Are you planning to perform the very first Android app development but have nothing in hand but an idea? Do you want to take a quick trip to get familiar with it?

If so, let’s go ahead and read our article about how to make an app especially, an Android app. We will also provide you with an Android app development guide to make this process happen easier!

What Techniques Are Involved in Android App Development Guide?

1. Wireframing

This is the very first step of any Android app development process, not only first but also important. Wireframes will outline the sizes and placement of page elements, site features, etc. And most of the time, the wireframe is made of lines, boxes, and grayscale colors.

People don’t just call it the blueprint or the skeleton of software, a website, an app, etc. for no reason. The wireframing stage is when you structure your app. Thanks to it, your design will be consistent from screen to screen. At the same time, it will make sure that your original ideas always go with the business strategy. 

Here are some tips you should consider using to make the wireframing phase happen easier and more effectively:

  • It’s important to sketch the flow first.
  • You must create a screen list (it might include the home page, product page, and review page, for example) beforehand.
  • Ensure your content scale well.
  • Ask for feedback from your colleagues frequently (to get rid of redundant elements, notice the missing important features, or come up with better ideas).

2. UI/UX Design

Many outsiders or beginners will feel unfamiliar or confused with these two terms.

In short, UI design is a set of tasks related to the interfaces of a product, or what users see on your web/app. The goals here are first, to produce effective control and operation of the product, and second, to create an easy, effective, and aesthetic web or app. All of these activities are performed to grab users’ attention.

As for UX design, designers must work their best to create a seamless experience for users. A good UX design should meet users’ needs when they are using your product. Thus, users might find pleasure to interact with your product. As a result, it will probably help you improve customer satisfaction and loyalty. 

Some tips you might want to use are:

  • Follow the Design for Android and Material Design Guideline by Google.
  • Add effect to let users know when a button is actionable. With Android, the trendy one at the moment is the Ripple effect.
  • You should also know a general principle: if it looks the same, it should act the same.
  • Keep in mind that there are thousands of Android devices out there, and you must help your product adapt to each of them.

3. Coding

The coding or development stage is divided into 2 layers which are the front-end and back-end.

The prior one concerns the client-side. Front-end developers or full-stack developers (who are responsible for both front and back-end development) will have to make the interfaces of your Android app as similar to the UI design as possible. As a result, users can see and interact with your app directly.

The most priority tasks of these developers are producing HTML, CSS, and JavaScript code as well as ensuring that the app is easy to use.

In the meantime, back-end development is all the things that cannot be seen by users. In other words, it helps the browser communicate with the database and vice versa. So, back-end developers are required to handle ‘behind-the-scenes’ functionalities of websites or apps.

They have to care for connecting websites or apps to a database, managing user connections, and powering the web or the app.

4. Testing

Not only developers but almost all people on this planet will likely miss their mistakes or errors in a process. That’s why we need testers (aka QCs) here to make sure your app has all the functionalities intended before as well as a seamless experience. So, basically, discovering glitches or errors is what these players do.

After catching those nasty bugs, testers will submit them to developers to fix them. As a result, your app will go as you have planned before or even better.

So, what tips testers could use to improve/enhance their testing process? People at Designveloper recommended you should:

  • Test the app in various conditions: different screen sizes (you could use cloud service to test on more devices), different internet speeds (or even when the internet connection is gone), etc.
  • Make sure the app follows platform guidelines.
  • Understand and test your app in unhappy scenarios.
  • Check functionalities first then move on to the user experience.

5. Deployment and market submission

So, we are almost finished with this round, the only thing left is to deploy your Android app on Google Play. This process is kind of easy, however, if you don’t pay close attention to it, this deployment stage will be a mess, especially when it comes to code signing. For more detail about this step, let’s read our article “iOS + Android Code Signing: What You Need To Know”.

And here are some things you should consider before/when deploying your Android app:

  • If your app size is too heavy, let’s break it into several parts. According to Clear Bridge, Android Expansion files allow the APK to add two more files, each of them up to 2GB in size. Google Play store will host and distribute these files at zero cost.
  • Think of some monetizing method beforehand, it will make your process happen faster when there is a price in your mind.
  • It’s important to remember that Google won’t allow you to change the price of your app if you set it a free one at the beginning.

6. Maintain and update

On the one hand, your testers, in most cases, will miss some bugs and errors on the app, and you have to maintain it frequently to avoid any uncomfortable experience.

On the other hand, just like any other industry, there are a whole lot of trends to follow from time to time. And trends are what could increase your users’ interest in your product. As a result, updating an app is also a critical activity to perform.

There are not many tips related to this stage, but we at Designveloper recommend you choose a good project management method to make the maintenance does not cost you much time and effort.

All in all, Agile is a good one to pick up and try. With this approach, you can also improve the quality of every stage of your Android app development process.

What is the best language to use for Android app development?

1. Java

Java is a programming language that is based on the concept of Objects.

It is said that this language is the first and most preferred one for Android app development. As a result, you can find it anywhere: Airbnb, Uber (based on Java), LinkedIn, etc. This happens since its code can be secured on a bunch of platforms, OSs, or architectures of devices.

Furthermore, since it’s widely used by developers all over the world, you can easily find support or solutions to your issues in various communities. Your development team is also able to work together remotely thanks to this distributed language.

2. Kotlin

Java is good, it, however, is kind of old and complex when compared to Kotlin.

According to Danlew, this 8-year-old language helps developers write more concise and effective code. Kotlin can present the errors in compile time. In addition, you can easily integrate it with Android Studio. It is also more streamlined and easier to read. The pros of Kotlin are various and we’ll introduce it to you in a future post.

Well, no wonder why people compare this one to Apple’s Swift.
