5 Common Mistakes That Most Android Developers Make

Becoming a successful android developer is beyond churning several mobile apps with excellent aesthetics and awesome features. Even though these aspects are quite important, the market(target users) demands have moved from those and are now focused on optimizing apps performances to improve users’ experience. And therefore, developers are now saddled with the responsibility of ensuring that there are no latency issues with their apps, as this could lead to poor user experience, which leads to revenue loss. Usually, this is the aftermath of users abandoning the app after encountering a few discomforts.

As an android developer, it is important to be aware of some of the mistakes that impact the overall performance of their app. If you are using Java programming language in your app development, you must know about the top 8 common Java errors to avoid as this could save you or your team a ton of money and resources while ensuring the end-users satisfactory experience is guaranteed.

5 Common Mistakes That Most Android Developers Make

1. Trying to Clone an IOS Application for Use on an Android Application

It is not surprising to use a similar application for Android and IOS devices in application development. However, cloning an android application from an IOS application is not ideal for the performance of an app. And if done, it could give birth to a variety of problems for the application. The most prominent of these problems revolve around sabotaging the experience of Users. For instance, if you choose to clone an IOS app with a static menu, users will experience some complexities in carrying out the same IOS functionalities on their android devices.

Cloning an IOS app doesn’t just hamper the User’s experience but also has a slew of usability issues. And this is a result of the inherent differences in design requirements for Android and IOS applications. The best way to avoid these issues is to build your Android applications from the general design standard rather than cloning an IOS app. When you clone an iOS application, many usability issues may completely disrupt how users interact with the program.

2. Failure to Utilize Background Thread

Usually, when an app is deployed, it initiates a new process in the background. This new process possesses a single main thread upon which all other apps execute. When you use this main thread to connect the app to the network, save and retrieve data, process images, and so on, you are blocking the main thread, which may cause the app to underperform. And it is not relevant that you blocked the main thread for some seconds; it can still create havoc with the application’s operation and make the overall experience unpleasant to users.

Therefore, if you intend to build an app with optimum user experience, it is advised that you execute background threads without interfering with the main thread for network connection, SD reading, and writing, database querying, image processing, bitmap loading, etc.

3. Working with one Device Specification in Mind

Usually, during app development, there is the temptation to use your cell phone as a standard. But doing this may preclude you from taking into cognizance the different models and specifications of mobile devices used by the potential users for which the app is to be created. Developing an app with one specific device in mind will give birth to many problems for users with different devices. For instance, the pixel count on your mobile phone may not be similar to that on another user’s phone. Also, the orientation of other users’ devices may differ from yours, thereby causing different inconsistencies in the application’s interface.

As a result, the app you create must run effortlessly across various devices without causing any interruptions in its performance. The app’s functionality should be responsive, and the UI/UX should be consistent across all apps. The app’s functionality should be responsive, and the UI/UX should be consistent across all apps. To achieve this, you should stick to the Android Development framework to guide you on writing codes that perform efficiently across any Android device, irrespective of the screen sizes and specifications.

4. Data Binding Isn’t Used Properly

The Inability to properly use data binding is one mistake most app developers are guilty of. Knowing how to use data binding properly helps to eliminate boilerplate code. It also helps to maximize your effort since you can now add more objects and functions with minimal lines of code. Also, the proper use of data binding provides you with the necessary tools to test the user interface. However, it would be best not to use data binding arbitrarily as it could lead to an expanded app’s size and build process. When using data binding, the goal is to ensure a balance in usage.

5. Not Utilizing Fragments

Both new and seasoned Android developers frequently overlook fragments. When building an app, it is considered an effective method to employ fragments whenever feasible. Fragments allow developers to make changes to UI components more quickly, reducing response time. You can view them as distinct building components inside an Activity, each having its own (complicated) life span. They aid in screen optimization, are readily handled by their parent activity, and may be reused, mixed, and positioned as needed. Creating a new activity for each app screen is wasteful since the system will retain them in memory for as long as possible. Thus, you can not free the others’ resources by killing one activity.


Now you know about the mistakes common to android developers, you must avoid these mistakes to ensure your app gets a fair chance at thriving in the mobile app industry. Also, don’t forget to add to your app’s development budget an amount for conducting proper testing on your app to fish out and fix any latency issues.

Are Android developers still in demand?

There is an extremely high demand for android developers, both entry-level and experienced. Android apps continue to grow in popularity, creating a wide range of opportunities.

What is a background Thread in Android?

Android apps use the main thread to handle UI updates and operations. Running long-running operations on the main thread can lead to app freezes, unresponsiveness, and thus a poor user experience.

Who invented Android?

The Android operating system was developed by Google (GOOGL) for use in all of its touchscreen devices, tablets, and cell phones. This operating system was first developed by Android, Inc., a software company located in Silicon Valley before it was acquired by Google in 2005.

What is a stack developer?

A full-stack developer is someone who works with the Back End – or server-side – of the application as well as the Front End, or client-side.

Why is Android programming so complicated?

Android development is complicated because Java is used for Android development and it is a verbose language. If there are more lines, it will be more complicated to understand, debug, or maintain code. Also, the IDE used in android development is usually Android Studio.
