2024 Brief Guide For You To Optimize Android App Performance
I. The Beginning
In today’s competitive app market, it’s important to optimize Android apps to run smoothly by optimising Android app performance. A well-optimized app not only works better for users, but it also stands out in the Google Play Store, where there are so many others. People are more likely to keep an app, use it often, and tell others about it if it is quick, prompt, and useful.
Performance optimization in Android changes many things about an app, from how fast it loads and how much memory it uses to how well it works with networks and how quick it is overall. By making sure your app works perfectly, you can make users happier, get more good reviews, and eventually make your app more successful.
This blog post will talk about some of the best ways to make Android apps run faster and better so they meet users’ high standards.
II. Shrink the app
One way to Optimize Android apps, to work better is to make them smaller. It’s better to have smaller apps because they run faster and take up less space on users’ devices.
Get rid of resources and libraries that aren’t being used
As you work on your app, it’s easy to get tools and resources that you no longer need. These could be images, layouts, or third-party tools that are no longer needed but were useful in the past. Regularly checking your app’s tools and getting rid of anything that isn’t needed can make it a lot smaller.
Reduce the size of pictures and other media files
Images and other video files often take up a lot of space in an app. By managing these files you can optimize Android app performance. It is possible to make these files smaller without losing quality by shrinking them. You can do this with the help of tools like WebP for pictures and new video types. This step not only makes the app smaller but also helps it start faster and run more smoothly.
Get rid of unused code and shrink the APK file size with ProGuard
The strong tool ProGuard (or R8, which came after it) shrinks, hides, and speeds up the code in your app. ProGuard can help you make your APK smaller by getting rid of classes and methods that aren’t being used. A smaller APK means that it gets and installs faster, which makes the experience better from the start.
III. Get better at managing memory
To get the most out of Android apps, you need to handle memory well. If you don’t handle your memory well, your computer may crash, run slowly, and be frustrating to use overall.
Use Data Structures and Algorithms That Work Well
Picking the right data structures and methods can have a big effect on how much memory is used. For example, when working with basic data types, it can be better to use a SparseArray instead of a HashMap to save space. Also, to make sure your app runs easily, always choose algorithms that are optimized for speed and memory use.
Cut down on object creation
Too many items can quickly use up memory, especially if they are big or complicated. Instead of always making new things, try to find ways to use things that you already have. This method not only uses less memory, but it also speeds up your app because making new items can use a lot of resources.
Use caching techniques to cut down on memory use
Caching is a powerful way to cut down on the number of times tasks that use a lot of memory are done. Your app can quickly get to data that is often used by saving it in memory and not having to reprocess or reload it. But be careful about how much data you cache, because too much caching can cause memory to use up quickly and systems to slow down.
IV. Make network calls better
Network calls often have a big effect on how well an app works, especially ones that send and receive a lot of data. To make sure your app is fast and quick, you need to make the most of the network.
Use HTTP/2 to send data more quickly
The speed at which data moves between your app and the computer is faster with HTTP/2, a new protocol. Multiple requests can be sent over a single link at the same time, which cuts down on latency and makes the network work better overall. You can make your app’s network tasks run faster by switching to HTTP/2.
Set up ways for network responses to be cached
Your app may not have to make as many requests if you store network replies. Your app can get data from the cache instead of making a new request if it stores answers locally. This saves time and bandwidth. This not only makes the app faster, but it also saves users’ data.
Combine calls to cut down on the number of network requests
When you can, combine several network calls into a single call. This cuts down on the extra work that comes with having multiple links and speeds up the data retrieval process. Say your app needs to load user data, profile information, and settings. Instead of making different calls, try to get all of this information at once.
V. Make Use of Multi-threading
Using multithreading will let your program run several operations concurrently, hence increasing its responsiveness and efficiency.
For background chores, use AsyncTask or RxJava
Background chores including file processing or data downloading should never be done on the main thread since they could cause the app to stop. Async Task or RxJava lets you do these chores in the background freeing the main thread for user interactions. This guarantees that your software stays responsive even during the intensive running of processes.
Use lazy loading for other resources including images
Particularly in cases involving big photos or resources, lazy loading is a good approach for maximizing app speed. Load resources just as they are needed rather than all at once. This lowers memory consumption and accelerates the first load time, so smoothes out the user experience.
Thread pools help you manage several chores
When handling several background chores, effective management is vital. Reusing threads for several tasks made possible by thread pools helps to lower the overhead involved in constantly producing and destroying threads. This enhances not only performance but also helps to properly manage resources.
VI. Track and Evaluate Performance.
Finding problems and possibilities for development in your app depends on routinely tracking and evaluating its performance.
Find performance challenges with Android Profiler
The Profiler of Android Studio is a complete tool designed to track in real-time the CPU use, memory allocation, and network activity of your application. Using the Profiler helps you identify particular locations where your program might be lagging and create focused fixes to raise general performance.
Track app performance with loggers and analytics
Using analytics and logging inside your software lets you monitor its performance in actual environments. Examining logs helps you spot trends suggesting performance problems including delayed loading times or memory leaks. By allowing you to better grasp user interaction with your app, analytics tools can also point up areas that could require work.
For in-depth study, use Third-Party Tools including Firebase Performance Monitoring
One useful tool offering an in-depth understanding of the performance of your app is Firebase Performance Monitoring. It lets you monitor measures including UI responsiveness, network latency, and app startup time. Using these insights will help you to make data-driven decisions to maximize the performance of your app even further.
VII. Benchmark and Test:
Crucially important phases of the Android app performance optimization process are testing and benchmarking. They guarantee that your app runs across many devices and conditions and help you assess the success of your improvements.
Test Performance on Many Devices and Network Conditions
From high-end cellphones to inexpensive models, performance testing should be conducted on a variety of devices to guarantee constant performance all around. To find how your program handles other network conditions, such as limited bandwidth or high latency, also replicate them. This will enable you to spot any problems and maximize Android app performance.
Use Memory Profiler and CPU Profiler included in Android Studio
Excellent tools for evaluating the performance of your app are the CPU and memory profilers available from Android Studio. While the Memory Profiler provides insights on memory use and any leaks, the CPU Profiler helps you know how much processing capability your app is consuming. These instruments will help you to guarantee that your app is responsive and efficient.
Compare the Android app performance both before and after optimization
Benchmarking is comparing the performance of your app both before and following improvements. This approach lets you measure the effects of your adjustments and guarantee they are improving things. Reliable data on the performance enhancements of your app will enable tools like Benchmark and Jetpack Benchmark assist you automate this process.
VIII. Final Thought
Optimizing Android app performance is a continual process including careful planning, testing, and iterating. Following the ideas presented in this article will help your app run much better, thereby improving user experience and increasing app market success.
Recall that optimization of performance is an ongoing endeavour rather than a one-time chore.
