With contemporary people’ growing dependence on mobile apps in terms of business, their need for reliability also increase. However, mobile users keep seeing their apps crash, and in most cases such unexpected crashes happen when the least wanted.
Among the major causes of mobile app crashes there can be distinguished the following ones.
- Bad front-end optimization
You should effectively use the resources even if your app is local and it doesn’t address the back-end server. The problem can be solved by image compression or other strategies. However mobile apps developers should be still aware of the balance between the things happening on the screen and the things a device is capable of.
- Bandwidth constraints
Since mobile users nowadays expect very quick response times, too data payloads and inadequate bandwidth can also cause app crashes.
- Browser incompatibility
Problems with the browser are not merely a desktop phenomenon. Thus, Apple's performed a big job building the "walled garden" on Safari’s mobile version, but many interactions of apps, particularly on iOS, with Chrome as well as other different third-party browsers are still not tested.
- Database contention
Excessive sessions and bad queries and can drag performance down quickly. So, if you don’t have an indexed and properly optimized database, it is likely to perform poorly, thus, causing the app stop responding and providing bad UX.
- Demand of exceeding supply
This cause is a classic case demonstrating the risks hidden in your app’s success. Your app can crash because of being simultaneously discovered by millions of consumers at the same time.
- Device incompatibility
Since testing across all the Android devices is impossible, iOS has a significant amount of fragmentation, too.
- Fatal production bugs
Such bugs can appear in the time a new feature influencing another part of your app is introduced.
- Incorrect memory or CPU usage
This problem has arisen due to the appearance of a wide range of different devices apps can run on. Thus, you can’t assume that your app tested on a third generation 64-gig iPad will properly work on somebody’s first generation 8 gig iPhone etc.
- Integration dependencies
Your app’s usability can be tremendously affected by the way all back-end systems work together and deliver content to users.
- Network changes
At last, your app’s stability can also be affected by lost connections caused by switching between cellular networks and Wi-Fi. Developers account for this problem since it’s not normally solved by the operational system.
The above cases causing the majority of mobile crashes nowadays demonstrate the importance of timely and careful acceptance testing covering all the mentioned issues.
