Android App development relies on good design and programming skills.

Successful Android app development hinges on strong design and programming skills. Developers must master the intricacies of programming languages and adhere to design principles and best practices. Clean, maintainable code is essential for creating intuitive, responsive, and user-friendly apps.


Kotlin, an open-source statically typed JVM programming language, has emerged as a preferred choice among developers for Android app development. Endorsed by Google and boasting features like conciseness, readability, and functional constructs, Kotlin offers seamless integration with Android Studio and full support for Android Jetpack Compose. Kotlin’s null safety features help prevent null pointer exceptions, a common error in Java. Its interoperability with Java and extensive ecosystem make it a versatile language for multiplatform development, including mobile applications with frameworks like KMM (Kotlin Multiplatform Mobile).


Java, a high-level language renowned for its platform independence and extensive API, played a pivotal role in Android app development until 2019. Bundled with Android Studio, the Java Development Kit (OpenJDK) facilitates programming in Java and interoperability with modern UI toolkits like Jetpack Compose. Developers leverage Java’s robust features, including its compiler, launcher, and documentation tools, to build powerful, portable Android apps.

Android Platform Architecture

The Android platform architecture comprises several layers that collaborate harmoniously to empower Android devices. Let’s explore these layers:

1. Linux Kernel:

At the core of the Android system lies the Linux Kernel, an open-source operating system component. Responsible for managing critical resources such as memory and processes, the Linux Kernel is the intermediary between the hardware and the upper layers of the Android stack. Its management of resources ensures efficient utilization and optimal performance of Android devices.

2. Hardware Abstraction Layer (HAL):

Sitting atop the Linux Kernel, the Hardware Abstraction Layer (HAL) introduces a crucial layer of abstraction. It bridges the gap between the device’s hardware components (e.g., camera, sensors, Bluetooth) and the higher layers of the Android system. The HAL empowers developers to write code seamlessly and interoperate across diverse hardware configurations by providing a standardized interface.

3. Android Runtime (ART):

Android Runtime (ART) is the default runtime for apps and system services that translates dex bytecode format files into native instructions. Its most relevant features are ahead-of-time compilation (AOT), garbage collection (GC), debugging options, and diagnostic and crash reports.

4. Android Java Framework:

An integral component of the Android ecosystem, the Android Java Framework furnishes developers with an extensive suite of Java-based APIs. These APIs empower developers to craft feature-rich Android applications, granting access to many functionalities. Key areas covered by these APIs include:

  • Resources: Facilitating seamless access and management of application resources such as images, strings, and layouts.
  • View System and Layouts: Enabling the creation of captivating user interfaces (UIs) through Views and Layouts.
  • Activities and Notifications: Empower developers to manage app screens (Activities) and notifications effortlessly.
  • Content Providers: Facilitating seamless data sharing between disparate applications.

Moreover, the Android Framework seamlessly integrates functionalities encapsulated within native C and C++ libraries, enriching the development experience.

5. System Apps:

The Android platform ships with a suite of essential system apps pre-installed on devices. These system apps deliver fundamental functionalities and serve as a resource that developer-created apps can leverage through the accessible APIs. They provide essential services such as telephony, messaging, and settings management, enhancing the overall user experience.

App Architecture

Modern app architectures prioritize user-driven interfaces and utilize modular components that can operate independently. This is crucial as the Android OS may kill app processes to free up resources based on user interactions or system conditions. Developers can create robust, maintainable, scalable applications by adhering to well-defined architectural principles.

Importance of App Architecture

A well-designed app architecture offers several key benefits:

  • Maintainability: A well-structured codebase with a clear separation of concerns allows developers to make changes and fix bugs more easily.
  • Scalability: The app’s modular architecture allows it to grow and adapt to increased user demand without major code rewrites.
  • Testability: Separating different functionalities allows each component to be tested in isolation, leading to more reliable and stable apps.

Principles and Best Practices

Here are some key principles and best practices to consider when designing an app architecture for Android development:

1. Separation of Concerns: This principle ensures that UI-based classes (Activities and Fragments) only contain logic for handling UI and operating system interactions. Data models, preferably persistent models, should drive the UI. This keeps UI components lean and avoids problems related to the component lifecycle.

