5 Android Mobile App Development Fundamentals

Master the Programming Language

Mastering Java and XLM is essential for Android mobile app development. According to New Relic, Java’s popularity continues, with a significant number of apps using Java 11 and Java 8 in production. The report also notes a 430% growth in the adoption of Java 17 within a year, indicating a strong and growing user base for Java. 

Java remains one of the top programming languages, with about 40.2% of developers using it in their projects. Its strengths include its multi-threaded capabilities, and architecture-neutral design, making it versatile for various apps from server and desktop environments to mobile devices. Despite the emergence of new programming languages, Java’s large development community, and more ensure its continued relevance and usage in significant projects by companies.

Navigating the Right Android Mobile App Development Tools and Platforms

Familiarity with the right mobile app development tools and environment is crucial for beginners in Android app development for several reasons. 

  • Ease the Learning Curve:

Using tools like Android Studio can significantly ease the learning process by providing a structured and feature-rich environment tailored for Android development. These tools offer build automation, integrated debugging, and testing facilities, which are essential for developing efficient and error-free apps​​.

  • Automate and Optimize the Build Process:

Moreover, understanding tools such as Apache Maven, Apache Ant, and Gradle is important as they offer a powerful set of tools for managing builds, which is a fundamental part of the development process. This knowledge helps in automating and optimizing the build process, managing dependencies, and ensuring that the app can be built consistently across different environments.

  • Manage Code Changes Efficiently:

Learning about source control tools and concepts, like Git, is also fundamental. Source control allows for efficient management of code changes, collaboration with other developers, and maintaining the history of project development, which is invaluable in any software development project​.

  • Create Intuitive and Responsive UI

Focusing on the design aspect, and understanding how to layout UI components using tools like the constraint layout in Android Studio is important for creating intuitive and responsive user interfaces. This knowledge aids in designing apps that can adapt to various device configurations, enhancing the UX across a wide range of Android devices​.

Have a Deep Knowledge of Mobile App Components

Have a Deep Knowledge of Mobile App Components

In Android mobile app development, app components serve as foundational elements, each acting as a potential entry point for the system into the app. These components, while functioning independently and serving unique roles, may also rely on each other. However, not every component serves as an entry point into the app.

Android app development comprises five key components, each with a unique function and lifecycle. They are activities, services, content providers, broadcast receivers, and activating components. Let’s take a look!

  • Activities

An activity in Android represents a distinct screen within the app’s UI, serving specific functions like displaying new emails, composing, or reading them. While these activities collectively enhance the app’s UX, making it seamless and integrated, each operates independently.

  • Services

This component operates behind the scenes to execute tasks for distant processes or extended activities without presenting a UI. For example, it could play music in the background even as the user interacts with a different app.

  • Content providers

This component oversees a collective pool of app data, enabling access and modifications to data stored in various locations. It also facilitates the handling of both shared and exclusive app data, streamlining the process of data management within the app.

  • Broadcast receivers

This component acts as a receiver for global messages from the Android system or apps, without showing any UI. It can, however, trigger notifications to inform the user about certain events. Essentially, it serves as a gateway to other mobile app components, performing only basic functions.

  • Activating components

An intent is a type of synchronous message that activates three key components in Android development: services, activities, and broadcast receivers. It serves as a link between components, allowing them to interact during runtime.

Mastering Android Tasks, Threads, and Data Management

The Android platform is like a diverse landscape with a wide array of devices and operating system versions. If you want your app to work well across many devices and versions, you’ll need to put in extra effort for maintenance and testing, which could also mean more costs. It’s important to pick the right fonts, assets, and layouts to ensure your app looks good on different screens.

Android supports a variety of sensors and UI elements, so consider those when developing your app. Every Android app is built around a core application class, with one or more activities where the main action happens, and sometimes fragments for modular parts of your activity.

For a smooth UX, avoid blocking the main thread with long tasks like calculations or network requests. These should be handled in the background, on a separate thread. This approach keeps your app responsive, making knowledge of Java’s concurrency tools quite valuable for managing these tasks efficiently.

Choosing the Right Needed Tools

Android Mobile App Development Tools

For initiating Android app development, the essential tools include a computer system, alongside Eclipse integrated development environment, and the Android Software Development Kit, all of which are available at no cost. Google offers a comprehensive installation guide that details the setup process for your development environment, encompassing all necessary documentation.

When developing for Android, it’s important to consider several key aspects to ensure optimal app performance and UX:

  • Responsiveness: An application should ideally process user inputs and respond within five seconds to prevent the system from displaying an Application Not Responding dialog. If the app fails to respond in this timeframe, the system may prompt the user to close the app forcefully.
  • UI Flexibility: It’s crucial to maintain a smooth UI, where any delay exceeding 100 milliseconds could be noticeable and potentially boring for users. The UI thread, being singular, should remain unobstructed to avoid any lag in the UI.
  • Resource Management: Efficient use of resources is vital. Specifically, wake locks should be employed judiciously. Additionally, frequent polling of hardware components like GPS or accelerometers should be minimized to conserve battery life.
