Android App Development for Electronics Designers

Android is installed on more than two billion mobile devices around the world. Developers have created nearly four million apps.

Many major phone manufacturers, such as HTC, Huawei, and Lenovo, use Android. LG, Samsung, and Sony are also among them.

You may or may not have experience in Android development. Still, you already know how important preparation is to the success of any project.

The right resources and information will ensure that your project gets off to a good start. Why Develop for Android?

Android designers offers several benefits for developers:

• Cloud services and APIs: Android offers many APIs to help overcome limitations on mobile devices.

  These are typically smaller and have lower processing and memory power.

  You can overcome these limitations by developing your mobile app to use a cloud-based backend.

  You can reduce the load on the device's memory and computation by keeping the app as small as possible and making API calls that call services in the cloud.

  Google announces new APIs to access cloud-based services.

• Android Allows for Many Creative Options: When developing applications that use new technologies.

  Android was designed for touchscreen devices, such as mobile phones and tablets.

  Google also has Android variants for smartwatches, other wearables devices, in-car systems, and Internet of Things devices.

  You could create a dashboard app for a car that allows users to play music on Android devices, use Google Maps, and search Google.

  You can create an Android app for any car model.

• Google Play: Lets you easily distribute your Android application to customers, employees, or partners.

  Google Play has a few limitations for publishing apps, but the audience it reaches is enormous.

  Pay $25 for an account, and your app will appear on Google Play within 24 hours.

  Android is widely used, so your app can be run on many devices.

• Java is The Native language of Android: It's also one of the most popular programming languages.

  Java is a simple language to use when creating apps for Android.

  Native programming is possible, and you can easily use the native features of your mobile device.

  Java is designed to allow you to "write once and run anywhere." That means compiled Java code will run on any platform supporting Java without recompilation.

  The code can be run by any Java virtual computer, regardless of the architecture.

You'll also need some resources once you have decided on Android as the platform for your project. Many new developers start by visiting the Google homepage, leading them to Android's website.

You can also go straight to the Android Developer site.

You can find a wide range of useful resources on the site, such as:

• Get started with a sample code.
• Before you release your app, test it to ensure the behavior and usability are correct.
• App design and behavior guidelines that you can use to create your app.

Install Java on your computer and install the Java Development Kit (JDK). Install the Android SDK (Software Development Kit) required to develop Android applications.

You can reference or use the APIs to create your app. Google Chrome is the default browser when installing your operating system. However, you may choose to use another browser, such as Firefox.

Install Android Studio that comes with SDK. Studio is an official integrated development (IDE) environment for native Android.

Having an IDE that can help with coding and spell-checking, warnings about errors, UI design, etc., is important. Android Studio is based on JetBrains' IntelliJ software. It replaced Eclipse, which was previously used as an Android IDE.

C++ can be used for apps geared towards high performance, quick response, and reactivity. That is the reason why so many game developers use it.

Download the Android Native Development Kit (NDK) to reuse C++ in your Android application. The Android Native Development Kit (NDK) can implement C++ or C code in your apps.

The software also emulates Android for other operating systems, including Windows, Mac, and Linux. Android emulates Android by converting Android data into a format recognizable by other operating systems.

Android uses a design concept called material, which many enterprise applications use today. Android material design is a design guide that guides visual, interaction, and motion design.

That allows you to create an excellent user experience on all platforms and devices.

Apps that add value You want your mobile apps to be as competitive as you can. Incorporate services to improve user experience:

• Push Notifications: Can be a great way to keep users engaged by providing information on updates, special offers, events, and how to utilize key features.
• Mobile Analytics: AI-based mobile analytics can be used to add value to an app by answering questions from users, personalizing interactions with them, detecting fraud, or dealing with content in natural language.
• Functions-as-a-Service (FaaS): You can adopt a FaaS approach to development to gain cost efficiencies from running backend computing only when your app makes an API call to the cloud for a particular function.

  If you schedule push notifications every month, for example, you can use a FaaS only to pay for the time it takes to compute and send them.

1. Apps are Popular Because of Their Cool Features

The apps make our phones smarter, and their advantages have changed how we live today. Programmers adept at programming have been busy designing and developing their apps and adding features.