2. Layered Architecture: A common Android app architecture utilizes two main layers:

  • UI Layer: This layer displays application data on the screen using UI elements (Views or Jetpack Compose) and state holders (like ViewModel classes).
  • Data Layer: This layer contains the business logic and exposes application data through repositories. Each repository can have zero to many data sources and is responsible for the following:
    • Exposing data
    • Centralizing data changes
    • Resolving conflicts between data sources
    • Abstracting data sources
    • Containing business logic

An optional domain layer between the UI and data layers can be added to encapsulate complex or reusable business logic.

3. Other Best Practices:

  • Single Source of Truth (SSOT): Assign a single component that can modify each data type (the SSOT).
  • Unidirectional Data Flow (UDF): State flows in one direction, with events modifying data flowing in the opposite direction.
  • Dependency Injection: Use patterns and libraries like Hilt to manage dependencies between components.
  • Focus on Core Functionality: Leverage Jetpack libraries and recommended libraries to avoid writing boilerplate code and focus on the unique core features of your app.
  • Testability: Ensure each part of the app is testable in isolation.

This holistic approach to design and development leads to a better user experience and a more efficient development process.

Specific architectural patterns, such as Model-View-ViewModel (MVVM) and Clean Architecture, can further enhance code organization and maintainability. Consider exploring these patterns in more detail to gain a deeper understanding.

App Components

Android apps are built using a combination of distinct components that each serve a specific purpose. These components are the essential building blocks of an Android app, and each is an entry point through which the system or a user can enter your app. There are four different types of app components: activities, services broadcast receivers, and content providers.

These components must be declared in the app manifest file, located at the root of the app’s project directory.  The app manifest provides essential information on the app components, activities, properties, and capabilities. It also describes permissions, package attributes (application ID), XLM elements, intent filter declarations (describing capabilities), API level, API libraries, icon and label attributes, hardware and software features needed by the app compatibility of devices, and minimum version. A manifest file is created, and elements are added during the app development.

In addition to declaring the app components, the manifest file also declares other important information about the app, such as its icon, version number, and any intent filters that describe the types of intents that the app’s components can handle.

App resources, such as images, audio files, and XML files, are also an important part of an Android app. These resources are defined in separate files within the app’s project directory and are assigned unique integer IDs. The Android SDK tools generate a special R class that contains references to these resources, making it easy to access them from your app’s code.

When designing the architecture of an Android app, it’s important to consider the specific problems the app intends to solve and the contexts in which it will be used. The approach to developing the app’s architecture may vary depending on these factors. Still, the core app components and the app manifest will always play a central role in the structure and behavior of the app.

One approach to migrating an app from Java to Kotlin is to adopt a phased strategy. Instead of attempting to convert the entire codebase at once, developers can start by introducing Kotlin gradually. They can begin by writing new code in Kotlin while leaving the existing Java code intact. Kotlin’s seamless interoperability with Java enables both languages to coexist within the same project, allowing for a smooth transition.

As the migration progresses, developers can prioritize converting the most critical or actively maintained parts of the codebase to Kotlin. This incremental approach reduces the risk of introducing bugs and allows the development team to become familiar with Kotlin’s syntax and best practices over time.

Kotlin’s concise and expressive syntax often results in more readable and maintainable code than Java. Migrating to Kotlin can reduce boilerplate code, improve null safety, and leverage advanced language features such as data classes, extension functions, and lambdas. These benefits can significantly enhance the overall quality and maintainability of the codebase.

However, it’s important to note that migrating an app from Java to Kotlin is challenging. Some Java libraries or frameworks may not have direct Kotlin equivalents, requiring additional effort to find suitable alternatives or adapt the existing code. Additionally, the migration process may necessitate updating dependencies, building configurations, and testing frameworks to ensure compatibility with Kotlin.

Despite these challenges, the benefits of migrating to Kotlin often outweigh the initial effort. Kotlin’s adoption can increase developer productivity, reduce code complexity, and improve app performance. It also positions the development team to take advantage of the latest Android features and libraries, which are increasingly built with Kotlin in mind.
