Top ten tips to quickly improve Android app development performance

Quality is critical for an application to be successful in development. Users are asking them to decide that Android applications installed on their devices respond quickly and with reasonable performance. If the application fails to provide useful functionality and a stable user experience, it will be uninstalled quickly. In this article we will introduce ten tricks to quickly improve Android app development performance.
1: First of all to have good programming habits
To be a good resource manager, use common sense and adopt well-known algorithms and standard design patterns. In terms of resource usage, if you open a resource, remember to close the resource. To get as late as possible, release as early as possible. These long-standing programming guidelines also apply to your Android applications, especially if they use the underlying device services.
2: Keep blocking operations away from the main user interface thread
To make sure your application is flexible to run, use Asynctask, threading, Intentservice, or custom background services to handle dirty work. You should use the loader to simplify state management for long-loading data, such as cursors. You cannot tolerate a lag or a pause in your application when an operation is being processed.
3: Use the latest Android software Development Kit (SDK) version, application programming Interface (API), and best practices
Make sure that the apps you develop are up to date and use the latest tools available on the Android platform. As the Android platform continues to evolve, it is constantly improving. Some features may have been deprecated or replaced with better functionality. The core API has been revised (bug fix) and performance improvements. New APIs, such as the loader, have been introduced to help developers write applications that run more stably and respond more quickly.
4: Consider using the restriction mode (Strict modes)
You can use the ANDROIDAPI called restricted mode (Strictmode) to help you find out where a few good programming habits have been violated. Strictmode will help you verify that your application has a memory leak and that your application is trying to perform a lengthy blocking operation that should be offloaded to threads or other channels.
5: Disable or minimize debugging and diagnostics before publishing the application
If your Android app takes some time to develop, you may have embedded some log and debug code in your application. Writing to logs and other such output systems has an impact on performance. Make sure that you minimize or completely disable these features before you publish your application.
6: Make sure you design a simple, concise and shallow layout
Simple screens help you to read the most easily, while simple layouts are the quickest to load. You should not nest your layouts too deeply, or fill the screen with unnecessarily excessive view controls. Instead of trying to plug too many features into a single screen, take the time to develop a streamlined user interface that users can use efficiently. This not only helps improve the performance of your application, it also helps make your application more efficient for users.
7: Make your application's resources fit the target device
Add resources that are appropriate for a specific device configuration so they can be loaded as efficiently as possible. This is especially important when we talk about graphical resources. If you add a large image resource that you can take advantage of, you will not be able to use other application resources efficiently by loading and resizing.
8: Using the Hierarchy Viewer tool
The Hierarchy Viewer tool can help you debug your application layout. It also provides valuable analysis information to understand how much time it takes to measure, render, and draw each view control within a layout. It is easy to solve the problem only if you find the root of the problem accurately.
9: Using the Layoutopt tool
The Layoutopt tool is a simple command-line tool that can help you find unnecessary nesting of controls and other ways to reduce your layout resources to minimize the use of resources. It allows you to understand which layout controls may be superfluous or unnecessary. The fewer controls, the lighter the layout hierarchy, the better performance.
Finally, the most critical step, it's time to test it.
10: Analyze with AI Beta and other Android tools
Love Beta is the most professional mobile applications in the domestic cloud service platform. Solve one-stop testing for app security, compatibility testing, bug management, network monitoring, plug-in evaluation, and more to help you detect and find performance bottlenecks in your applications. You may also want to look at some of the debugging tools described in the Android documentation.
