Due to the massive market share that the mobile operating system now holds, businesses that are creating mobile apps typically focus on the Android platform. Its success is due to the open-source nature of the platform and the regular addition of new features and updates.

Android devices often differ even when they are running on the same version of the Android OS due to differences in mobile hardware. Thus, it is essential that developers build mobile apps that can target a wide range of mobile devices running different Android OS versions while building Android apps, asw ell as focus on android performance optimization. 

Android application performance metrics

Why does android optimize apps? To optimize performance, you must first understand where exactly it fails. Optimizing apps, performance metrics help to find locations where the software wastes resources including the CPU, network, memory, and battery on the device, etc. There are a few things that every developer needs to pay attention to even without measurement, but first things first. 

Any application must have mobile app metrics. The most crucial KPIs for measuring the effectiveness of an application are:

  • its load time, 
  • crash statistics, 
  • and device details like operating systems and screen resolutions. 

These indicators give you the ability to manage the technical performance of your app and enhance the android app optimization testing procedure.

Load time

To store temporary data, your app can use the hardware’s cache memory. The mobile app will load more quickly as a result. The software uses cache data to speed up response times each time a user accesses it. Every time a user clears their cache, this procedure might need to be repeated to improve the load time performance and other services.

The optimal website load time should be no longer than 2 seconds, although it might vary depending on the hosting server, amount of bandwidth used in transit, webpage design, page elements, browser, and device type. The same’s with an app.

Time in app

Time in app is an additional metric for figuring out how frequently and enthusiastically consumers use your program. This engagement indicator measures behavior over time to offer you a clear picture of usage patterns and trends, much like session length and interval do.

Crash statistics

Crash stats or crash rates serves to track users that haven’t encountered any app bugs, malfunctions, or crashes during a specific period of time. These users are known as crash-free users. One day, an app might experience 21 opens and 3 crashes, for instance. You would not want a crash rate of 14%, which is what this would give you. Fewer than 1% per user, fewer than 0.1% each session, and less than 0.01% every screen view are generally considered to be the best app crash rates. In the very low range of 1-2%, the average crash rate for mobile applications shows that 98% of the remaining users are crash-free ones.

Device details

Device Info is intuitive and effective Android software that provides you with comprehensive information about your mobile device. To understand how the app consumes device resources, real-time statistics are provided via the Android Profiler tools, for example. In Android Studio, a number of profiling tools are provided to help with the discovery and visualization of potential problems:

  • CPU profiler: This tool aids in locating problems with runtime performance.
  • Memory profiler: This instrument helps in monitoring memory allocations.
  • The network profiler is a tool for monitoring network traffic.
  • Energy profiler: This device keeps track of energy usage, etc.

These and similar android optimizing app tools help to find and eliminate many Android performance challenges and beyond.

Android performance challenges

The process of creating high-quality Android apps is not without difficulties. Developers frequently deal with various challenges, from assuring compatibility with a wide range of devices to enhancing performance and managing security issues. Let’s examine some of the most typical Android app performance difficulties encountered when creating Android apps and consider solutions.


Android has a large selection of devices with various screen sizes, resolutions, and operating system versions, in contrast to iOS, which only supports a few devices and operating system versions. It can be difficult to create an app that functions flawlessly on all Android devices.

Besides, Google releases a number of Android applications every year with varied new features and enhancements. These most recent iterations of Android, however, are only compatible with some Android devices and are still lagging in terms of acceptability. As an illustration, Android 6.0 Marshmallow currently has a bigger market share than Android 7.0 Nougat and Android 8.0 Oreo.

As a result, when creating mobile apps, developers must consider Android apps that function with all Android operating system versions. Making the app utilize the features provided by both the most recent and older versions of the Android operating system is sometimes a challenge for them.

Computer Languages

Developers have access to a wide choice of programming languages that they can employ to make a variety of mobile apps. The most popular programming languages for creating Android apps among these are Java and Kotlin.

