Irrespective of the error source, certain best practices can help you keep your app up at all times on most devices. Research reveals that the majority of Android app users can only tolerate an average daily crash rate of 0. Ratings and reviews often make all the difference when a prospective app user chooses between multiple competitors.
SEO algorithms also rely heavily on them. By beta testing your app, you can easily avoid the risk of piling up bad reviews that make your app unmarketable. A bad user experience can lead even the most loyal users to the competition. If you own an eCommerce app, you should be most worried about app crashes. A lot of effort goes into securing a conversion, so sing a buyer to technical errors is something you want to avoid.
Furthermore, apart from the inconvenience to the user, you suffer a lot in terms of development costs. In essence, being proactive about these issues will always prove beneficial to your entire mobile development process. To know where to look in case they happen to you in the future, here are 11 of the most prevalent causes of app crashes.
In enterprise-scale applications, in particular, proper memory management is a common challenge for developers. One of the major reasons why apps develop performance issues and trigger memory warnings is high memory usage. In extreme cases, these performance issues end up causing the app to terminate. When a mobile device OS requires more memory to perform tasks, the first course of action is to terminate high usage apps. In such circumstances, the user experience is sure to suffer tremendously.
At the top of the list are incorrect cache usage and retain cycles. Without proper sizing and configuration, cache usage can quickly grow and eat up existing memory. On the other hand, when two objects with a strong reference point at each other, a retain cycle is activated. The objects in the retain cycle can only get released when the app is terminated. One way to escape these issues is to only load memory objects large images, etc.
This not only helps to avoid crashes but also minimizes screen load times and boosts performance. You can also implement different actions, such as releasing non-compressed memory objects when you receive a memory warning. While doing so, bear in mind that the quality of testing is equally as important as how regularly you conduct it. This could mean trying it on different platforms, devices, resolutions, orientations, and even networks. For a clearer insight into the end-user experience, you need to test the entire app experience.
To fully manage your testing properly, we recommend powerful tools such as Shake. Considering how complicated mobile development can be, certain errors or exceptions are bound to occur. Regardless of how rigorous your testing cycles may have been, a memory issue, network condition, or sudden API change may sometimes go undetected. However, exceptions are also well known for causing invalid application states, leading to app crashes.
Exception handlers use a well-defined hierarchy to ensure that your app is prepared when a process falls into an exception path. As a mobile development best practice, handling exceptions as they occur may not be enough. Therefore, try using existing exception history and test environment responses to envisage and prevent future errors and exceptions. The best approach to writing code is to keep it minimal.
Stripping your app of excessive code may be one of your best efforts towards keeping it crash-free. Here are some certain areas you should focus on when looking to keep your code as light as possible:. They're archiving news from the last month. There's a level of corporate citizenship that needs to come up on mobile apps. Not that the problem is the same for all developers. But there is a trade-off. The iterative app development process, with its constant series of frequent releases, opens doors for getting to market with a minimum viable product and then improving it over time, building an audience.
But the loss of the traditional software lifecycle introduces significant complications because of dependencies on the operating system and third-party APIs. Or the OS gets updated and the app hasn't been updated. The growth of mobile and cloud computing has increased the use of third-party services, and their associated APIs, that save time and help get an app to market more quickly.
But they have their own set of issues. A developer changes mappings from a method name to an implementation, which allows modification of the original method when the original code, like an API from Apple, is unavailable.
APIs also can introduce unexpected modifications. Then there is the chain of dependencies for the APIs themselves, that creates a need for specialized tools to track everything. An API can also cause other problems, like memory errors. You're never sure what they're cleaning up and what they're creating.
The need for testing is obvious, but getting adequate coverage, particularly with the plethora of Android versions and devices, can be challenging. There are simulators, but software running on a server might not show the same performance limitations.
For example, one thread of an app might try to read a database at the same time a second thread is trying to modify the same database. It can be covered up with something as simple as a log statement.
There are services that run pairings of different devices and variations of operating systems and make them available, but that would likely be more expensive than a simulator.
The choice becomes a trade-off between budgets and needs. Testing should be combined with benchmarking against industry standards and user expectations to be sure that what seems acceptable to developers is also acceptable to users. Testing should also occur on a continuous basis. Monitor performance and look for user feedback suggesting problems, and then fix things as soon as possible.
If none of the common causes that we have pointed out above is happening in your machine then it would be good to seek help from a technician instead of trying to fix things by yourself which can cause even greater problems.

What Really Causes the Problem? Memory is Running Out Every computer has a limit in terms of storage space and whether you like it or not, this space will be consumed as you install and store more and more files to it. Programs Are Too Heavy on Processor or System Resource RAM Before installing any program or app, always make sure that your computer is able to meet the system requirements and other specifications.
Other Causes In other cases, there might be some advanced causes as to why your computer is freezing or hanging. Have A Tip? Have A Question? Goto Top. Windows Techies windowstechies.
