This article focuses on "how to improve the speed of Android applications", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how Android improves the speed of applications".

Do not let the UI thread wait

One of the most basic principles is not to perform time-consuming operations in the user interface thread. If you do so, the user interface will be locked (the interface is stuck) before the operation is completed, which brings a bad user experience. If it takes too long, the system deletes the thread or prompts the user whether to abort the operation.

If you do some work (business operations) in a UI thread, it's a pile of rubbish no matter how smoothly your code executes.

Second, time-consuming operation

What are the time-consuming operations? The most common is the network connection operation, the network state varies greatly with the change of the environment, the speed of the good part of the network may be very fast, but the poor part of the network needs to wait a long time, so you must not perform the network operation in the UI thread. In addition, there are database operations and SD card file read and write operations, these operations should not be completed in the UI thread, for database operations, we can build some indexes to improve the speed of the program.

Simulators and real equipment

There is also a big difference between the simulator and the real device, the simulator needs better CPU, if your computer performance is poor, you will feel that the running speed is very slow, but if you run on the real device will be very fast, in addition, the simulator uses the system hard disk, the access speed will be much faster than the real device access SD card.

IV. Notify the user

When you need to wait, be sure to use a progress bar to tell the user that the program is still running. Don't let the user interface get stuck. Using some animations that are being loaded will give users a better experience.

At this point, I believe you have a deeper understanding of "how Android improves the speed of applications". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