Despite being the most ancient programming language, Java requires more lines of code than Kotlin does. Both languages have features that make it simpler and quicker to produce mobile apps free of errors. Thus, one more typical difficulty for creators of mobile apps is deciding which one to start with.

Kotlin is a more recent programming language compared to Java, which is more widely used. Java is a straightforward language that uses a lot of storage and code. It works well with both native and cross-platform apps and speeds up app development. Java is the language used to write Android, so developers may use it to build apps, etc.


Incorporating external APIs is a task. It presents yet another difficulty for app developers working on Android applications. The time and money spent developing mobile apps will be reduced with the use of APIs. Developers can use third-party APIs to enhance the requirements for app compatibility.

APIs are used to streamline the app development process. This is so that work that satisfies company goals can be produced using APIs. By utilizing APIs, apps will be able to obtain the authentication and functions they require.

However, adding more APIs is a challenging procedure. On the other hand, Android developers can define a single API compatible with all Android versions. The process of creating user-friendly software is challenging for developers.

App performance Android

It’s essential to optimize app performance to deliver a seamless user experience. However, because of the memory leaks, wasteful resource utilization, and sluggish network connections, Android apps frequently experience performance concerns.

Designing a user interface (UI)

The process of developing user-friendly and efficient mobile apps is complex. The top mobile app development companies also face a difficulty in creating mobile apps that benefit from advancing technologies.

Any Android app must have an engaging and user-friendly interface to succeed. However, creating user interfaces (UIs) that function well in various screen sizes with different resolutions can be time-consuming and is a challenge.

Experts can only access a few features if they choose a customized user interface. They must follow certain requirements. Since Google hasn’t yet revealed any common UI (user interface) design guidelines or methodology for mobile app developers, the majority of developers don’t adhere to any standard UI (user interface) development principles or practices.

Only an app with a well-thought-out user interface will work with a range of gadgets. Therefore, choosing the best app development company necessitates thorough research.

Many apps function and seem differently across platforms because developers construct distinctive UI interfaces in their preferred ways. The complexity and inconsistency of the UI commonly affect the direct user experience of the Android app.


Android’s significant global market share makes it particularly susceptible to targeted security threats. Google frequently releases security patches and upgrades to fix security weaknesses in the core Android operating system. There are too many security flaws as a result of device manufacturers’ changes to standard Android, though.

It’s essential to have strong security measures in place because Android apps often handle sensitive consumer data. But Android is frequently the target of malicious assaults, which presents a big security challenge for developers. 

Due to its openness and significant market dominance, Android is frequently the target of cyberattacks. Despite its security precautions, there is still a chance that virus will infiltrate programs and reroute users to other URLs without the designers’ consent. Developers should therefore take all necessary steps to produce a secure program. But this is the most difficult aspect.

Compatibility with apps

Compatibility problems arise while ensuring app compatibility across various Android versions, screen sizes, and hardware configurations.

Memory Control

Due to the memory restrictions on Android smartphones, memory management issues can cause app crashes and subpar performance.

Debugging and Testing

A high-quality Android app requires extensive testing and efficient debugging. Finding and correcting faults while testing on numerous devices can be difficult and time-consuming. 

Testers must use several testing approaches at various times because every device has its own testing environment. Even if there are test automation tools that do testing automatically, testing approaches depend on the design of an app that app developers create.

Developers must test the user interface’s effectiveness, the code’s efficiency, the device’s computability, and other elements. It requires in-depth expertise with testing and debugging tools.

Android app performance optimization best practices

A developer faces many difficulties during the creation of an Android app in order to make it successful. However, Android app developers’ difficulties can differ depending on the mobile app. Each developer must use a particular mobile app development methodology in order to recognize and address these significant problems in Android app development and apply the best android app performance optimization practices to make it work.


How to optimize apps? Start with the research. Conduct in-depth market research to determine the most popular devices and OS versions used by your target audience. Utilize technologies like Android Virtual Devices (AVDs) and cloud-based testing services to test your app across a range of devices and configurations. Update your app frequently to support new Android releases and retire dated features to reduce fragmentation.

Track performance

Apply performance metrics, use effective coding techniques, such as proper data structures, algorithm optimization, and memory leak reduction. To locate and address performance bottlenecks, make use of performance profiling tools like Android Profiler and DDMS. Reduce the number of calls, compress the data, and use caching techniques to optimize network queries.

Test your app thoroughly, including load testing, to ensure it operates effectively in various situations.

Search memory leaks

To find memory leaks and excessive use, use memory profiling tools like Android Profiler. Avoid keeping a lot of information in memory. To load data quickly, employ strategies like pagination and lazy loading. Utilize the right compression methods and caching technologies to optimize the processing of images and resources. Use the trash collector wisely and dispose of items correctly.

Adhere to the Material Design UI design principles

To maintain uniformity and familiarity, adhere to Android’s Material Design UI design principles.

Create adaptive user interfaces (UIs) that adapt to different screen sizes by using responsive layout approaches like ConstraintLayout. To find and address any UI flaws, test your app across a variety of platforms. Use user feedback and ongoing usability testing to optimize your app’s user interface.

Encrypt the data

Sensitive data should be encrypted both during transmission and storage. Utilize reliable authentication methods, such as OAuth or biometrics. Update dependencies and libraries frequently to fix security flaws. Protect your app’s source code using code obfuscation and other security measures. To find and address any vulnerabilities, conduct routine security audits and penetration tests.

Provide extensive testing

Carry out extensive testing on multiple hardware, operating system, and configuration combinations. To support earlier OS versions, use Android’s backward compatibility support libraries. Update your app frequently to take advantage of new features and optimizations in more recent Android versions.

Develop a thorough testing plan that includes UI, integration, and unit testing. To speed up the testing process, use automated testing frameworks like Espresso or Robolectric, etc. Use crash reporting tools like Firebase Crashlytics or similar to find and fix app crashes. Encourage user feedback and think about starting a beta testing program to get information from actual users.

Optimize Images and Videos

Use responsive design and adaptive layouts to efficiently manage various screen sizes. Make sure your app adjusts to various screen sizes and resolutions by using responsive design strategies and optimising your visuals.

Reduce apps size

Uploading your software as an Android software Bundle, a new format which includes all of your app’s compiled code and resources and delays APK building and signing to Google Play, is the simplest approach to immediately reduce the size of your program when publishing to Google Play.


Android Studio provides tools for profiling to track and calculate memory allocations for your app.  Today it’s all about auto-packing (autoboxing) and unboxing. Boxing and unboxing automatically. To automatically convert between primitive type values and type-wrapper objects, Java offers boxing and unpacking conversions.

Autoboxing is the Java compiler’s automatic conversion between the primitive types and their corresponding object wrapper classes. For example, converting an int to an Integer, a double to a Double, and so on. If the conversion goes the other way, this is called unboxing.

This is one of the significant changes introduced in JDK 5. Developers can now write cleaner code, but not understanding how this mechanism works can lead to poor performance. So, learning the practice principles to apply it utmost is a way to improve apps performance.

Use string builder

Java’s StringBuilder class is used to build mutable, or otherwise changeable, strings of characters. The Java Strings class offers an immutable string of characters; similarly to StringBuffer, the StringBuilder class offers an alternative android optimizing apps slow.

How to check Android app speed?

The top Android speed test applications are listed below. You may apply any of at least these three tools to test the apps speed:


Fast, independent speed test tool Meteor by OpenSignal provides accurate performance tests with a beautiful user interface. Not only is it free and accessible on both iOS and Android, but it also describes your internet speed in clear, straightforward language.

SpeedTest Master

A potent speed test app available for iOS and Android is called SpeedTest Master. It provides a plethora of capabilities in addition to basic speed tests, such as the ability to gauge the ping response time for social media platforms like YouTube, PlayStation Network, Steam, and TikTok.

Speedtest by Ookla

Additionally, the software keeps track of your past performance, has a built-in VPN, and can provide a map of the state of your cellular network. However, Tom’s Guide hasn’t independently examined the reliability and efficiency of Ookla’s VPN.
