Keep Your App Bug Free

Would you like shopping or ordering your food on an app that frequently crashes, lands you on the home screen, creeps like a snail, or just gets stuck in a rut? What would you do if the app halts right after you click on the “proceed to pay”? Let us guess you will stop using the app or even abandon the app altogether and pick out a competitor instead. Right? Simple because no one enjoys looking at a frozen screen or loading circle that calls for restarting the device, do you?

There are numerous such use cases to exhibit the possibilities of the mobile app crashing because it’s nearly impossible to develop a bug-free mobile app. One of the recent incidents is when iOS users reported Spotify, PUBG Mobile, Tinder, and other mobile apps were crashing down. The reason was stated to be Facebook’s SDK that these apps use to manage user logins.

It concludes: even though a mobile app development company builds a bug-free app, it can yet crash if the technology or an API integrated into the development misbehaves. Sometimes updates in such APIs and operating systems also cause your app to collapse. It can bring adversity to app data security, network connectivity, screen resolution, login/registration, etcetera. Nevertheless, the eventual solution to keep your app bug free is to follow rigorous testing and debugging procedures.

Let’s have a look at some more common app crashing causes before diving into the ideal debugging practices.

Common Often Appearing Bugs In Mobile App

App crashing after or repeatedly tapping on a button

One of the common bugs found in every other mobile app due to hidden buttons. Remember a time bomb that blasts off if you press its trigger? The same scenario occurs if you overlook a button and hit it. The action is like you activated a trigger that results in the application wrecks.

Showing the result repeatedly

When you scroll, an element reuses the previous element’s view and displays the same data on the screen. It often happens in Android specifically, based on how “ListView” works on Android, and it’s quite common as well.

Page layout resolution

It’s a QA job to ensure the application works perfectly and looks good on every screen of different devices. Given that, devices come in various operating systems, sizes, and resolutions. Lacking into this matter can lead to app interface elements split or worse when switching to landscape mode on your device.

No error handling

It can be considered a blunder, not to show or display an incorrect error message caused by a bad connection to the server. It lands users in confusion about what to do to make the application work again. However, be careful not to reveal important information that is useful for programmers but not to users.

Progress indicator

Operations like file uploading, profile editing, payment processing may take a longer time to be completed. Here, if the application doesn’t indicate any progress status, a user might think nothing has happened and click the same button multiple times. Clicking a button several times can sometimes create a severe issue, especially during online payment.

Significant Practices To Keep Your App Bug-free

Code Reviewing

Code revision is one of the most crucial practices to keep it clean. Reviewing your code from other developers can help you recognize issues or mistakes snuck by you. Even if you have skipped anything in the middle, a technical person with a fresh outlook can catch it quickly.

Besides, a veteran programmer has once said, “The best and most bug-free code is the code that you don't write." It advises to keep an app simple and use the method to code only what is necessary. Of course, you won’t like to build a product that creates more problems than it solves. Would you?

Beta Testing - Why?

User acceptance or beta testing is when you release a nearly end-version of the product for targeted end-users. Users judge product performance in the real world and provide their thoughts on the same. Suppose users with different operating systems report an issue in installing; it helps app developers find and work on the bug quickly.

You can run such testing repeatedly in order to find more relevant improvement areas or bugs. Just be sure that your beta version encompasses the necessary functionalities users can interact with.

Optimized Automated Test To Build A Bug-free Mobile Application

Adequate and periodic testing is paramount for keeping your app bug-free all the time. When it comes to testing programming interfaces, user interfaces, and app modules, automated tests are the best. It doesn’t require intense tester quality. Using the assistance of scripts, tools, and frameworks, and predefined actions, you can perform efficient testing.

Work On Error Reports

Take into account what kind of problems your end-users are experiencing during the beta testing before resolving them. Not every user will reach out to you to report the issues they found. Hence, use automated error reporting techniques to execute testing effectively and receive error reports. Besides, automated testing tools you use also provide error reports. You can now sit down and work on the error reports you receive and make an app bug-free.

Leverage Virtual Machines

An app has to undergo numerous testing, unit testing, beta testing, and automated testing to identify the problems. Moreover, a bug-free application needs to be tested in various environments and multiple OSs. Testing your app in Virtual machines is one of the innovative and less time-consuming ways of testing.

You can create standard-sized images and test them before uploading them on the server. For different operating systems, you just need to use base images without requiring the installation of the OS.

Pick A Good Debugger Ide

Development with Python, Ruby, or PHP can make it challenging to debug. However, investing in debugging tools like Visual Studio type of IDE can result in quality end-product when the app development process ends. It will save you from changing code parts and neutralize the risk of your app development.

Alright, before wrapping up, let’s hook you up with a practical exercise.

Here is a short but considerable list of questions in terms of quality assurance of an app. You have to note them and ask your QA on your final product. Done? Let’s go!

Are all the functions of your application working correctly?

If the application functions well over targeted platforms?

Whether the correct outputs for data entry are in place?

Is there any vulnerability that could put users’ data at risk?

Can targeted users use the application conveniently?

Have you set messages for error handling?

Will the application support a large download?

Does it allow users to return to the place where they left off quickly?
