  • Keep up to date with new technologies. You should always strive to improve your skills as a developer and be open to learning new things. No pun intended.

You probably already know the general responsibilities of an Android developer. Now let’s find out what it takes for you to be a great Android developer.

What skills to look for in Android app developers?

You must assess several technical skills to become the best Android app developer and deliver the best user experience.

Android basics

Understanding the basics of languages like C++, Java, and Kotlin is a crucial skill. It will help you create dynamic android apps.

So, android app developers should have programming experience with Java or Kotlin and an understanding of the core concepts. A good proficient understanding of concurrency, the collection framework, and multi-threading is a plus. It is also essential to understand the core concepts of Java, such as:

  • Java 8 is a popular version. Developers should be familiar with it.
  • The syntax is as vital as the most recent version because it describes how Java programs are created and interpreted. The developer must understand the syntax.
  • Java’s latest structures: Developers can create Android apps faster and with fewer errors if they understand the basics of program structure.

Important to note is that these functionalities are identical to Kotlin because they share many similarities with Java. Therefore, you must understand the core concepts to create seamless apps.


It is vital to prioritize interaction between Android apps and users. This improves user experience. But how to provide an enhanced experience?

While using drag and dropping, gestures, keyboard, and pan and zoom, you can do it. These are minor things that can make a huge difference in user experience. This user interaction is facilitated by Activity, an Android component that allows users to interact with one another.

As such, it is essential to evaluate your skills being an Android app developer. Make sure you can create interactive apps to improve usability and provide an outstanding user experience.

Android User Interface (UI)

A user interface is key to any application’s success. Most app users today want simple, intuitive, responsive, and engaging apps. The demand for intuitive UX/UI is higher. A report shows that more than half of all app users worldwide judge apps based on their first impressions.

Developers must have a solid understanding of Android app design and users’ preferences in today’s market. To develop Android apps that adhere to material design principles, every Android developer should follow some basic guidelines. These guidelines include using RecyclerView to create lists and grids, ConstraintLayout to design complex layouts, and animating for improved user experience while using vector drawables and appropriate menus.

UI navigation is a set of interactions that allows navigation between screens or parts of the content in a mobile app. Using tab bars and toolbars, you can implement user interface navigation.

The app bar or Toolbar is the fundamental base. It consists of pop-up menus and icons. In addition, you can open and close the navigation bar to implement effective navigation, which will help add menu items, exchange fragments and perform other related actions within the current activity.

Bottom Navigation View is yet another element that lets you move between various fragments through the tabs at the screen’s bottom.

You can switch between fragments (different pages) by selecting ViewPager from the Toolbar.

The key to building a power-packed Android app navigation system is user intention. Intents let users initiate new activities, share data, and switch to another platform within an app. Also, it is on certified Android developers whether they want implicit or explicit intent.

So, using the navigation in Android apps is an important skill.


Building and deploying a mobile application that increases its use is important. Your efforts will only be worthwhile if the app is reliable, scalable, and user-friendly. So, it is crucial to test the Android app before it is released in the market.

You can enjoy multiple options using your android app. For example, users may press the Submit button, download information, or even submit an application.

Before you assess your Android developer skills, ensure you can test different use cases and interactions. Expresso, Junit, and Robolectric are the most popular testing libraries for Android applications.

Cross-platform application development

It will be the cherry on the cake if you learn cross-platform app development because it lets you develop native-like applications for both Apple and Android using a single codebase.

Are you feeling surprised?

Well, that’s the power of cross-platform app development. Becoming an expert in it can unlock various opportunities for your career growth. 

This feature allows Android developers to create apps for multiple platforms at once, publish them to various app stores and reach their users on Android, iOS, or Windows quicker. In addition, Cross-platform app development means that there is only one code to be concerned with. This allows for easy bug fixing, fewer test runs, and easier deployment.

So make sure you can create apps that work across all three major mobile operating systems: Android, iOS, and Windows.

Database technologies

Mobile app databases contain structured information designed to meet the needs of mobile apps. Database management systems (DBMS) can manage, update and edit these databases.

To access and modify your app database, you will need to use Structured Query Language. Databases are essential for mobile app development because they can manage large amounts of data and provide privacy controls.

  • Dependable – App databases are highly reliable because the DBMS checking systems flag discrepancies and need to be corrected.
  • Secure – App databases offer security against theft and hacking. Multiple user logins can be created in a database management software (DBMS). Each new user must first be approved before they can access the database.
  • DBMS includes DML (Data Manipulation Languages), allowing easy updates of the app database.
  • Accessibility – Developers can search through an app’s databases within seconds using DBMS’s Data Query Languages (DQL).

Integration via API

The foundation of any mobile app strategy is an API. These APIs are essential to transform large amounts of data into usable frameworks on a mobile device. One of the critical skills in the Android app development course is API integration.

Nearly all mobile apps use APIs. This includes social media apps and banking apps. APIs offer a quick way to expand an enterprise’s reach beyond current limits. They are easy to integrate and allow for rapid delivery. Enterprises can expand their reach by bundling assets with those of partners and delivering them to the right mobile apps.

To ensure seamless integration and user experiences, you must hire an Android app developer familiar with APIs and third-party services.

Android security

Android comes with security features built in that prevent security problems. Certified Android developers must protect users’ privacy by asking permission. Content providers should also be cautious about the overall security model of their apps.

It is crucial for your app’s success that you have a strong understanding of security and how to implement it.

Git: Version control system

It seems impossible for various programmers to track the difficulties. This problem is made worse because mobile developers often work in teams. Fortunately, you can resolve this problem with version control systems, which provide app developers with an intuitive interface to make changes to their code. 

Git offers many features to help you develop Android apps. These include virtual team development via branching and merging, the ability to revert code changes that have caused performance degradation or defects, and code reviews via pull requests.

It is, therefore, an essential skill to have when hiring Android app developers. This allows mobile app developers to try new features and coding techniques and upgrade their applications without compromising existing versions.
