The reason why Android smart TV is more and more used and its solution

The smart TV industry is developing rapidly, and the current smart TV configuration is getting higher and higher, and its fluency is far superior. However, many smart TVs will slowly change cards after a few months or a year. Today, Xiaobian will introduce the causes and solutions to this problem.

The reason why Android smart TVs use more and more cards:
1. Congenitally insufficient, running a virtual machine on Linux, and then using JAVA for development, although it can reduce the development burden and obtain vast resources, but the cost of the later optimization increases more, Java does not provide any operation to release the memory (iOS The development language Object C can control the memory release), which is managed by the system's memory recycling mechanism, but memory recycling is a double-edged sword. When GC (Gabage Collection), all threads must be suspended, which is called card. pause.

2. The chaos brought about by the openness of the day after tomorrow, forced and closed, brings a high degree of unity and standard to the application of iOS, and the open Android will inevitably bring about the negative effect of chaos, fragmentation is a well-known evil, some applications are compatible More old devices, have to continue to use low-level APIs, such as WeChat, now still use API level 9, in order to be able to use on Android 2.3 system, and Android 5.1 supports API level has reached 22, the efficiency is obviously large In addition to the discount, the openness of development is a very big hidden danger.

3. Android uses more and more cards: APP is constantly reborn in the background

Today, with the development of hardware and the continuous improvement and optimization of the system, the inherent shortcomings of the Android architecture have had little impact. The performance of those flagship new machines is enough to prove that the seconds are open, smooth and smooth... never lose The same level of iPhone, however, this usually indicates the performance of the factory state, if installed dozens of domestic APP, the situation may change - the fluency is significantly reduced, the user began to call the card.

Android application development has four components. Broadcast Receiver (BroadcastReceiver, hereinafter referred to as Receiver) is one of them. It is used to receive broadcasts from systems and applications. You can also understand that it is a listener, for example, when the power changes. The system will generate a broadcast. When receiving this broadcast, it can inform the user to save the progress or enter the power-saving mode when the battery is low. When a call comes in, a broadcast will also be generated, and the call will be notified or the phone number will be judged. .

A variety of systems Receiver (collected in ROM Toolbox)

In Android, there are nearly 100 kinds of Receiver in the world, which can monitor various state changes, such as power on/off, power-off, network status change, power change, installation and uninstall application, incoming call, SD card change, etc. Open Android allows applications to register any Receiver, which has become a breeding ground for rogue applications. Poor developers register multiple static Receivers with the system, accept various broadcast notifications, and then execute the corresponding activities, such as self-starting.

The main reason why Android uses more and more cards is that there are a lot of applications running silently in the background, and these applications are simply not cleaned up. They will start again after receiving various Receiver notifications. I can think of the best. The description is "the wildfire is not burning, the spring breeze is born again." In contrast, the method of restarting the background process that is killed in iOS is very limited. Simply put, iOS can really clean up the memory, and many applications in Android are lingering, constantly reborn, various processes and services in the background. Sneaking up, causing the system to stumble and consume power. In fact, how many developers will use electricity?

The rebirth of Android bad applications, there are two main ways: self-starting and associated wake-up.

Self-starting: It may be in our mind that it is equal to booting automatically, but it is not bad under Windows, but under Android you are too small, it is only one of many self-starting modes. In Windows, after you turn off a certain software, it basically won't start itself. Then Android has the advantage of Receiver, making self-starting easy.

Associative wake-up: The association wakes up a lot of people, and it is also a product with Chinese characteristics. Simply put, when an application is launched, it will secretly launch another application in the background. Basically, these applications have a nepotism. The infamous Baidu Department and the Ali Department are the representatives. It is true that the words "playing the tiger brothers and fighting the father and son soldiers".

Android smart TV is more and more use card solution:

1. Try not to install smart TV applications with very low frequency of use. Only the best ones of the same type of application are installed;

2. Try not to install third-party applications that are circulated on the Internet. Applications that do not confirm security are usually rogue;

3, install excellent Android system maintenance tools - such as the sofa butler application market (providing safe and reliable applications, as well as memory cleaning and other functions);

Why do Android Smart TVs use more and more cards, I hope you can find the answer from this article. The insufficiency of the Android system is now insignificant. The main reason is the confusion caused by openness. The bad behavior of domestic APP (various self-starting, related wake-up) has become the culprits of using more and more cards. Through the above solutions, Minimize negative effects and make your smart TV reproduce smoothly and smoothly. Optimize your smart TV regularly and let it run smoothly.
