Technique for Optimizing & Reducing the APK size of Android App

Today everyone hates running their phones out of space or having trouble while uploading their app on the App Store. So what is the problem behind this! Is your phone running low on memory or slow enough to execute the upload process? No! The real problem is with the application of larger sizes.

Certainly, Size has been affected by increasing the mobile storage space to 256 GB, mobile app size is also increasing as App Developers are starting to add the latest features to the app to meet the growing and changing needs and needs of the market. Furthermore, with the practice of supporting your apps on different screen sizes, the app size increases. As a result, the increasing number of features added to the app, the SDK, changes to higher resolution images, better graphics which makes the SDK size larger.

With all these facts, it becomes a situation for users, as if they cannot proceed with heavy apps on their screen, nor get rid of them. In addition, they remain in a love-and-hate relationship with these apps. On one hand, rich graphics, hassle-free navigation, a bundle of advanced features steal users’ hearts. On the other hand, these apps are crushing the huge size of their mobile storage space. According to the latest survey report, 74.4% of the world’s people use Android devices and 70% of users consider the size of the app before installing it on their device.

Effectiveness of APK size on Installation Conversion Rate

The Android package (APK) size server plays a major role in establishing the conversion rate. According to various studies and survey reports, it has been concluded that smaller APK sizes depend on higher conversion rates and conversely reflect translation. As most Mobile App Development companies are shifting their focus towards venturing into new emerging markets by adding some advanced features and functionalities to their app. But at the same time, it is important to be aware of increasing the size of your app.

App size is the Biggest Issue in the Mobile App Development Domain

If we look at Google’s figures and consider it, 84.8% of people using Android in 2020 are expected to jump to 85.7% in 2024 compared to 15.2% of iOS users in 2020. The global user base is 2.7 billion with access to 2.8 million applications in the Google Play Store. Adding to this, the SDK size and installation conversion rate are intimately correlated. According to Google, if the app size is more than 150 MB, installation is likely to be less than 30%. For every 6 MP expansion in application size, the installation conversion will be reduced by 1%.

Since the above data shows that the size of the APK badly affects the installation conversion rate, all Android app developers should be serious about this matter because 70% of the users are actually on the app’s size before installing it. Let’s consider. So while hiring a mobile app developer for your next project, keep in mind that there is no benefit to having an app that has no users.

Before we dig deeper to understand how to reduce the size of Android app during the development life cycle, it is worth understanding how the app size increases.

App size continues to grow & is becoming a cautious issue for Android developers

Indeed, modern day apps are stealing the show by adding an excellent level of correct management facility to everything from taps on your screen. But uncertainty, these apps are severely shaped for these three reasons:

  • Increasing number of feature sets.
  • Fast growing UX expectations.
  • Support for multiple platforms and different screen sizes.

Apart from affecting the storage capacity and memory of mobile devices, the most disappointing part about heavy apps is also the increase in data consumption. And this is the reason that is inspiring the users to uninstall the app. So, whether you are a leading brand trying to deliver an excellent user experience through an app, you need to emphasize on making smaller apps. Don’t worry, Google always has a way of dealing with these issues. It provides tools to develop to troubleshoot the problem. So let’s discuss how to reduce and reduce the size of Android apps.

Tips to reduce Android app size throughout development lifecycle

  • Optimize & Compress of Image Files

Browsing an app with high-resolution graphics is quite inspiring and interesting. But, be aware, heavy-sized images can slow down your app and increase the size of your app. So what to do if you want to optimize and reduce the image size without diluting the image resolution?

Basically, Images use two formats, either .jpeg or .png files. So whether you are going to compress the file on your own or hire an Android app developer for the same, there are many tools available for such conversions. Tools such as Guetzli and packjpg are recommended for .jpg file compression, while pngcrush and zopflipng support .png files.

  • Few More Option for Optimize & Reduce the Image Size

Designers can apply vector graphics to create simple resolution-independent images that do not have much space. It is available in Android as readily available objects that make it easier by allowing you to generate sharp and screen-size images under a 100-byte file. This can be a great idea for smaller size applications to reduce the size of the image

By adding this, developers can use the Draw 9-Patch tool or the WYSIWYG image editor, allowing you to create bitmap images and auto-resize to fit different screen sizes of different devices. To crunch the size of .png images, you can take advantage of the aapt tool, which is available in Res / drawable and allows you to shade the shape.

Eradication of Unutilized Process, Codes, Classes and Virtue

When developing a mobile app, it is common to have unusable code and resources in an unusable system. These codes are generated automatically and are not useful for the app at all, but they simply expand the app’s size rapidly. Since they do not add any value to your app, it makes sense to track them down and remove unnecessary code from your app immediately. And for this, you can benefit by using some tools and techniques, which we are talking about below:

  • RB Code Shrinker Tool

When it comes to reducing or shrinking app size, most software development companies usually leverage the knowledge of this tool. Code shrinking allows you to reduce the size of your APK by automatically removing unused code and resources from the system.

