What are the 8 key features to improve the performance of your app?

App Performance for Android?

Implementing a great app depends upon which necessary key factors is developed while building the application. Because of unnecessary things which will degraded app performance at runtime. These some of factors to communicate your app’s performance. For example, users want apps that:

Start up quickly.

Respond quickly to user interaction.

Bugs and Crashes Free.

Minimum APK size, etc.

Let’s see what are the 8 key features to improve the performance of app:

1. Optimize for Battery life:

Battery life is the most important aspect of the mobile user experience. A device without power offers no functionality at all. For this reason, it is critically important that apps be as respectful of battery life as possible.

2. Reduce the APK size:

Users often avoid downloading apps that seem too large, Allow new users to download your application. they first prefer what is APK size to download the app.beacuse of memory management is performs the big role in low memory devices. In India, low memory devices are used on a large scale.

3. Manage your app’s memory:

Random-access memory (RAM) is a valuable resource in any software development environment, but it’s even more valuable on a mobile operating system where physical memory is often constrained. Although both the Android Runtime (ART) and Dalvik virtual machine perform routine garbage collection, this does not mean you can ignore when and where your app allocates and releases memory.

You still need to avoid introducing memory leaks, usually caused by holding onto object references in static member variables and release any reference object at the appropriate time as defined by lifecycle callbacks.

4. Design for Seamlessness:

Even if your application is fast and responsive, certain design decisions can still cause problems for users because of unplanned interactions with other applications or dialogs, accidental loss of data, blocking, and so on.

To avoid these problems, it helps to understand the context in which your applications run and the system interactions that can affect your application. In short, you should make to develop an application that interacts seamlessly with the system and with other applications.

5. Keeping your app Responsive:

It’s possible to write code that wins every performance test in the world, but still feels sluggish, hang or freeze for significant periods, or take too long to process input. The worst thing that can happen to your app’s responsiveness is an “Application Not Responding” (ANR) dialog.

In Android, the system guards against applications that are insufficiently responsive for a period of time by displaying a dialog that says your app has stopped responding.

6. Avoid creating unnecessary Objects:

A generational garbage collector with per-thread allocation pools for temporary objects can make allocation cheaper, but allocating memory is always more expensive than not allocating memory.

As you allocate more objects in your app, you will force a periodic garbage collection, creating like degraded user experience.

7. Prefer static, over virtual Objects:

If you don’t need to access an object’s fields, make your method static. Invocations will be about 15%-20% faster. It’s also good practice because you can tell from the method signature that calling the method can’t alter the object’s state.

8. Remove unwanted Dependencies (Libraries):

If we use selective and necessary dependency will directly relate to memory management and it keeps much faster to read data. so remove unused dependencies and use only those dependencies which are important.

Conclusion:

To improve the application performance try to generate limited amount code and reusable functions to maintain data size. Also use relative functions, tools or plugins if necessary. else remove not used functions and irrelevant code to boost up app performance.
