This article shows you what are the ten key points to improve the performance of Android application development. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Although Android smartphones and tablets are getting faster every day, developers must keep in mind that the applications they develop are still running in a resource-strapped environment that relies mainly on batteries and processors that can't match the performance of desktop or laptop computers. Here are some ways to help your application "slim down" or "Android Top Ten points to improve development performance" so that they run best on today's and tomorrow's Android devices.

Let's start with a few programming points to ensure that your application responds quickly.

The first point: first of all, you must have good programming habits

To be a good resource manager, use common sense as well as accepted algorithms and standard design patterns. In terms of resource usage, if you open a resource, remember to close it. Get it as late as possible and release as early as possible. These long-established programming guidelines also apply to your Android applications, especially if they use underlying device services.

For example, suppose you write an application that relies on location-based services. Don't start registering and getting location information unless you absolutely have to, and make sure that once you no longer need it, unregister for it. This will help you avoid unnecessary consumption of the device's battery or system resources.

The second point: keep blocking operations away from the main user interface thread

To make sure your application runs flexibly, use AsyncTask, threading, IntentService, or custom background services to handle dirty work. Loaders should be used to simplify state management of long-loaded data, such as cursors. You cannot tolerate a lag or pause in your application when an operation is being processed.

If an operation takes a lot of time and resources, uninstall it and process it asynchronously so that your application remains responsive and users can handle their transactions. This principle applies to the following operations: read and write to disk, access to content providers, databases and the Internet, and parsing and other long-term tasks.

The third point: use the Android Software Development Kit (SDK) version, application programming interface (API) and * practice

Make sure that the application you develop is *, so use the * tools provided by the Android platform. As the Android platform continues to evolve, it also continues to improve. Some features may have been abandoned or replaced with better features. The core API has been revised (bug fix) and performance improved. New API such as loaders have been introduced to help developers write applications that run more stably and respond more quickly.

Did you know that hardware acceleration in Android3.0 applications can be enabled? Let's use it! Understand that practices change over time. Wise developers keep a close eye on the new features of the Android platform and which features are no longer recommended.

Fourth point: consider using restricted mode (Strict Mode)

You can use an AndroidAPI called restricted Mode (StrictMode) to help you find out where several good programming habits have been violated. StrictMode will help you verify that your application has memory leaks and detect if your application is trying to perform prolonged blocking operations that should be unloaded to threads or other channels (see second point).

The StrictMode class (android.os.StrictMode) is introduced into Android2.3.

Fifth point: disable or minimize debugging and diagnostics before releasing the application

If your Android application takes some time to develop, you may have embedded some logging and debugging code into the application. Writing to logs and other such output systems has an impact on performance. Be sure to use as little or disable these features as possible before releasing the application.

Now let's talk about how to use good user interface design principles to make your application's screen load faster:

The sixth point: make sure your layout is simple, concise and shallow.

A simple screen helps make it easiest to read, while a simple layout is the fastest to load. You should not nest your layout too deeply or fill the screen with unnecessary View controls. Take the time to develop a concise user interface that users can use efficiently, rather than trying to cram too many features into a single screen. This not only helps improve the performance of your application, but also helps to make your application more efficient for users.

Fragments helps to divide user interface functions without affecting the flexibility of designing for different types of devices.

The seventh point: adapt the resources of your application to the target device

Add resources that are appropriate for specific device configurations so that they can be loaded as efficiently as possible. This is particularly important when we talk about graphics resources. If you add a large number of available image resources that need to be loaded and resized, you will not be able to use other application resources effectively.

Another important point is that if you are prepared that your application can run on many devices, in order to keep the application package files of a reasonable size, you should initially add only the core resources needed to run the application, and then let the application download the content appropriate to the device.

Eighth point: use the Hierarchy Viewer tool

The Hierarchy Viewer tool can help you debug your application layout. It also provides valuable analytical information to understand how long it takes for each view control in the layout to measure, render, and draw. Only when the root cause of the problem is accurately found, can the problem be solved easily.

Ninth point: use 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 layout resources to minimize the use of resources. It allows you to know which layout controls may be redundant or unnecessary. The fewer controls and the shallower the layout, the better the performance.

Tenth point: use Traceview and other Android tools for analysis

Android SDK comes with many tools that can be used to analyze your application. Perhaps one of the tools is Traceview, a graphical tool that can help you debug and find performance bottlenecks in your application. Take a look at some of the debugging tools described in the Android documentation.

There are many ways to help you improve the performance of your Android application. Some need to use specific algorithms, while others rely on practical debugging and performance monitoring techniques. Fortunately, the Android platform comes with many free utilities that can help you identify and eliminate performance problems in your applications. Now that you have these tools, you should use them immediately!
