Tips On How To Improve App Performance in Android

While developing the android app, its performance is the most important aspect. Your users uninstall your app if your app performance is poor. The more effectively it performs, the higher the chance of market success. If you’re wondering how to improve app performance in android, you’ve come to the correct place.  


Tips to Improve Application Speed


How to improve app performance in android


1. Reduce the Size of The App

This is the most important point in our tips on how to improve app performance in android because the GPUs in smartphones are not yet that strong. A positive innovation is that most of the worldwide Android market share is taken up by minimally equipped smartphones. Although some of them don’t support 2G or 3G, users often avoid installing large programs, especially when they’re in a rush. Therefore, it is preferable for users if it takes up less space on their phones.


2. Image and Video Optimizations

A lot of photos and videos are loaded by your Android app besides APIs. Other properties, such as your app’s website, usually load those photos as well. Images and videos on desktop webpages differ from those on mobile applications in terms of resolution, screen size, and device kind. As a result, you need to carefully allocate your app’s resources to optimize your photos and videos for mobile devices. When your Android app requests photos, make sure they are of the highest quality and resolution. You may also use adaptive video buffering and progressive images to allow your app to download images sequentially rather than waiting for the entire image to download. Make sure users will not see a blurred image because of the reduction.


3. Improve Offline Mode

If your network connection is poor, try to display whatever data is available while fetching the essential data. Regarding usability and performance, we would strongly advise you to show information in offline mode. If you don’t employ caching, you could experience terrible user experiences since data recovery takes a long time because of a bad network.


4. Reduce the App Launch Time

According to Google, 70% of mobile app users uninstall an app if it takes too long to load. Furthermore, the top 25 apps on the Play Store launch in 800 ms to 4.5s. Users always desire an app that is quick and responsive. If your app takes too long to load, users will probably have a terrible experience and leave a negative review on the Play Store. Read 


5. Using Threads Efficiently

On  ‌how to improve app performance in android, threads are the secret techniques to optimize an Android app. Developers that understand how to deal with threads efficiently may quickly create a reliable and high-performing program that resolves most performance issues. But first, ‌understand that there are two sorts of threads in an Android app: the primary (or UI) thread and the secondary (or background) thread. Any modifications you make to the UI thread will affect the main thread. And, using the FIFO method, you can’t allocate the continuing work to another call or method until it’s completed.


6. Instead of String, Use StringBuilder

Because string concatenation requires many garbage collection processes, this method may be expensive. On a good smartphone, it takes about 5 seconds to run. Despite that, it is time-consuming. Because strings are immutable and cannot be changed. So, if you want to update the value of a String, you’ll just create a new String with the required value.


7. Improve Networking

As a general rule, always prioritize text over an image. To optimize Android apps, load textual data first, followed by image-based content, which should be loaded asynchronously. As your app will use the internet to upload or download data, you must effectively handle network requests. Cellular data is one of these network requests, and the battery is another. Heavy use of mobile networks and WiFi drains the battery quickly.


8. Adjust Screen Size

Today, it is the most challenging thing for developers. Screen size created excitement. Because nowadays smartphones are available in various sizes and shapes. Your layout’s rigid dimensions will only respond to a specific orientation and screen size, so your app should support as many screens as possible. Make sure your layout accommodates different screen sizes and aspect ratios so that a wider range of users can access your app from various devices.


9. Boost Memory Usage

Android has provided RAM to the users for multitasking‌. Your app will have limited RAM availability, which may change depending on how it is used. Such Android restrictions, along with other background apps, consume unnecessary resources. Memory is one of the most serious issues you must address. If you keep a reference to an unused activity in the code, you will keep the layout of the activity, including its views. This generates a few pixels that you do not want to keep in your memory. 


10. Get a Smooth Frame Rate

On both Android and iOS, the highest frame rate for rendering motions and animations is 60fps (frames per second). If your app runs slower, it will deliver a slowdown in android app performance, destroying the user experience. To achieve mobile app development frameworks to 60fps, execute everything in your app’s rendering code within 16ms.  You might think that a slightly lower frame rate, such as 58-59fps, will suffice, but the bad news is that if your app exceeds the 16ms limit, it will have to wait for the next one. But though rendering took only 19ms, it missed the window, forcing users to wait twice as long.


11. Determine the Latency Killers

Latency issues could be a major issue for your app. Latency can cause critical app errors and, in extreme cases, crash the entire app. 25% of mobile app users give up their app after only one use. So to successfully deal with latency issues: limit third-party latency sources and Cut down the requirement for latency killer APIs.



The world today depends on digital technology, and nos of android devices increased the vast speed. Users are paying attention more and more. The only way to keep them is to have a successful mobile app. With these tips, you may get the knowledge on how to improve app performance in android !!! When these techniques are used together, you can grow your business online with Android app development services.
