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

We need to adopt the operational rules and standard design patterns that have been accepted by users. These long-Used programming rules also apply 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 build some debugging code in Android application development. 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!

10 Android app performance tips for developers

Lauren Darcey & Shane conder

As any mobile platform evolves and Its Application offerings improve, quality becomes paramount to success. These days, users demand responsiveness and reasonable performance from the android applications they choose
To install on their devices. And if those applications fail to deliver both exciting functionality and a stable user experience, then the application is quickly uninstalled.

Although Android smartphones and tablets are getting faster every day, developers need to remember that their applications are still running in a resource-constrained environment powered primarily by battery and processors
That do not rival the latest release tops or laptops. Here are some ways to slim down your applications so they run optimally on the Android devices of today and tomorrow.

Let's start with some coding tips for responsive applications.

Android app performance Tip #1: start with good coding practices

Be a good steward and use common sense, well-established algorithms and standard design patterns. resource-wise, if you open it, close it. acquire late, release early. these long-standing coding mantras apply to your
Android applications as well, especially if they use underlying device services.

For example, let's say you 've written an application that relies upon location-based services. don't start register for location updates until you absolutely have to, and make sure you un-register for updates as soon
As you no longer need the information. This will help you not drain the device battery or hog the system unnecessarily.

Android app performance Tip #2: keep blocking operations off the main UI thread

Keep your applications nimble by using an asynctask, thread, intentservice, or custom background service to do the dirty work. Use loaders to simplify state management of long loading data, such as cursors. You cannot
Afford for your application to lag or freeze while some processing is going on.

If an operation takes time and resources, offload that processing and perform it asynchronously so that your application remains responsive and the user can go about their business. This applies to operations such
As: reading and writing to disk, accessing content providers, databases and the Internet, as well as parsing and Other lengthy tasks.

Android app performance Tip #3: Use the latest Android SDK versions, APIs and best practices

Keep your applications up-to-date and using the latest that the Android platform has to offer. as the Android platform evolves, it is improved. some features may be retired, or replaced with better options. core APIs
Receive bug fixes and performance improvements. New APIs like loaders have been introduced to help developers write more stable and responsive applications.

Did you know you can enable hardware acceleration in your android 3.0 apps? Do it! Understand that best practices change over time. smart developers stay on top of what's new in the platform and what's no longer recommended.

Android app performance Tip #4: Check out strict Mode

You can use an android API called strictmode to help you track down violations in several good coding practices. strictmode will help you identify if your application is leaking memory, as well as detect whether or
Not your application is trying to perform lengthy blocking operations that shoshould be offloaded to threads or otherwise (see #2 ).

The strictmode class (Android. OS. strictmode) was introduced in Android 2.3.

Android app performance Tip #5: Disable or minimize debugging and diagnostics prior to publication

If your Android Application has taken more than a few minutes to develop, you 've probably got some logging and debugging code built into your application. Writing to logs and other such output comes at a performance
Hit. Make sure these features are minimized or completely disabled prior to release.

Now let's talk about how to make your application screens Load faster with good user interface design principles:

Android app performance Tip #6: Keep your layouts simple, elegant, and shallow

Simple screens make for the easiest reading and simple layouts load the fastest. You don't have want to nest your layouts too deeply or clutter your screens with more view controls than absolutely necessary. Spend
Time to develop elegant user interfaces that users can use effectively instead of trying to cram too much functionality onto a single screen. not only will this help application performance, but it will help make your application more efficient for users.

Fragments can help compartmentalize User Interface functionality without sacrifle icing flexibility for designing for different types of devices.

Android app performance Tip #7: tailor your application resources to your target devices

Include resources that are tailored to specific device deployments, so that they load as efficiently as possible. This is especially important when we're re talking about graphics resources. If you include huge drawable
Image resources that require loading and resizing, you're not using alternative application resources extends tively.

Another trick? To keep your application package file reasonably sized when targeting implements devices, only include core resources needed to run the application initially, then have the application download content tailored
To the device.

Android app performance Tip #8: Use the hierarchy Viewer tool

The hierarchy Viewer tool helps you debug your application layouts. It also provides valuable profiling information about how long it takes each view control within a layout to measure, render, and draw. Pinpoint
Problem areas and fix them easily.

Android app performance Tip #9: Use the layoutopt Tool

The layoutopt tool is a simple command-line tool that can help you identify unnecessary nesting of controls and other ways to collapse your layout resources to make them as slim as possible. It will give you hints
On what layout controls may be redundant or unnecessary. fewer controls and shallower layouts perform better.

And finally... So you think your app is the best it can be? Now it's time to put it to the test.

Android app performance Tip #10: Use traceview and Other Android tools for profiling

The android SDK comes with a number of tools for profiling your applications. Perhaps the most popular tool is traceview, a graphical tool that can help you debug and find performance bottlenecks in your apps. Check
Out some debugging tools discussed in the android documentation.

Conclusion

There are always ways to speed up the performance of your android applications. Some involve using specific algorithms and others rely upon tried and true debugging and performance monitoring techniques. Luckily,
Android platform comes with numerous free utilities to help track down and eradicate performance problems within your applications. You 've got' em, now use 'em! (Source:
