The Android App Bundle (AAB) is an innovative app publishing format introduced by Google to enhance the development, distribution, and user experience of Android applications. Unlike traditional APKs (Android Package Kits), which are directly installed on user devices, the App Bundle is a more efficient .aab file that contains all necessary resources, assets, and code. Google Play processes this bundle to generate optimized APKs tailored to individual devices, ensuring a smaller app size and improved delivery efficiency.
Think of the App Bundle as a dynamic and modular container that allows developers to streamline app building while providing users with a customized, lightweight experience.
1. Dynamic Delivery
App Bundles utilize Google Play’s Dynamic Delivery system, ensuring that users only download the necessary resources for their specific device configurations, such as screen density, CPU architecture, and language packs. This eliminates unnecessary bloat, making app downloads faster and more efficient.
2. On-Demand Features
With Dynamic Feature Modules, developers can provide optional features that users can install later instead of bundling everything at once. This reduces the initial download size, enhances flexibility, and improves the overall user experience by allowing users to personalize their app features.
3. Smaller App Size
By excluding unnecessary resources, App Bundles significantly reduce the app’s overall size. This is especially beneficial for users with limited storage capacity as they no longer need to download assets that are irrelevant to their device. Reduced app size also improves installation speed and performance.
4. Google-Managed App Signing
Google Play manages the signing of APKs generated from the App Bundle, ensuring security and seamless updates. This eliminates the need for developers to manually handle key management, reducing the risk of key loss or compromise and ensuring app integrity.
5. Backward Compatibility
App Bundles are compatible with devices running Android Lollipop (API level 21) and above. This means developers can adopt the AAB format without worrying about excluding users with older Android versions, making it a flexible solution for app distribution.
The Android App Bundle leverages Google Play’s Dynamic Delivery system to generate and distribute optimized APKs specific to each user’s device. This eliminates unnecessary data, reducing app size and enhancing performance.
1. Split APK Mechanism
The App Bundle acts as a container file (.aab) that includes all app resources. Google Play then breaks it down into smaller modular APKs tailored for individual devices. Instead of downloading a large, universal APK, users receive only the parts necessary for their device.
Example:
2. Types of APKs Generated
a) Base APK
b) Configuration APKs
c) Dynamic Feature APKs
3. Dynamic Delivery by Google Play
4. Security & App Signing
5. Key Technologies Behind App Bundles
An Android App Bundle (.aab) is an upload format for Google Play that organizes app resources into modules. Google Play then generates multiple APKs based on this structure.
App Bundle’s Key Directories:
Unlike APKs, App Bundles cannot be directly installed on devices. Instead, developers upload a signed .aab file to Google Play, which then builds and signs APKs for distribution via Dynamic Delivery.
To generate and upload a signed app bundle:
Pcloudy supports the .aab format, allowing developers to upload and test their App Bundles on real devices in the cloud. This ensures smooth functionality before releasing the app to users, making it a crucial step in the testing phase.
The Android App Bundle is a game-changer for app development and distribution. By optimizing APKs for individual devices, reducing app size, and streamlining feature management, AAB improves the overall efficiency of Android app publishing. Developers benefit from simplified build management, while users enjoy faster downloads and reduced storage consumption, leading to higher app adoption rates.

The mobile market has seen exponential growth over the past decade, largely driven by the mobile application industry. With more than 3.5 billion smartphone users worldwide, mobile apps have become an integral part of our daily lives. This booming sector is expected to generate over $189 billion in revenue by 2020 through app stores and in-app advertising, and the demand shows no signs of slowing down. As mobile apps become more ubiquitous, the competition to create unique, high-performing apps has intensified.
Yet, as apps grow more complex and diverse, so do the challenges faced in ensuring their quality. Mobile app testing plays a pivotal role in meeting these challenges, especially as the industry evolves at a rapid pace. Below, we explore the common issues in mobile app testing and offer solutions to ensure apps remain competitive, reliable, and user-friendly.
One of the most significant challenges in mobile app testing is device fragmentation. With countless manufacturers, models, operating systems, and screen sizes, testing across all devices is a daunting task. Android alone has a wide range of OS versions, with older versions still in circulation despite new releases. This fragmentation means that an app may perform flawlessly on one device but crash on another.
Testing on a range of real devices is the best way to ensure compatibility. This is where cloud-based platforms like Pcloudy come in. Pcloudy offers access to real devices with varying OS versions and configurations, allowing testers to check how their app behaves across multiple devices without needing physical access to each one.
Pro Tip: It’s crucial to prioritize testing on the most popular devices and operating systems to maximize your app’s reach.
In today’s connected world, apps must perform well across a variety of network conditions. However, this introduces another layer of complexity in mobile app testing. Network issues, such as low bandwidth or weak signal strength, can drastically affect an app’s performance, leading to poor user experiences. According to studies, 53% of users will uninstall an app if it crashes, freezes, or has performance issues.
Testing apps under real-world network conditions is essential to ensure that they perform smoothly, even under poor network environments. Pcloudy offers network simulation tools that enable testers to replicate varying network conditions, from weak 2G signals to high-speed 5G or Wi-Fi, on real devices.
Pro Tip: Regularly test your app’s performance in low-bandwidth scenarios to ensure seamless user experiences in all conditions.
The choice of testing tools can significantly impact the efficiency and effectiveness of mobile app testing. There are numerous tools available in the market, each with its strengths and weaknesses. Selecting the right one based on your app type (native, hybrid, or web) and testing needs is critical.
To navigate this landscape, it’s crucial to evaluate tools based on your specific app requirements. Pcloudy supports a wide range of automation tools, such as Appium, Espresso, and Selenium, making it easier for teams to test apps across multiple environments.
Consider the following when evaluating tools:
Mobile devices come in various screen sizes, and ensuring that your app displays correctly on all of them can be challenging. Apps that look perfect on a large-screen phone may appear cluttered or disjointed on a smaller device.
Adopt responsive design principles to create adaptable UI layouts. This approach ensures that your app looks good on all screen sizes, from small smartphones to large tablets. Testing your app on real devices of varying screen sizes is crucial, and platforms like Pcloudy allow for testing on multiple screen configurations to ensure a seamless experience.
Pro Tip: Focus on adaptive designs rather than pixel-perfect layouts, as adaptive designs scale more effectively across different screen sizes.
Mobile apps come in three main forms: native, hybrid, and web-based apps. Each type requires a unique approach to testing.
Each app type comes with its own set of testing challenges, and it’s essential to customize your testing strategy accordingly. Pcloudy supports testing for all three app types, allowing teams to ensure that their apps meet the required standards of performance, usability, and functionality.
Artificial intelligence is revolutionizing mobile app testing by automating complex testing tasks, generating test cases, and predicting defects. AI-driven testing can significantly reduce time and effort, allowing testers to focus on more critical aspects of app development.
AI-powered test automation, like the solutions offered by Pcloudy, helps automate repetitive tasks such as regression testing, bug detection, and performance analysis. AI-driven bots can create test cases, execute tests, and analyze results, enabling faster releases and higher accuracy.
Pro Tip: Embrace AI-based testing early to stay ahead of the competition. Automating repetitive tests frees up resources for more creative problem-solving.
In an era where data privacy and security are of paramount importance, ensuring that your app is secure and compliant with regulations is vital. The increasing number of cyberattacks and data breaches highlights the need for robust security testing.
Incorporate security and compliance testing into your QA process. Test for data encryption, authentication, and security vulnerabilities. Pcloudy offers features like biometric authentication testing and encrypted device communication to ensure that your app meets the highest security standards.
Pro Tip: Regularly update your app’s security protocols to keep up with emerging threats and regulations.
Usability testing focuses on how user-friendly your app is, evaluating its ease of navigation, intuitive design, and overall user experience.
Conduct usability testing on real devices to gather feedback from real users. Cloud-based platforms like Pcloudy allow for real-device usability testing, providing insights into the app’s user experience across different devices and operating systems.
Battery consumption is a critical factor that can impact app usage and customer retention. An app that drains battery quickly is likely to be uninstalled by users.
Test for battery efficiency on various devices using real-device cloud testing environments like Pcloudy. Analyze how your app consumes battery power and optimize where needed to ensure it runs smoothly without excessive battery drain.
Memory leaks occur when an app uses excessive memory, causing performance issues like slowdowns or crashes. This can lead to a poor user experience, especially on devices with limited resources.
Implement memory profiling tools during your app’s development and testing phases. Regularly test your app on different devices using Pcloudy to identify and fix memory leaks.
For apps that rely on geolocation features, such as navigation or ride-hailing apps, ensuring that location services work across different regions is crucial.
Use cloud platforms like Pcloudy to simulate geolocation testing on real devices in different geographic regions. This ensures your app’s location services work accurately across the globe.
Apps often need to be localized to different languages, currencies, and cultural contexts. Ensuring proper localization is essential for expanding into global markets.
Conduct thorough localization testing, focusing on the user interface, translations, and regional features. Pcloudy allows testing in real-world scenarios for apps localized into multiple languages and regions.
Accessibility testing ensures that your app is usable by people with disabilities, such as visual or hearing impairments. Ensuring your app meets accessibility standards is vital for inclusivity and can be a regulatory requirement in many regions.
Use accessibility testing tools to check your app’s compatibility with screen readers, voice commands, and other assistive technologies. Test your app on different devices using Pcloudy to ensure it meets accessibility guidelines.
Interruption testing evaluates how well an app handles interruptions like phone calls, text messages, or low battery alerts. These interruptions are common during real-world app usage.
Perform interruption testing on real devices to evaluate how your app reacts to common disruptions. Cloud platforms like Pcloudy allow testers to replicate interruptions during active app sessions, ensuring smooth recovery and minimal disruption.
Each app store (Google Play, Apple App Store) has specific guidelines for app submission. Failing to comply with these guidelines can result in rejection, delaying your app’s release.
Before submitting your app, ensure it meets all necessary guidelines. Test your app’s experience, security, and overall quality on multiple devices and operating systems using Pcloudy to minimize the risk of rejection.
Mobile app testing involves overcoming a wide range of challenges, from ensuring compatibility across numerous devices to handling network variability, memory leaks, and accessibility. A successful testing strategy combines real-device testing, cloud-based automation, AI-driven test automation, and comprehensive security testing to deliver a high-quality app experience.
Pcloudy provides a robust cloud-based platform for mobile app testing, offering access to real devices, network simulation, and AI-powered automation. By adopting a well-rounded approach to testing, you can ensure
Android uses a centralized system for all logs and application programmers can also write custom log messages. The tooling to develop Android applications allows you to define filters for the log statements you are interested in. Log analysis is a phase of development and developers encounter it from time to time. Bug log helps in identifying the bugs in the Android application while in the development phase. Once the app is released into the market, the support engineers analyze the bug logs to resolve the issue. There are for different types of Logs available in the Android Eco-System – Application Logs, Android System Logs, Event Logs & Radio Logs.
The logging system consists of a kernel driver and kernel buffers for storing Android log messages, C, C++ and Java classes for making log entries and for accessing the log messages, a standalone program for viewing log messages (logcat) and the ability to view and filter the log messages from the host machine (via eclipse or ddms).
There are four different log buffers in the Linux kernel, which provide logging for different parts of the system. Access to the different buffers is via device nodes in the file system, in /dev/log. The four Android log buffers are main, events, radio and system. The main log is for the application, events is for system event information, radio is for phone related information and system is low level system messages and debugging.
Each message in the log consists of a tag indicating the part of the system or application that the message came from, a timestamp (at what time this message came), the message log level (or priority of the event represented by the message) and the log message itself (detail description of error or exception or information etc).
What Each Android Log Type Contains:
1. Application log use android.util.Log class methods to write messages of different priority into the log Java classes declare their tag statically as a string, which they pass to the log method The log method used indicates the message “severity” (or log level) Messages can be filtered by tag or priority when the logs are processed by retrieval tools (logcat)
2. System log Use the android.util.Slog class to write message with different priority with its associated messages Many Android framework classes utilize the system log to keep their messages separate from (possibly noisy) application log messages A formatted message is delivered through the C/C++ library down to the kernel driver, which stores the message in the appropriate buffer(system buffer)
3. Event log Event logs messages are created using android.util.EventLog class, which create binary-formatted log messages. Log entries consist of binary tag codes, followed by binary parameters. The message tag codes are stored on the system at: /system/etc/event-log-tags. Each message has the string for the log message, as well as codes indicating the values associated with (stored with) that entry.
4. Radio log Used for radio and phone (modem) related information Log entries consist of binary tags code and message for Network info Logging system automatically routes messages with specific tags into the radio buffer
Device Logs on pCloudy Platform.
Log format on Android A common log format in android:
tv_sectv_nsec priority pidtid tag messageLen Message
tag: log tag tv_sec&tv_nsec: the timestamp of the log messages pid: the process id of where log messages come from tid: the thread id Priority value is one of the following character values, ordered from lowest to highest priority:
V — Verbose (lowest priority)* D — Debug* I — Info* W — Warning* E — Error* F — Fatal* S — Silent (highest priority, on which nothing is ever printed)
Log-File locations There are several directories where Android log (including those from crashes) stores and it are not standardized (i.e. some may be ROM-specific). I am putting some of common here. /data/anr : Dalvik writes stack traces here on ANR, i.e. “Application Not Responding” aka “Force-Close” /data/dontpanic : contains some crash logs including traces /data/kernelpanics :- Stores “kernel panic” related logs /data/tombstones :- may hold several tombstone_nn files (nn is a number from 0 to 10 and after 10 again repeat it)
‘Log’ command line tool To capture Android log from the devices/emulator Below is the some command line tool. In real life project there are log capture application/tool used to capture the logs on user device and shared it back to Developer/maintainer for analysis . adb logcat (shows all type logs for current android system adb logcat -v threadtime (it will include date and time) adb logcat -v threadtime> logfile.txt (Store logs in logfile.txt)
Useful filter patterns You can use below filter in your adb command to filter logs. You can also use this filter to search your logs file(Android logs provided by user device). adb logcat -f Save all logs into a file adb logcat “*:E” Get all errors and fatals adb logcat | grep -i “foo.example.” #get all logs related to “foo.example.*” tagname adb logcat “application_or_tag_name:*” “*:S” Get all logs by application name adb logcat -b events “gsm_service_state_change” “*:S” Get all GSM state changes adb logcat -b radio Get all Radio events
Log Analysis In this blog we got the basic understanding of the Android Log System. While analyzing the Android logs from your app you can divide it in two parts, debug Logs – file coming during development and testing phase and production Log – file coming directly from end user. The best way to do it is by using useful Filter Patterns and by using Some Tool like GoogleLogTool and SonyLogTool.

AndroidX is an improved version of the android support libraries that the android team uses to develop, test, package, version and release libraries within the jetpack. AndroidX fully replaces the support library by providing feature parity and new libraries. In addition, AndroidX includes the following features:
Android Jetpack Android jetpack is a set of components and tools along with architecture guidance designed to help you accelerate your android development. It gives a template to write production ready android code. Jetpack is made up of components in four categories, foundation architecture behaviour and UI. Each component is individually adaptable and build to maintain backwards compatibility. Android architecture components are very modular, so we are allowed to choose what feature sets we want that are compatible to our app. Espresso is now a part of the AndroidX family Espresso is a testing framework designed to provide a fluent API for writing concise and reliable UI test. Writing reliable UI test is difficult as user interfaces are asynchronous driven by events, transitions and data loaded from background threats. Coding around that without any help from UI testing framework would require a lot of boilerplate. Espresso takes care of any UI events, so that in most cases you don’t have to worry about any view state transition and implementation details. The basic UI test flow when using Espresso includes:
Application of Espresso test recorder
Pcloudy supports androidX instrumentation with Espresso Now you can write test cases in espresso and test the APIs in pCloudy using androidX Junit instrumentation. Here are the steps for running your Test scripts on multiple android devices:
Note: pCloudy provides support for Instrumentation Type (InstrumentationTestRunner, AndroidJUnitRunner and AndroidXJUnitRunner) for Android.
To migrate from support libraries to AndroidX the Google has provided a refractor tool in Android Studio. Projects can be migrated to AndroidX by clicking on ‘Refractor’ in the menu bar and then clicking on ‘Refactor to AndroidX’. Then it will search for the usage and show the result. To refactor click ‘Do Refactor’. pCloudy is leading the way in the field of automated mobile testing solutions. Try our device cloud

Android now occupies the number one place in the world Smartphone arena with a market share of 87% at the end of 2016 that means 9 out of 10 Smartphones in the world run on Android. With such dominance in the space, the creation of mobile apps has reached never before heights. But the constant innovation that fuels this market has major problems in terms of the development and testing timelines. Running an online Android emulator, which used to be a solution once up a time, is not good enough anymore. So what can companies and developers do to stay ahead in the development race? What alternates exist to improve your app’s usability, performance and customer satisfaction? Let us explore.
With the explosion of Smartphones, customers’ screen size is reducing. People are moving from desktops and laptops to Smartphones for their everyday work and personal needs. This massive shift from big screens to a personal device has created a huge opportunity for developers to create tools that can help people with their work and their personal needs. Users can now view their spreadsheets and book movie tickets from their phones.

Apple’s Appstore and Android Play store has become the ‘go to’ place for people to discover apps that meet their requirements. The ratings left on those apps will decide how many people will install those apps. Customers have once again become the king of the market.
Days of unique apps are over. For your every need you will find at least two or more apps, giving you a choice. So if you want people to choose your app, install it, use and positively review it, your app needs to user-friendly, work on most handsets and be bug-free.
In the past, companies and developers determined product lifecycle. They planned the updates, feature upgrades etc based on the resources and other factors. Today the scenario is changed. The Market dictates the timeline. If your app is incompatible with the latest OS, or not render properly, or suck a lot of battery juice, off it goes into oblivion to be replaced by a better app.
The fight for the screen space is constant.
You can win the fight only if you develop faster than others, test it better and offer a good user experience. That means developers will need to compress their development cycle and testers should speed up their testing while at the same time, maintain high usability and reliability of the app.
Android and iPhone both offer an easy to use platform for developers. iPhone has a few products (IP6, IP7, IP8 etc.) and versions (OS 8, OS9, OS10 etc). The permutation of devices and OS makes testing with real devices easier although buying that many Apple devices is quite an expensive investment. You don’t need an online emulator while testing for iPhone.
In contrast, Android has a highly fragmented market. Apart from different versions (KitKat, Jellybean etc), there are different forks of Android (Stock, Cyanogen, OxygenOS etc) and there are also different skins that manufacturers put on their devices (TouchWiz, Optimus, Sense etc). Real android device testing to cover all the combinations is close to impossible and quite expensive.
Enter Online Android Emulators
When they started, online Android emulators were like a boon to developers. They could cross test their apps across different devices without physically buying the phones. Most of the Android emulators were easy to set up and a fairly inexpensive solution. Most importantly, online Android emulators could mimic hardware and software behaviour making easy for developers to identify unexpected behaviour during the early stage testing.
But as the market for apps grew, the demands on the app became even higher. Testing all the features of the app on an Online Android Emulators was not providing the full picture of how the app would behave on a customer’s phone.
For example, a user installs a new app on the phone and the next day he notices the battery is getting low very fast. Looking at the battery usage, he discovers the culprit is the new app and bam! He hits uninstall. He then visits the Playstore and writes a negative review of the app’s battery-sucking problem. The next 20 people who see that review will not install the app.
These kinds of bugs cannot be easily identified using an online android emulator. Apart from that, online emulators are slow because they have to replicate both software and the hardware components. thus slowing down the whole testing cycle.
Online android mobile emulator stimulate android devices on a PC to test an app on a variety of devices and API levels without the need for physical devices. Nox is the best online android emulator although BlueStacks is the best android emulator for online games. Online android emulators come with predefined configurations for various Android phone, tablet, Wear OS, and Android TV devices. There are many online android emulators for iOS available in the market.
Online Android emulators also have other limitations that make them unsuitable for large-scale testing. There are a limited number of OS versions you can run on an Android emulator. Even on a good PC with HAXM acceleration support, you can run approximately 8 emulators at a time. Even if you manage to set up all the online emulators you need, one small problem can send the whole system crashing forcing you to start all over again.
So what can app developers do to speed up their product lifecycle while releasing a relatively bug-free app? Is there any alternative for Online Android Emulators?
Testing on real devices has a few important benefits. Your testing can be in real conditions i.e. weather, location network accessibility, interruptions like SMS, calls etc can be tested accurately. You can also validate the screen brightness, visibility in different lighting conditions. Testing on a real device will be a lot faster than on an Android emulator.
The biggest problem in using actual android phones is the cost of buying all the phones you need to test. There are approximately 11k Android phone models in the market making it financially impossible to test on all available Android devices. This is one reason Online Android Emulators became famous in the initial stages.
You can run only one test at a time. If you have staff in another city or country, they cannot access the device. If you need to install an app, you have to do it manually on every device. Apart from that, there is also a question of logistics, maintaining the devices, updating them, etc all of which are time-consuming tasks.
One tactic used earlier involved a combination of using online Android emulators during the early stages and a small selected list of real Android devices during the beta testing. While this would work for a localized team, it still does not optimize device usage and covers a tiny portion of devices while the fragmentation continues. Thus it is not an optimal solution.
Is there a third alternative that can beat the disadvantages of online android emulator and real devices testing? In recent times, a new mode of testing is gaining popularity among both amateurs as well as professional developers. It is called Mobile cloud testing.
What is Mobile cloud testing?
Testing on real devices using the cloud as the Interface is the new way of balancing the real android testing while making it economical and scalable. As a developer, you need not own any phones or buy expensive software. You connect to a lab that has a huge selection of Smartphones, select the ones you want to test on and start, it is that simple. You can run functional tests, automated tests, performance and other forms of tests easily. Since the interface is cloud-based, you can test from anywhere in the world, at any time.
There will be some changes in the way you set up your test, install an app, etc. All the testing though will happen on actual devices under user-level conditions. You can set the location, observe CPU utilization, battery drainage and pretty much anything else that you can do with a device in your hand. These are the things you can never test with an online Android emulator.
The best part is that you need not invest in any special infrastructure for such a facility. There are independent services providers who can allow you access to the device on a cost per use basis. You can even reserve devices in advance if you want to plan a battery of test over an extended period.
Opting for mobile cloud testing service gives you access to real devices at a fraction of a cost of setting up your own lab. There are no recurring charges as most of them use a ‘pay as you go’ model. You can spend all your time in testing rather than worry about the infrastructure, maintenance and other problems that come from the ‘owning’ model.
While there may not be a cost associated with getting Android emulators, they need a lot of expensive hardware to run a sufficient number of an online android emulator. Mobile cloud testing does not have a problem.
Using Mobile cloud testing, you can cover more ground over a large number of devices than if you were using either only real android device testing or the online android emulator. For example, if you have 10k scenarios to cover, you can spread it over 1k devices through automation rather than 1k test scenarios over 100 different online android emulator.
One of the biggest benefits of testing mobiles over the cloud is that you are more likely to discover bugs that affect real-world customers than what an emulator can reveal. From a user satisfaction perspective, this is probably one of the biggest advantages mobile cloud testing has over online android emulator.
Most of the app development work has moved to the agile methodology which means testing will run almost parallel to development work. You will need a way to speed up the testing process to meet the sprint deadlines.
Using a mobile cloud, it is easy to streamline the testing process whether you are using a DevOps or an agile approach. Continuous testing is a lot easier to streamline over the cloud setup rather than via online Android emulators or even with real devices.
Many development teams are spread across the globe. Cloud setup gives them an easy way to test seamlessly from different geographies.
Security for Mobile apps testing
Different apps have different needs in terms of security. An Astrology app that gives general predictions may have little data security requirements while a banking app might need the testing to be done in a secure environment. Such clients can always go for a private cloud or even opt for on-premises setup. When you use a good solution provider, you can just hook up your existing devices to their setup and give access to your cross-border teams to test on the devices.
Testing performance issues, be it CPU load, battery discharge or performance over 2G, 3G and other networks work a lot easier when you use the mobile testing via the cloud platform. You can select which network mode you want to be on and apply the test. This kind of flexibility is difficult and sometimes, impossible using an android emulator.
Mobile Apps Performance Testing
Apart from the need to test for compatibility with existing apps, battery usage, network usage etc, and mobile apps will need to go through a round of performance testing. Due to the ever-increasing storage space in a Smartphone, users tend to store a lot of content on their phones. So it is necessary to find how the increase in storage affects the application performance.
For example, if you are developing a photo gallery, how does your app perform when accessing 5 GBs worth of pictures and videos, v/s accessing 50 GBs worth of pictures and videos? Does it slow the pre-fetch? Customers are very unforgiving of apps that slow down their phones.
In case your app has a server-side component, it is important you run a performance test to verify how many concurrent users the server can handle. There have been many instances where e-commerce sites crashed being unable to keep up with increased demands during holiday sales.
These are a few areas that we cannot test on an online android emulator.
A customer kept waiting is a customer lost
A couple of years ago, it was acceptable to wait for two-three minutes to download an image on a phone. But today if your app takes longer than few seconds to start up, it is killed and replaced. The tide has shifted to the customer’s side in the Appstore and Playstore. The only way to win this game is to be Nimble, easy to use and not crash the phone.
Thanks to Mobile cloud testing, you don’t have to wait for the slow, unreliable online Android Emulators anymore. Testing on Mobile cloud gives you the opportunity to cut your infrastructure cost, speed up your testing cycle, spread your testing over a larger set of devices and gives you close to real-world results. As the completion heats up for the screen space, you have one tool in your kit that can help your app survive the tough jungle of user reviews.
