One of the problems that are being solved in 100s every month by developers. The core reason why an app could lose a potential user. Most wanted and the nightmare of developers, business.
Here are the top reasons why an android app crashes:
Unstable network conditions
Observed phone’s heating while traveling? Observed that app fails to retrieve data while switching between networks? Devices are extremely powerful nowadays and tend to switch between networks but it’s not the same case with Apps. While request of transition of any process from one network_state to another is quite often not handled by the apps. This also means transition between wifi to slower networks which most often leads to a timeout. A good app is tested for such situations to work reliably with or without networks and transitions.
Android versions and APIs
If we look at the Android distributed version and adoption, there are quite a number of APIs and libraries that need to be added to be able to support all 2 billion active users. Well, let’s consider there are 2 million downloads of your app in the playstore. Looking at a number of android versions, API level & supported libraries, even the slightest of non-sync might introduce crashes in a certain number of devices.
Careful monitoring of changes to the Android operating system and API updates should be included as part of the process.
Apps should not just run on a smartphone with 6GB RAM but also should work on devices with less than 512 MB. Memory isn’t freely available to provide the best experience. The processing power and availability are at extremes to be handled. There are also factors like the SDKs, background process, Activity life cycle management the network that is playing a vital role in memory management. Unlike iOS, Android lets you take control of memory and it’s well accessible internally to provide the best experience to the users.
App freezes, stop responding and eventually leading to crash. Multiple factors such as resources and images that are being downloaded and rendered are to be thought through. High-quality images on low-end smartphones would juice up battery and hog memory leading to frustration and uninstalls. Resources can be well optimized with open-source tools like Glide by Google for image loading and cache.
Due to this space of which there are several manufacturers, android versions and hardware specifications introducing huge challenge in sampling tests, devices, and conditions. Testing should be continuous and offer feedback to the app with efficiency and help developers for quick turn around for bug fixes with information. Think about what could possibly be a long term solution with a value that can put your app ahead of your competitions.
Is your process optimized? Is your code optimized? Can it face users with confidence? To know the answer of how your app performs and what can be optimized to make it better. Sign-up here at AppAchhi.com, we got you covered.
