One of the most pressing concerns for web page or web application developers is performance. No one will be pleased if an application “crashes” due to heavy demand, or if a page takes an eternity to load. Users are not willing to wait long for websites to load or for their pages to become operational. According to Kissmetrics, 47% of website visitors anticipate a page to load in under 2 seconds. If the site takes longer than 3 seconds to load, 40% of visitors will abandon it.
Android app development services by Fireart have prepared an article in which we will tell you about 5 ways to improve the performance of your android application.
1. Take use of browser caching techniques.
In browsers, there are two basic methods for caching data. The first method is to employ the JavaScript-API Cache, which is managed by service workers. The second option is to use a standard HTTP cache.
Access to certain items is frequently organized using scripts. You may increase the efficiency of your code by keeping a reference to an object that you regularly need to access in a variable, or by utilizing that variable in repetitive actions that need access to the object.
2. Make the code more suitable for the environments in which it will be used.
It is advised that a set of conditions be created in which measurements may be taken in order to properly evaluate the program’s progress.
In actuality, you won’t be able to undertake code performance studies in all available versions of JS engines, nor will you be able to optimize your code for all possible settings. It should be mentioned, however, that testing code in a single environment is also not a good idea. This method may produce erroneous findings. As a result, creating a set of settings in which the code is most likely to execute and testing projects in those contexts is critical.
3. Remove any JS code that is no longer in use.
Removing unneeded code from your project will improve not just the time it takes for browsers to read and compile code, but also the time it takes for browsers to load-scripts. You should pay attention to the project’s idiosyncrasies if you want to get rid of unneeded code. So, if you discover any functionality that people don’t utilize, consider deleting it from the project, as well as the JS code that goes with it. As a consequence, the site will load quicker and be ready for work in the browser more rapidly. This will improve the user experience when they interact with the site. Keep in mind while examining a project that a specific library contained in its composition may have been inserted by mistake. It’s possible that it won’t be utilized at all. It’s one of those things that’s worth getting rid of. The same can be said about relying on dependencies to implement features that are already available in current browsers. As a consequence, switching to normal browser functionalities that are replicated by this dependence will help you remove unwanted code.
4. Don’t rely on memory too much.
It is worthwhile to make every effort to ensure that online applications only consume the memory that they really require. The reality is that a developer cannot predict how much memory his program will have on a particular device. When an application utilizes a lot of memory unnecessarily, it puts a lot of strain on the browser JS engine’s memory management methods. This is especially true with the garbage collector. Calls to the garbage collector on a regular basis slow down programs. This has a detrimental impact on the project’s usability.
5. For supplementary scripts, use lazy loading techniques.
Web pages should load as rapidly as feasible for users. However, it’s doubtful that the entire project’s JS code is required for the page’s initial appearance. If the user must take any action (for example, click on an element or navigate to any tab in the application) before using a code, the loading of that code might be delayed by running it after the page and the most critical resources have loaded.
With this method, you can avoid the browser loading and compiling a big amount of JS code at the start of work, i.e., you can avoid the need to execute these actions slowing down the page output. After all of the necessities have been downloaded, you may begin downloading extra code. As a consequence, the user will already have this code when he needs it. Google suggests lazily loading scripts having a length of 50ms or less, as per the RAIL model. The code loading procedures will not affect the user’s interaction with the page if you utilize this method.
To Sum Up
Nothing kills your application faster than disgruntled users. In a rush during the development and launch stages, many teams forget about the main participant in the whole process – the user.
Therefore, it is especially important to pay special attention to ensuring that the end-user of your Android application is satisfied and gets positive results from using it again.
Starting to think like a user is a good way to improve the user experience, even though it sounds obvious. To do this effectively, it is not enough to simply think about how to arrange the buttons and functions in the most convenient way. You need to understand how the application will be used and how users will be attracted by it.
Maintaining a balance between code efficiency and readability is critical. The computer interprets the code, but it must be maintained by humans. As a result, the code must be comprehensible not just by computers but also by humans.
It’s also crucial to note that while performance is vital, it shouldn’t take precedence over having your code work smoothly and providing the application features that consumers want.
