Four Aspects of Android App Performance Optimization

Speaking of the Android system phone, most people's impression is that it has become a bit stuck after a while, some programs crashed inexplicably during the running, open the system folder and find a lot of files, then use the phone The butler App constantly cleans up and optimizes, only to feel that the running speed is slightly improved. 

Android App Performance Optimization

Even if the mobile phone scores far ahead in the performance of various performance software, it still feels that no matter how much memory space is not enough. I believe that every user who uses the Android system has had similar experiences. Indeed, the Android system is not as fluent as the iOS system. 

Why, when viewing the hardware configuration of the mobile phone, the Android device will not lose to the iOS device, or even More powerful than it, the key lies in the software. There are many reasons for this phenomenon. Simply list the following points:

In fact, in recent years, as the Android version continues to iterate, the Android system provided by Google has become more and more fluent. The latest release is Android Oreo (8.0). However, the Android mobile phone used by most users in China is a customized version of major manufacturers, often not the latest native system kernel, and most of them may still stay on Android 5.0 system, even the proportion of Android 6.0 or above is still small. , the update is delayed.

Since the source code of the Android system is open, everyone can modify the source code as long as they comply with the corresponding protocol. Then the domestic manufacturers will transform the Android-based source code into their own released system, such as the familiar MIMI system of Xiaomi mobile phone, Huawei. Mobile phone EMUI system, Oppo mobile phone ColorOS system, etc. Since each manufacturer has modified the Android native system source code, this will cause a problem, that is, the famous Android fragmentation problem, the essence is that the application compatibility of different Android systems is different, and the consistency is not achieved.

Due to various Android fragmentation and compatibility issues, Android developers need to adapt to different systems when developing applications. At the same time, the development level of each Android developer is uneven, and the written application performance also exists. Different types of problems lead to different user experience during the use process, so some users will be converted into Android system problems, which will affect the evaluation of Android phones.

Performance optimization

The key point I want to talk about today is Android APP performance optimization, which is what you should pay attention to when developing an application, how to better improve the user experience. A good application, in addition to attractive functions and interactions, should also have high requirements in terms of performance. Instant applications are very distinctive and may attract some users in the early stage of the product, but if the user experience is not good, Will bring bad reputation to the product. So how a good application should be defined? There are three main aspects:

Business functions
Logical interaction
Excellent performance

As we all know, Android system as a mobile device-based operating system, hardware configuration is limited, although the configuration is now more advanced, but still can not be compared with the PC, the use of CPU and memory is unreasonable or resource-consuming For a long time, you will encounter stability problems caused by insufficient memory, and problems caused by too much CPU consumption.

When faced with problems, everyone thinks about contacting users and then checking the logs. However, the feedback on performance problems is not very difficult to find. The logs are mostly useless. Why? Because most of the performance problems are not necessarily problems, the problem location is difficult to reproduce, and there is no key log, of course, cannot find the reason. These issues greatly affect the user experience and feature usage, so it's important to understand some of the performance optimization solutions and optimize our application in real-world projects to improve the user experience.

Four aspects

The performance issues of the user experience can be summarized into four categories:

Power saving, provincial traffic
Installation package small

What are the causes of performance problems is the same reasons, there are different, but in the final analysis , nothing more than memory usage, code efficiency, appropriate policy logic, code quality, installation package volume of this kind of problem, finishing categorized as follows :

As you can see from the figure, creating a high-quality application should aim at four directions: fast, stable, provincial, and small.

Fast: Avoid the occurrence of stagnation when using, fast response, reduce the waiting time of users, and meet user expectations.

Stable: Reduce the crash rate and ANR rate, don't crash and become unresponsive during user use.

Province: saves traffic and power consumption, reduces user cost, and avoids the phone to be hot when used.

Small: The installation package can reduce the installation cost of the user.

To achieve these four goals, the specific implementation is the problem in the right border: stuck, memory is not reasonable, poor code quality, code logic, installation package is too large, these problems are also encountered in the development process The problem, in the realization of business needs, also need to take this into account, take the time to think, how to avoid the function after the completion of the optimization, otherwise the maintenance costs will be increased after the implementation of the function.
