If your Android development crew has access to the kernel level APIs, they can create wonders like magically transforming the lock screen to something different or checking devices in real-time to ensure that there are no security threats.
The biggest challenge that you will face during Android app development is the testing that you need to do on countless devices or the various OS version combinations. It is obviously best if your app works perfectly on every Android device that is active and you can find on the market, but this requires a lot of testing.
Testing your app on almost every device type is something that is nearly impossible.
By combining real device testing and virtualized testing, you can make your application robust. After this process, the app can work well on a subset of almost 24,000 plus Android devices types.
Developing an app on Android takes a long time when you compare it to developing an iOS app. But if you spend the necessary time in testing and optimizing your app for widest possible functionality, you can create an app that deserves a five-star rating and one that works on all the Android devices.
