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:. In contrast to the iOS development space, where everything is strictly controlled by Apple, Android working environments are far less predictable.

Fragmentation has always been a major challenge of the Android world and developers seem to always end up on the receiving end. As far back as , there were over 24, unique Android devices in use worldwide. Considering that Android devices account for Embedding the Android Support Library into your app can also help you support multiple API versions without any unnecessary code. For quite obvious reasons, cloud computing has experienced wide adoption in recent years.

The mobile development space has hopped onto this trend as well. However, these continuous interactions with cloud services have also exposed iOS and Android apps to another vulnerability—network problems.

These network management issues arise when your app is trying to access data over a network or from other third-party services. In such cases, if network access is unstable, the app can easily terminate while waiting for a response.

Changes in the network from 3G to 4G or losing reception in remote areas may also be responsible for these issues. It could also be related to the network bandwidth your app is built to handle.

If the issue is temporary and beyond your control, you may want to offer the user an offline version of the app. Alternatively, you could also redirect them to a particular line of action that may be of interest. For apps such as Instagram or Twitter that rely entirely on an internet connection, the only way out may be to display the most recently loaded version of the app.

At each step of the way, there are stage-specific issues that could compromise the stability of your app. Once the present flag is checked and ascertained as true, only then can your app proceed to the next event in the sequence. Why do my apps keep crashing on Android, How to fix it Advertisement. BI India Tech Bureau. One of the great things about Android is the vast number of apps and games available for download. There are millions of free apps spread across categories.

While many apps may just be alternatives of a popular app, there are enough quality apps that cater to the needs of most people. The Android world is diverse when it comes to both hardware and software. While this brings in options, it can also cause problems for app developers who have to code their apps to run on several different combinations of hardware as well as software.
