This article mentions the top 10 Android app development mistakes that you must avoid in 2021.

1. Rewriting already existing code

This happens to be amongst the most common mistakes committed by Android app developers. Features like database access, network calls, image loading, JSON parsing, and social logins are features that are being used in virtually all the apps. It is a big mistake to rewrite code for all these features since it will be much time-consuming. 

These features already have regulations that have already been written and tested multiple times, and there is no need to rewrite them whatsoever. It is advisable to perform some research regarding existing codes to determine which ones have already been used in the app.

2. Incorrect usage of bitmaps

It is a fact that images are loved by the majority of smartphone users these days. Images will be able to convey plenty of info at a single glance. However, the most significant issue with displaying images will be that they consume a lot of memory. It is essential to load the image into memory before displaying it on the screen. The usage of bitmaps is amongst the most common strategies utilized by programmers for minimizing memory usage. 

Therefore, one needs to comprehend the concept of bitmaps for developing a useful mobile app. In case one does not have a comprehensive idea regarding bitmaps, he will not be able to create a useful Android app.

3. Not making use of minSdkVersion 14

This one is the most recent version which has been included in the Android application development kit. The developers must move on to the most current version with innovative features rather than working with older versions. Supporting older gadgets and smartphones makes the code more complicated in the long run, which becomes tough to maintain. 

This likewise stalls the process of development. In case you’d like to start afresh, it will be a sensible idea to rest to the older versions and embrace newer ones.

4. Not making use of ListView Hierarchy

It has been a long time since developers are using deep view hierarchy for layouts that come with an XML presentation in Android. It is essential to parse XML, measure the screen size, and list the elements accordingly for drawing the required content. 

This process can be resource-intensive as well as time-consuming, and it should be optimized. The list view helps to flatten the hierarchy, thus optimizing the whole process. As a result, the developers must use this process for accelerating their app development project.

5. Forcing the users to wait

The data packages will not be dispatched, approved, processed, as well as received instantly. On most occasions, the user needs to wait since there happens to be a time delay in the process. On some occasions, the network might fail, or packages might become destroyed, and the process might never be complete. However, it is possible to prevent this from happening. 

Unlike the unsuccessful network calls, the successful ones are more likely to take place. Consequently, it can be safely assumed that the process started will succeed on most occasions while the user is going to be notified in case of a rare failure. In the contemporary era, instantaneous feedback is expected by users from apps, and nobody likes to wait.