  • Eliminate your Code with ProGuard

Since R8 is comparatively new and still in a growing state, you may prefer to use ProGuard to remove unused classes, methods, fields, and attributes from your code until it becomes stable. Can. However, be careful when using ProGuard because sometimes it removes the code that your app needs to function. So you always have to test the functionality of your app first to publish it.

  • Scan your Codes with Android Lint

Lint is a static code scanning tool that cannot identify the necessary resources anywhere in your code. But the major issue with the use of lint is that it only identifies unused resources, and cannot remove these resources. So you will need to check its report and extract all the identified resources manually.

Elimination of Dead Codes

As the size of the APK file is directly in sync with the loading speed of the app, it devours the storage of your device, making it clear that it is powered by power. And will only add bulk to any unused and inactive code for your app. By removing extra and dead code, you can speed up your application without affecting the functionality of the app. By adding this, eliminating these codes helps you to upgrade the quality of the source code and reduce the need to maintain code size. Therefore, the scope of bugs in your application is prevented and allows you to introduce bug-free healthy apps.

Limitation the use of Resources from Libraries

It is common to use external libraries when developing Android applications to enhance the user experience and increase versatility in the app. And basic are Google Play services used primarily to recover auto translation of app text and Android support libraries that are used to enhance the user experience on dated devices.

Basically, the problem is that most of these libraries are designed for servers or desktops, so they come with heavy methods and objects and do not serve any purpose for your application. To reduce the size of the application, you can edit files and keep the parts that your app needs to function. But to make changes, you will need access to the modification. But the simple solution to this problem is to either hire an app developer or use a mobile-friendly library for specific functionalities.

Use Android Size Analyzer Plugin 

If you want to find out what exactly is in your app, you can either hire an App Development Company or take advantage of the Android Analyzer plugin to analyze every element of your app. It tries to help you with a lot of data about the size of the Android package. In fact, it is one of the easiest ways to determine and implement methods that will cause app size reduction and allow you to activate your app.

Use Android Pleasure Size with APK Analyzer, you can:

  • Understand the structure of DEX files.
  • See the correct size of files in the APK.
  • By accelerated view of the ending version of the files in the APK.
  • Compare two APKs simultaneously.

Now there are three ways to access this plugin during project development:

  • It is necessary to first drag an APK into Android Studio’s editor window.
  • Switch to project perspective in project window
  • First select the Build Analyze APK in the menu bar, and only then select your APK.

Key Questions to Ask Before Hiring a Mobile App Developer

Key Questions to Ask Before Hiring a Mobile App Developer

Perhaps the least surprising thing you’ll read today is that mobile app development is one of the fastest-growing industries in the world. Businesses ranging from startups to Fortune 500 companies recognize that apps are a must-have in 2019; the benefits are endless, such as boosting sales and user engagement. There’s no question that you should develop a mobile app for your business, but there are questions you should be asking a development agency before hiring them to create your app. 

  1. Can I see some of the mobile apps you’ve developed before?

Qualified developers should be excited to show you their portfolio and provide you with a list of apps they’re responsible for building. This is one of the best ways you can tell if you’ll get a good ROI.

  1. Can I speak with some of your clients?

Many agencies have profiles on review sites like Clutch, where you can read unbiased and verified accounts detailing mobile app development projects. Ask your candidates if you can speak to some of their past or present clients; this will give you invaluable insight into how the candidate performs and whether they have the experience necessary to understand your business model and customer base. 

  1. How skilled are your developers?

This may seem obvious, but make sure the agency’s developers have the skillsets necessary to build the features and functionalities you want on your app. Ask for links to the developers’ GitHub and LinkedIn accounts. 

  1. Do you follow coding standards and use a framework?

We highly recommend hiring an agency that uses web application frameworks, which are organized coding systems. If you ever need to bring the app to another agency, it could be hard for other developers to work on it without a framework in place. For example, most agencies use Bootstrap as a standard coding practice. Does the agency you’re considering use Bootstrap?

  1. Can you build apps for different operating systems?

Keep in mind that some developers specialize in coding for Android apps, while others only do iOS.

  1. How will you manage the development process?

The quality of your app depends on how effectively you relay your app design and functionality requirements, so make sure the candidate is open to frequent communication and feedback. Ask whether they use collaboration tools, such as Asana, Trello, or Jira, which allow you to see the developer’s progress in real-time. 

  1. How can I make money off my app?

If your main goal is to generate revenue, the developer will need to know how to build in features that will allow you to make money. 

  1. Who will own the mobile app? 

Typically, the individual or company paying for a mobile app will own the finished product. To be sure you own all of the rights to the app you commissioned, you and the developer should sign a written contract.
