Six Major Reasons Why Your App Crashes

Exploring Why Apps Crash. How to Avoid it - Promatics Technologies

In this day and age, you can not ignore the importance of smartphones and the kind of hold they have in our lives. Many people can not perform even some of the basic day-to-day functions without a smartphone. With this increased dependency comes a big responsibility for app developers to develop an app that runs seamlessly.

 

At least once in your life, you must have encountered the dialog “Unfortunately, Facebook has stopped working” or “Chrome has stopped working,” especially if you are an Android user. Well, whenever this popup appears and the app you are using closes unexpectedly and forcefully, that is what you call an app crash. The app does not specifically have to run in the foreground for it to crash. You might have been talking to a friend of yours on WhatsApp when Facebook, running in the background, crashed.

 

Give this article a thorough read to know all about the consequences, reasons, and remedies of app crashes.

Consequences of Continuous App Crashes:

If an app keeps crashing, it will negatively affect user experience and will gravely impact the app owner. Here are some consequences of an app crash:

 

a.) Poor reviews:

Nowadays, people are not as tolerant as they used to be. And why should they be when they experience an app that freezes and crashes now and then. They will let go of it the first time the app crashes. They might even ignore it the second time. But if the app crashes again, it is bound to get poor reviews and a bad rating on AppStore or Play Store. You might have come across several apps with a great user interface but get bashed in the rating department due to multiple crashes.

 

Poor ratings can hurt the app developer indirectly as well. When other people see those reviews and ratings, they feel hesitant to download the app. The level of reluctance is directly proportional to the number of such reviews. So not only does a user become discontented, but they also convince a potential customer not to download that app. As a result, your brand goals are affected, and your marketing expenses reach a sky-high level. If you ever get a lot of bad reviews on your app you should actively work towards reducing it.

 

b.) Uninstalls:

After giving a poor rating, the next step for an unsatisfied and disgruntled customer is to uninstall the app and delete it for good. Then, they will switch to one of the competitors, bolstering them and giving them a boost. Think of a big building that loses its bricks one by one. There will come a time when the whole building will come crashing to the ground. If you lose your customers one by one, your app will, like that building, collapse one day.

 

If you somehow manage to locate the source of the problem, you will have to release an update. So, if you save your customers and users from continuous bugs and crashes, you might lose them because of the never-ending updates. Moreover, this will also prove to be a financial burden by inflating development costs.

c.) Lost Transactions:

eCommerce apps have even more to lose due to an app crash. If the app freezes and eventually stops working during a transaction, it can interrupt or, in the worst-case scenario, lose the transaction. With each lost transaction, you lose revenue, your customer’s trust, and, ultimately, your customer.

Major Reasons for App Crash

Now that we have discussed how an app crash can impact both the developers and users let’s discuss the main reasons that cause an app to crash.

 

i.) Testing Issues:

One of the most common reasons for frequent app crashes is inadequate testing, especially on actual mobile devices. We have often seen it happen that a team releases their app without rigorous testing in real user conditions due to budget or time constraints. But, the bugs and app crashes lead to an increased strain on budget and time. For this reason, we believe that you can not release a reliable and stable app without adequately testing it on several mobile apps.

 

App developers and their teams sometimes do not have access to all types of mobile devices, which is why they may use a simulator for testing. Simulators or software running on a server is not an ideal choice, as these do not exhibit the same performance limitations as in real mobile devices. For instance, a fault in the code might result in one part trying to modify a part of the database while another trying to read it. This issue will not be highlighted on a simulator, so the quality of testing matters as well.

 

Remedy: The best way to deal with this problem is to practice continuous testing on a real device cloud. Additionally, developers can benchmark the app against user expectations and industry standards so that users know what the developers have in mind.

 

ii.) Problems with Memory Management:

If an app has some performance problems, it might be due to problems with memory management. The reason behind it is most developers do not pay much attention to or prioritize memory management. Suppose an app developer makes an app that soaks up a lot of the phone’s memory resources. Although this might not be a problem for phones with more RAM, performance and app crashes will be a big concern in extreme cases on other phones.