This article will explain the 5 Android Apps Development Fundamentals you need to know before beginning to program applications:

1. Learn the language
2. Familiarizing yourself with the appropriate application development environment and tools is important.
3. Application components: Knowledge and understanding.
4. Android application fragmentation, loading, tasks, threads, and loaders.
5. Selecting the Right Tools.
6. Learn the language

Java and XML is the main language used for Android App Development. To develop an Android application, you must have a solid understanding of these languages.

Java's fundamentals include the following:

• Packs
• Classes & objects
• Interfaces & Inheritance
• Strings & numbers, generics,
• The Collections
• Concurrency

Understanding Java and XML can help you create/develop a robust, elegant, and powerful Android application.

2. Understanding the Right Tools and Environment For Application Development

Before developing an Android App, it is important to familiarize yourself with the built-in development environment and tools for automating the development process.

The Android App Studio IDE and Eclipse are the best tools to use. They will teach you the basics as well as many other useful things. Learn Apache Maven and Apache Ant, as these tools provide powerful management features.

Please also familiarize yourself with the concepts and tools of source control. Create a git repository by learning git (creating a Bitbucket or GitHub account).

The Git Pocket Guide will help you understand how to use this platform and its basic terms.

3. Understanding The Application Components

The building blocks for Android apps are application components. The system enters your app through each component.

Each component is a separate entity that plays a particular role. However, some depend on one another and are not actual entry points.

Five different app components exist, each with its purpose and lifecycle that defines how it's created or destroyed.

These include:

Activities

It is an activity that displays a screen and has a user interface (for example, the email app could have a separate activity for composing new emails and another for reading them).

The activities work together to create a seamless user experience within the app. Each one is separate, but they all work together.

Services

It is an application component that runs in the background and performs work on remote processes. Remote Android designers can be useful to implement these processes remotely.

This component does not have a user interface (for example, it could play music while the user is in another app).

Content Providers

It is this component that manages the shared app data. This component allows you to query or modify data stored in an SQLite database, a file system on the internet, or, if the content provider permits, storing the data online or within.

The component can also be used to read and write data only shared within your application.

Receivers of Broadcasting

It is this component that responds to the system-wide announcements. The majority of broadcast receivers are part of the system.

Although they don't have a user interface, they can still display a notification in the status bar to alert the user if a broadcast occurs. It is usually a portal to other components and does only minimal work.

Activating Components

The intent is a synchronous message that activates three of the four components. Services, broadcast receivers, and activities are all part of the intent.

At runtime, intents can also be used to bind components together, whether they are part of your app.

4. Android Application Fragmentations: Threads, Loaders, Tasks, and Threads

Android has a fragmented marketplace with many devices and operating system versions. If your device is compatible with more versions and devices, it will require additional testing and maintenance.

It is equally true in the other direction. Using fonts, layouts, and appropriate assets for the screen is also necessary. Consider the range of Android-supported sensors and UI features.

Android apps all have an app class, one activity, or fragments.

You should run background services continuously at times, but not always. Always ensure the thread is not blocked if you want to provide a smooth and great user interface.

The long operations, such as computations, I/O, and network requests, should be run asynchronously in the background. All long operations (computations, I/O, network, etc.) should be performed asynchronously and in the background. It is, therefore, important that you learn about the Java Concurrency features.

5. Make the Right Choice When Choosing Tools

All you will need to develop Android apps are a Mac, Windows, Linux of any kind, Eclipse, ADT Plugin, and Android SDK.

These are all free. Google's installation guide will provide all the documentation to set up your development environment. Android has some special parameters you must consider when creating an Android application.

You can find them here:

• Performance and responsiveness.

  You must always be able to respond within 5 seconds of a user's input.

  Otherwise, your operating system may ANR.

  If your application is not responding, you can only force-close it.

• Users will notice lags greater than 100ms.

  As stated above, there should only be one UI thread.

• Use wake locks sparingly.

  Don't poll hardware unnecessarily (e.g., The battery will be quickly depleted if you use the GPS or accelerometer.
