth mentioning that, starting with Android 4.4, the Android app has added an optional mode from the original Dalvik mode  art mode (full name is android Runtime mode). This mode causes the android run app The speed has been faster (there are also blog special introduction). android 5.0 start using linux 3.0 kernel. Here is the multi-core Processor Optimization Foundation (because linux The kernel handles load balancing for multicore processors).

Finally, to summarize, from Android 1.5 to the now the Android 6.0 It's easy to see Android the system has been developing to improve the user experience and reduce the difficulty of application development. It is not difficult to predict that the future Android system should consider the problem of video decoding.
