Sharing 10 tips to improve the running performance of Android apps

By Lauren Darcey & Shane conder

With the development of the mobile phone platform and the improvement of the provided applications, quality has become the most important factor for the success of applications. If those applications cannot provide powerful functions and stable user experience, they will soon be uninstalled by users. Developers need to remember that, although the speed of Android smartphones and tablets is increasing, their applications are still running in environments with limited resources, its battery and processor performance are still different from those of the latest desktop and laptop computers. The following are some methods to optimize the Running Effect of applications:

Let's first explain some programming skills that make the application responsive.

Tip 1: Start with excellent programming

Use the operation accepted by the userAlgorithmThese long-Used programming rules are also applicable to Android applications, especially when these applications use internal device services.

For example, assume that the application you write needs to be based on the geographic location service. You only need to start registration when necessary to update the location. When you do not need to update information, make sure that the application stops the update process. This helps reduce the power of the device and the burden on the system processor.

Tip 2: Keep the application flexible

Use asynctask, intentservice, or custom background services to maintain application flexibility. The loader is used to simplify the State management of data that has been loaded for a long time, such as the cursor. Applications cannot appear slow or completely static in other processes.

If some operations require a certain amount of time and resources, you should separate the process for asynchronous processing so that your application can run smoothly. Operations that can be performed in this way include disk read/write, access to content providers, databases, and networks, and other tasks that require a long period of time.

Tip 3: Use the latest Android SDK version and API

Keep the app updated and use the latest content provided by the Android platform. With the development of the Android platform, it is gradually improving. Some features are removed or replaced with better options. The vulnerability in its core API has been fixed, and the overall API performance has been improved. This platform has introduced new APIs such as loaders to help developers write more stable and responsive applications.

Android 3.0 Applications Support Hardware acceleration, which can be applied. It should be understood that the best performance will change over time. Wise developers will update the latest content and APIs released by the platform.

Tip 4: Check strict Mode

You can use the android API called "strictmode" to find programming problems. Strictmode helps you identify whether the application is consuming memory, or you can check whether the application is trying to perform long modular operations.

Strictmode is released in the same period as Android. OS. strictmode and Android 2.3.

Tip 5: Disable or minimize debugging and diagnosis before release

You may debug some Android applications.CodeBuild it. Ensure that these features are minimized or completely disabled before the application is released.

Next, let's discuss how to use excellent User Interface Design Principles to make your application load faster.

Tip 6: Keep the layout simple and natural

The concise and natural layout will speed up loading. Do not fill the screen layout with excessive unnecessary content. Spend some time developing simple user interfaces that users can effectively use. Do not put too much functional content into a single screen. This not only helps the application performance, but also helps users use the application more effectively.

The split content helps to divide User Interface functionality without sacrificing the flexibility of applications on different devices.

Tip 7: Adjust application resources based on the target device

Adjust resources based on specific device configurations so that they can be effectively loaded. This is especially important in terms of image resources. If your application has large image resources that need to be loaded, make adjustments.

Another trick is to keep the application package file size appropriate when targeting many devices. You only need to include the core resources required for running the application, then, let the user download other content of the application based on the specific device.

Tip 8: Use hierarchy Viewer

The hierarchy Viewer tool helps you remove vulnerabilities in the application layout. It also provides a lot of valuable information, such as how long each view takes to control. Find the domain to which the problem belongs, which makes it easier to solve the problem.

Tip 9: Use the layoutopt Tool

The layoutopt tool is a simple command line tool that helps you identify unnecessary controls and other things that make your layout resources crash and improve its performance. It helps you find unnecessary layout control. The application running performance can be optimized in a relatively small and shallow layout.

Finally, test the application when you think it is the best.

Tip 10: Use traceview and Other Android app compression tools

The android SDK has many tools that can compress applications. Traceview is probably the most popular tool. This image tool can help you debug and locate performance problems of applications.

Conclusion

There are currently many ways to accelerate the running of your Android app. Some involve some specific algorithm rules, others rely on some real debugging and Operation Supervision technologies. There are many free tools available on the Android platform to help track and adjust performance issues in applications. You have learned the above 10 skills and can try them now!
