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.

Android Mobile Development

What is Play Store?

Play Store is a digital distribution service operated and developed by Google. It serves as the official app store for the Android operating system.

Play Store also called Marketplace. We can install any app on Play store on all android devices.  It acts as Store or Home of Official developed android apps by developers around the world.  Play Store provides a huge amount of Android apps available and we can access from anywhere using internet connection.

Play Store provides categories of apps to install on Android devices like Art & Design, Communication,  Education, Entertainment, Games, Health & Fitness, Maps & Navigation, Travel & Local, Finance, etc.

According to Google, the number of available applications in the Google Play Store from December 2009 to December 2017 is 3.5 million apps in December 2017, after surpassing 1 million apps in July 2013. As per Comparison, Apple’s App Store remained the second-largest app store with 2.2 million available apps.

Let’s see what are the ways in which Need of Android Application in Play Store and how empowers the app industry and positively affects the mobile application market:

Platform :

Google provides official Android App (Play Store) to the Android Developers and Android Users. The motto of the Play Store is android user can install a variety of apps from this platform and having free as well as paid apps.

Security:

Play Store provides Play Protect feature is an evolution of the Google’s “Verify Apps” service.  The feature, which will be enabled by default on all Android devices, is meant to be a real-time malware scanner that will scan every installed or about-to-be installed app and inform users in case there’s something amiss.

Popularity:

Millions of Android compatible state of the art application are available in play store. As per the analysis, Google’s Android Play Store is the Topmost app store in the world and the tough competitor to its Apple’s App Store is holds the second-largest position.

Conclusion:

Google provides its official Play Store and having security, reliability to choose millions of apps but many of the third-party apps are available on various websites which is not available in play store. The reason behind that these apps are Dangerous work via malicious advertising or even code. While not all third-party apps are “bad,” many stores bait users by offering popular apps for much cheaper prices and subsequently put user privacy very much at risk. Examples of sensitive information extracted through third-party app stores include phone numbers, device information, and email addresses.

So we can always prefer a security while using an Android device, Google provides more security day by day and Google having rights to ban suspicious and malicious apps available on play store.