 

Let’s discuss this cause with an example. We all know that camels can store a lot of water, which is why their water requirements are not that high as compared to, say, lions. Now, in an ecosystem with plenty of water to offer, both camels and lions will survive. But in the desert, lions will struggle, while camels will manage.

 

Similarly, if an app is programmed to take up more memory, it will crash and fail to run on phones that have lesser RAM. Developers sometimes forget that only their app does not exist. The software has to be run on varying mobile devices that have to be considered too.

 

Remedy: As a developer, if you want most of your users to have an exceptional user experience, you will have to reduce your app’s memory usage and focus on better memory management.

 

iii.) Faulty Code:

The senior systems engineer at Lextech Global Services, an enterprise mobile development firm, once explained that the most bug-free and the best code is the one that you do not write. What Felipe Laso-Marsetti meant was that a lot of times, bugs and performance issues arise due to errors in the code. And no matter how hard you try, you will only be able to write an error-free code at the first attempt on the twelfth of never.

 

Programmers and developers have to think ahead and anticipate the errors. Otherwise, they face a null pointer or null reference, a term that developers use to call a reference or pointer that does not refer to a valid object. Some developers make their code public, making it accessible for anyone and everyone to make changes. Consequently, you might have to deal with changes made by random, third-party developers.

 

Remedy: Start from names and nomenclature if your code is too long and you are looking for areas to cut. Long names, with an even longer description, make the code larger and more complicated than it should be. Keeping additional functionalities and dependencies from exceeding more than needed can go a long way in helping you maintain a short, error-free code.

 

Major Reasons why Apps Crash

 

iv.) Inappropriate or Unstable Network Conditions:

With further development and advancement, and the implementation of a cloud networking system, the dependency of apps on a stable network connection has increased multifold. And for this reason, an app can continuously crash even if the developer has written a perfect and error-free code. Imagine using Instagram on your apartment’s WiFi, but suddenly, you have to head out. Your network will switch from WiFi to 3G once you walk out the door. But it will shift from 3G to 2G when you are in the elevator and back to 3G once you are out. A competent developer will anticipate these network changes and prepare for them while writing the code. But that is not always the case. Sometimes, a programmer might develop an app keeping in mind their stable internet connection. But one of the users may live in an area of bad reception and poor network connection. And that user will experience continuous app crashes and suffer from poor performance issues.

 

Remedy: While you check the software for any bugs, test how the app will respond and behave in various network connections and conditions. Or, if the issue is out of your hand, you could make the offline version of the app available to the user. Or, in the case of apps that require a consistent internet connection, you can program the front end to display the last loaded version.

 

v.) Complications due to Front-End Optimization:

Most of the time, the back-end is responsible, and the major source of app crashes, but not in all cases. Another reason that causes apps to crash is poor front-end optimization. Some of the media might load without any interruptions on the developer’s setup. But that does not mean that the same will happen for all the users as well. Poor media optimization often messes things up and causes the app to run inconsistently, eventually resulting in a crash.

 

Remedy: There are various image optimization tools to help you out with this issue.

 

vi.) Bandwidth Constraints:

Another factor influencing your app stability is bandwidth constraints. A bandwidth constraint is triggered when an app running in the background continuously sends requests to other system components each time it accesses the mobile network. If these requests are not sent that excessively, it will only drain your mobile’s battery at a quicker rate. But if the requests are repetitive and endless, they can be a reason why your app keeps crashing.

 

Remedy: Make sure your app does not use much network when it is running in the background. By monitoring app usage critically, you can have an idea about your app’s internet usage. Experts suggest the app Battery Historian for this purpose.

 

Conclusion:

When an app suddenly stops working, it results in an app crash. An app crash can force users to give poor reviews or, ultimately, uninstall the app, causing heavy financial losses to the developers and programmers. An app crash can occur due to numerous reasons. There might be some testing issues, problems with memory management, or an unstable network connection. But, an app crash can be avoided if the right remedies are implemented. We hope that your app runs seamlessly and smoothly on the users’ mobile phones and has all the information you need regarding an app crash.
