Android Performance Comparison of advantages and disadvantages in actual development

The reason why Android mobile phone operating systems have received so wide attention is that their performance is essential. Here, we will analyze the Android performance from its advantages and disadvantages and the application advantages in development, so that you can further master this operating system.

Android performance advantages:

1. Small memory usage

Android is a multi-task operating system. All recently running programs are resident in the background. In memory management, the system automatically kills recent inactive processes that occupy the memory, you do not need to manually close the program like Symbian and Windows Mobile.

2. Running Speed

The running speed is also one of the strengths of Google mobile phones. Although its core processor frequency and memory configuration are not the top-level, the Android platform has a high speed performance, many people who have tried this machine have always liked its smoothness. With the guaranteed speed, it is easy for other rich applications.

In addition, it is reported that the Android platform does not have high requirements on the hardware configuration of mobile phones, so there will be no embarrassing situation with a high threshold for the Linux platform.

3. Beautiful Interface

The first is no less than Apple's iPhone's gorgeous UI interface. The touch mode with a higher degree of freedom explains the superb handling performance of the mobile phone, and the full-keyboard attachment of QWERTY undoubtedly caters to the usage habits of more users.

For the Android 2.0 operating system, from the current summary and summary, compared with the previous version, the main improvements have been made, in addition to having a brand new user interface, the new version also includes integration of native Microsoft Exchange mail service support and Facebook features, browser improvement, and fully updated map applications. Specifically, the features of the new system are mainly reflected in the following:

1. The overall operating speed of the operating system has been improved

The overall operating system speed is faster, especially the browser performance is greatly improved. In addition, the browser now supports double-click screen scaling.

2. Integrate Facebook friends into the contact function without installing third-party software.

3 The entire system supports voice control in many places and has an independent control panel.

4. Google map service update

5 native support for Microsoft Exchange mail service, and further improve the system's mail functions, such as integrating multiple different accounts to provide a unified mail inbox, which is more convenient and convenient to use. For those who share their happiness with others,

6. the browser has a new operation interface, and the URL address input box is re-created, and the Favicon is displayed. However, the current version does not have Flash 10, but the performance is slightly better than the HTC custom browser, a little close to the iPhone 3GS page browsing speed. Unfortunately, this version of browser still does not support multi-finger touch. You can only double-click the browser to achieve scaling. In addition, the new "Car Home" Application for drivers provides easy-to-use and quick links for various features, and allows users to conveniently use voice control functions, it is easy for users to drive. For example, you can search by voice, view maps, select contacts, and search for your mobile phone. When you say "map to gas station" when you drive, your mobile phone will be able to display the current route map to the nearest gas station via Google Maps.

Convenience of Android performance in development:

1: The system comes with a large number of encapsulated controls, and can customize the control, easy to use, improve programming efficiency

2: The system comes with a variety of debugging tools, which can well meet debugging and monitor program running conditions, such as memory usage.

Interface layout thread usage.

3: The system provides a large number of function libraries, allowing programmers to focus more on business logic.

Disadvantages of Android performance:

1: Security and Privacy

Due to the close connection between mobile phones and the Internet, it is difficult to keep personal privacy confidential. In addition to the personal footprints that are intentionally or inadvertently left on the Internet, the Google giant is always standing behind you and wearing everything. Therefore, the depth of the Internet will bring about a new round of privacy crisis.

2: Unsupported hardware

Android performance deficiencies in development:

1: The simulator starts slowly.

2: The visual editing interface is unfriendly.

3: the randomness of the UI design makes it difficult to develop beautiful interfaces.
